* feat(balance): add replica placement validation for volume moves
When the volume balance detection proposes moving a volume, validate
that the move does not violate the volume's replication policy (e.g.,
ReplicaPlacement=010 requires replicas on different racks). If the
preferred destination violates the policy, fall back to score-based
planning; if that also violates, skip the volume entirely.
- Add ReplicaLocation type and VolumeReplicaMap to ClusterInfo
- Build replica map from all volumes before collection filtering
- Port placement validation logic from command_volume_fix_replication.go
- Thread replica map through collectVolumeMetrics call chain
- Add IsGoodMove check in createBalanceTask before destination use
* address PR review: extract validation closure, add defensive checks
- Extract validateMove closure to eliminate duplicated ReplicaLocation
construction and IsGoodMove calls
- Add defensive check for empty replica map entries (len(replicas) == 0)
- Add bounds check for int-to-byte cast on ExpectedReplicas (0-255)
* address nitpick: rp test helper accepts *testing.T and fails on error
Prevents silent failures from typos in replica placement codes.
* address review: add composite replica placement tests (011, 110)
Test multi-constraint placement policies where both rack and DC
rules must be satisfied simultaneously.
* address review: use struct keys instead of string concatenation
Replace string-concatenated map keys with typed rackKey/nodeKey
structs to eliminate allocations and avoid ambiguity if IDs
contain spaces.
* address review: simplify bounds check, log fallback error, guard source
- Remove unreachable ExpectedReplicas < 0 branch (outer condition
already guarantees > 0), fold bounds check into single condition
- Log error from planBalanceDestination in replica validation fallback
- Return false from IsGoodMove when sourceNodeID not found in
existing replicas (inconsistent cluster state)
* address review: use slices.Contains instead of hand-rolled helpers
Replace isAmongDC and isAmongRack with slices.Contains from the
standard library, reducing boilerplate.
* feat(plugin): add DC/rack/node filtering for volume balance detection
Add scoping filters so balance detection can be limited to specific data
centers, racks, or nodes. Filters are applied both at the metrics level
(in the handler) and at the topology seeding level (in detection) to
ensure only the targeted infrastructure participates in balancing.
* address PR review: use set lookups, deduplicate test helpers, add target checks
* address review: assert non-empty tasks in filter tests
Prevent vacuous test passes by requiring len(tasks) > 0
before checking source/target exclusions.
* address review: enforce filter scope in fallback, clarify DC filter
- Thread allowedServers into createBalanceTask so the fallback
planner cannot produce out-of-scope targets when DC/rack/node
filters are active
- Update data_center_filter description to clarify single-DC usage
* address review: centralize parseCSVSet, fix filter scope leak, iterate all targets
- Extract ParseCSVSet to shared weed/worker/tasks/util package,
remove duplicates from detection.go and volume_balance_handler.go
- Fix metric accumulation re-introducing filtered-out servers by
only counting metrics for servers that passed DC/rack/node filters
- Trim DataCenterFilter before matching to handle trailing spaces
- Iterate all task.TypedParams.Targets in filter tests, not just [0]
* remove useless descriptor string test
* feat(plugin): enhanced collection filtering for volume balance
Replace wildcard matching with three collection filter modes:
- ALL_COLLECTIONS (default): treat all volumes as one pool
- EACH_COLLECTION: run detection separately per collection
- Regex pattern: filter volumes by matching collection names
The EACH_COLLECTION mode extracts distinct collections from metrics
and calls Detection() per collection, sharing the maxResults budget
and clusterInfo (with ActiveTopology) across all calls.
* address PR review: fix wildcard→regexp replacement, optimize EACH_COLLECTION
* address nitpick: fail fast on config errors (invalid regex)
Add configError type so invalid collection_filter regex returns
immediately instead of retrying across all masters with the same
bad config. Transient errors still retry.
* address review: constants, unbounded maxResults, wildcard compat
- Define collectionFilterAll/collectionFilterEach constants to
eliminate magic strings across handler and metrics code
- Fix EACH_COLLECTION budget loop to treat maxResults <= 0 as
unbounded, matching Detection's existing semantics
- Treat "*" as ALL_COLLECTIONS for backward compat with wildcard
* address review: nil guard in EACH_COLLECTION grouping loop
* remove useless descriptor string test
* feat(balance): add volume state filter (ALL/ACTIVE/FULL)
Add a volume_state admin config field to the plugin worker volume balance
handler, matching the shell's -volumeBy flag. This allows filtering volumes
by state before balance detection:
- ALL (default): consider all volumes
- ACTIVE: only writable volumes below the size limit (FullnessRatio < 1.01)
- FULL: only read-only volumes above the size limit (FullnessRatio >= 1.01)
The 1.01 threshold mirrors the shell's thresholdVolumeSize constant.
* address PR review: use enum/select widget, switch-based filter, nil safety
- Change volume_state field from string/text to enum/select with
dropdown options (ALL, ACTIVE, FULL)
- Refactor filterMetricsByVolumeState to use switch with predicate
function for clearer extensibility
- Add nil-check guard to prevent panic on nil metric elements
- Add TestFilterMetricsByVolumeState_NilElement regression test
* feat(filer): add lazy directory listing for remote mounts
Directory listings on remote mounts previously only queried the local
filer store. With lazy mounts the listing was empty; with eager mounts
it went stale over time.
Add on-demand directory listing that fetches from remote and caches
results with a 5-minute TTL:
- Add `ListDirectory` to `RemoteStorageClient` interface (delimiter-based,
single-level listing, separate from recursive `Traverse`)
- Implement in S3, GCS, and Azure backends using each platform's
hierarchical listing API
- Add `maybeLazyListFromRemote` to filer: before each directory listing,
check if the directory is under a remote mount with an expired cache,
fetch from remote, persist entries to the local store, then let existing
listing logic run on the populated store
- Use singleflight to deduplicate concurrent requests for the same directory
- Skip local-only entries (no RemoteEntry) to avoid overwriting unsynced uploads
- Errors are logged and swallowed (availability over consistency)
* refactor: extract xattr key to constant xattrRemoteListingSyncedAt
* feat: make listing cache TTL configurable per mount via listing_cache_ttl_seconds
Add listing_cache_ttl_seconds field to RemoteStorageLocation protobuf.
When 0 (default), lazy directory listing is disabled for that mount.
When >0, enables on-demand directory listing with the specified TTL.
Expose as -listingCacheTTL flag on remote.mount command.
* refactor: address review feedback for lazy directory listing
- Add context.Context to ListDirectory interface and all implementations
- Capture startTime before remote call for accurate TTL tracking
- Simplify S3 ListDirectory using ListObjectsV2PagesWithContext
- Make maybeLazyListFromRemote return void (errors always swallowed)
- Remove redundant trailing-slash path manipulation in caller
- Update tests to match new signatures
* When an existing entry has Remote != nil, we should merge remote metadata into it rather than replacing it.
* fix(gcs): wrap ListDirectory iterator error with context
The raw iterator error was returned without bucket/path context,
making it harder to debug. Wrap it consistently with the S3 pattern.
* fix(s3): guard against nil pointer dereference in Traverse and ListDirectory
Some S3-compatible backends may return nil for LastModified, Size, or
ETag fields. Check for nil before dereferencing to prevent panics.
* fix(filer): remove blanket 2-minute timeout from lazy listing context
Individual SDK operations (S3, GCS, Azure) already have per-request
timeouts and retry policies. The blanket timeout could cut off large
directory listings mid-operation even though individual pages were
succeeding.
* fix(filer): preserve trace context in lazy listing with WithoutCancel
Use context.WithoutCancel(ctx) instead of context.Background() so
trace/span values from the incoming request are retained for
distributed tracing, while still decoupling cancellation.
* fix(filer): use Store.FindEntry for internal lookups, add Uid/Gid to files, fix updateDirectoryListingSyncedAt
- Use f.Store.FindEntry instead of f.FindEntry for staleness check and
child lookups to avoid unnecessary lazy-fetch overhead
- Set OS_UID/OS_GID on new file entries for consistency with directories
- In updateDirectoryListingSyncedAt, use Store.UpdateEntry for existing
directories instead of CreateEntry to avoid deleteChunksIfNotNew and
NotifyUpdateEvent side effects
* fix(filer): distinguish not-found from store errors in lazy listing
Previously, any error from Store.FindEntry was treated as "not found,"
which could cause entry recreation/overwrite on transient DB failures.
Now check for filer_pb.ErrNotFound explicitly and skip entries or
bail out on real store errors.
* refactor(filer): use errors.Is for ErrNotFound comparisons
* fix(helm): trim whitespace before s3 TLS args to prevent command breakage (#8613)
When global.enableSecurity is enabled, the `{{ include }}` call for
s3 TLS args lacked the leading dash (`{{-`), producing an extra blank
line in the rendered shell command. This broke shell continuation and
caused the filer (and s3/all-in-one) to crash because arguments after
the blank line were silently dropped.
* ci(helm): assert no blank lines in security+S3 command blocks
Renders the chart with global.enableSecurity=true and S3 enabled for
normal mode (filer + s3 deployments) and all-in-one mode, then parses
every /bin/sh -ec command block and fails if any contains blank lines.
This catches the whitespace regression from #8613 where a missing {{-
dash on the seaweedfs.s3.tlsArgs include produced a blank line that
broke shell continuation.
* ci(helm): enable S3 in all-in-one security render test
The s3.tlsArgs include is gated by allInOne.s3.enabled, so without
this flag the all-in-one command block wasn't actually exercising the
TLS args path.
* feat(remote): add -noSync flag to skip upfront metadata pull on mount
Made-with: Cursor
* refactor(remote): split mount setup from metadata sync
Extract ensureMountDirectory for create/validate; call pullMetadata
directly when sync is needed. Caller controls sync step for -noSync.
Made-with: Cursor
* fix(remote): validate mount root when -noSync so bad bucket/creds fail fast
When -noSync is used, perform a cheap remote check (ListBuckets and
verify bucket exists) instead of skipping all remote I/O. Invalid
buckets or credentials now fail at mount time.
Made-with: Cursor
* test(remote): add TestRemoteMountNoSync for -noSync mount and persisted mapping
Made-with: Cursor
* test(remote): assert no upfront metadata after -noSync mount
After remote.mount -noSync, run fs.ls on the mount dir and assert empty
listing so the test fails if pullMetadata was invoked eagerly.
Made-with: Cursor
* fix(remote): propagate non-ErrNotFound lookup errors in ensureMountDirectory
Return lookupErr immediately for any LookupDirectoryEntry failure that
is not filer_pb.ErrNotFound, so only the not-found case creates the
entry and other lookup failures are reported to the caller.
Made-with: Cursor
* fix(remote): use errors.Is for ErrNotFound in ensureMountDirectory
Replace fragile strings.Contains(lookupErr.Error(), ...) with
errors.Is(lookupErr, filer_pb.ErrNotFound) before calling CreateEntry.
Made-with: Cursor
* fix(remote): use LookupEntry so ErrNotFound is recognised after gRPC
Raw gRPC LookupDirectoryEntry returns a status error, not the sentinel,
so errors.Is(lookupErr, filer_pb.ErrNotFound) was always false. Use
filer_pb.LookupEntry which normalises not-found to ErrNotFound so the
mount directory is created when missing.
Made-with: Cursor
* test(remote): ignore weed shell banner in TestRemoteMountNoSync fs.ls count
Exclude master/filer and prompt lines from entry count so the assertion
checks only actual fs.ls output for empty -noSync mount.
Made-with: Cursor
* fix(remote.mount): use 0755 for mount dir, document bucket-less early return
Made-with: Cursor
* feat(remote.mount): replace -noSync with -metadataStrategy=lazy|eager
- Add -metadataStrategy flag (eager default, lazy skips upfront metadata pull)
- Accept lazy/eager case-insensitively; reject invalid values with clear error
- Rename TestRemoteMountNoSync to TestRemoteMountMetadataStrategyLazy
- Add TestRemoteMountMetadataStrategyEager and TestRemoteMountMetadataStrategyInvalid
Made-with: Cursor
* fix(remote.mount): validate strategy and remote before creating mount directory
Move strategy validation and validateMountRoot (lazy path) before
ensureMountDirectory so that invalid strategies or bad bucket/credentials
fail without leaving orphaned directory entries in the filer.
* refactor(remote.mount): remove unused remote param from ensureMountDirectory
The remote *RemoteStorageLocation parameter was left over from the old
syncMetadata signature. Only remoteConf.Name is used inside the function.
* doc(remote.mount): add TODO for HeadBucket-style validation
validateMountRoot currently lists all buckets to verify one exists.
Note the need for a targeted BucketExists method in the interface.
* refactor(remote.mount): use MetadataStrategy type and constants
Replace raw string comparisons with a MetadataStrategy type and
MetadataStrategyEager/MetadataStrategyLazy constants for clarity
and compile-time safety.
* refactor(remote.mount): rename MetadataStrategy to MetadataCacheStrategy
More precisely describes the purpose: controlling how metadata is
cached from the remote, not metadata handling in general.
* fix(remote.mount): remove validateMountRoot from lazy path
Lazy mount's purpose is to skip remote I/O. Validating via ListBuckets
contradicts that, especially on accounts with many buckets. Invalid
buckets or credentials will surface on first lazy access instead.
* fix(test): handle shell exit 0 in TestRemoteMountMetadataStrategyInvalid
The weed shell process exits with code 0 even when individual commands
fail — errors appear in stdout. Check output instead of requiring a
non-nil error.
* test(remote.mount): remove metadataStrategy shell integration tests
These tests only verify string output from a shell process that always
exits 0 — they cannot meaningfully validate eager vs lazy behavior
without a real remote backend.

* filer: propagate lazy metadata deletes to remote mounts
Delete operations now call the remote backend for mounted remote-only entries before removing filer metadata, keeping remote state aligned and preserving retry semantics on remote failures.
Made-with: Cursor
* filer: harden remote delete metadata recovery
Persist remote-delete metadata pendings so local entry removal can be retried after failures, and return explicit errors when remote client resolution fails to prevent silent local-only deletes.
Made-with: Cursor
* filer: streamline remote delete client lookup and logging
Avoid a redundant mount trie traversal by resolving the remote client directly from the matched mount location, and add parity logging for successful remote directory deletions.
Made-with: Cursor
* filer: harden pending remote metadata deletion flow
Retry pending-marker writes before local delete, fail closed when marking cannot be persisted, and start remote pending reconciliation only after the filer store is initialised to avoid nil store access.
Made-with: Cursor
* filer: avoid lazy fetch in pending metadata reconciliation
Use a local-only entry lookup during pending remote metadata reconciliation so cache misses do not trigger remote lazy fetches.
Made-with: Cursor
* filer: serialise concurrent index read-modify-write in pending metadata deletion
Add remoteMetadataDeletionIndexMu to Filer and acquire it for the full
read→mutate→commit sequence in markRemoteMetadataDeletionPending and
clearRemoteMetadataDeletionPending, preventing concurrent goroutines
from overwriting each other's index updates.
Made-with: Cursor
* filer: start remote deletion reconciliation loop in NewFiler
Move the background goroutine for pending remote metadata deletion
reconciliation from SetStore (where it was gated by sync.Once) to
NewFiler alongside the existing loopProcessingDeletion goroutine.
The sync.Once approach was problematic: it buried a goroutine launch
as a side effect of a setter, was unrecoverable if the goroutine
panicked, could race with store initialisation, and coupled its
lifecycle to unrelated shutdown machinery. The existing nil-store
guard in reconcilePendingRemoteMetadataDeletions handles the window
before SetStore is called.
* filer: skip remote delete for replicated deletes from other filers
When isFromOtherCluster is true the delete was already propagated to
the remote backend by the originating filer. Repeating the remote
delete on every replica doubles API calls, and a transient remote
failure on the replica would block local metadata cleanup — leaving
filers inconsistent.
* filer: skip pending marking for directory remote deletes
Directory remote deletes are idempotent and do not need the
pending/reconcile machinery that was designed for file deletes where
the local metadata delete might fail after the remote object is
already removed.
* filer: propagate remote deletes for children in recursive folder deletion
doBatchDeleteFolderMetaAndData iterated child files but only called
NotifyUpdateEvent and collected chunks — it never called
maybeDeleteFromRemote for individual children. This left orphaned
objects in the remote backend when a directory containing remote-only
files was recursively deleted.
Also fix isFromOtherCluster being hardcoded to false in the recursive
call to doBatchDeleteFolderMetaAndData for subdirectories.
* filer: simplify pending remote deletion tracking to single index key
Replace the double-bookkeeping scheme (individual KV entry per path +
newline-delimited index key) with a single index key that stores paths
directly. This removes the per-path KV writes/deletes, the base64
encoding round-trip, and the transaction overhead that was only needed
to keep the two representations in sync.
* filer: address review feedback on remote deletion flow
- Distinguish missing remote config from client initialization failure
in maybeDeleteFromRemote error messages.
- Use a detached context (30s timeout) for pending-mark and
pending-clear KV writes so they survive request cancellation after
the remote object has already been deleted.
- Emit NotifyUpdateEvent in reconcilePendingRemoteMetadataDeletions
after a successful retry deletion so downstream watchers and replicas
learn about the eventual metadata removal.
* filer: remove background reconciliation for pending remote deletions
The pending-mark/reconciliation machinery (KV index, mutex, background
loop, detached contexts) handled the narrow case where the remote
object was deleted but the subsequent local metadata delete failed.
The client already receives the error and can retry — on retry the
remote not-found is treated as success and the local delete proceeds
normally. The added complexity (and new edge cases around
NotifyUpdateEvent, multi-filer consistency during reconciliation, and
context lifetime) is not justified for a transient store failure the
caller already handles.
Remove: loopProcessingRemoteMetadataDeletionPending,
reconcilePendingRemoteMetadataDeletions, markRemoteMetadataDeletionPending,
clearRemoteMetadataDeletionPending, listPendingRemoteMetadataDeletionPaths,
encodePendingRemoteMetadataDeletionIndex, FindEntryLocal, and all
associated constants, fields, and test infrastructure.
* filer: fix test stubs and add early exit on child remote delete error
- Refactor stubFilerStore to release lock before invoking callbacks and
propagate callback errors, preventing potential deadlocks in tests
- Implement ListDirectoryPrefixedEntries with proper prefix filtering
instead of delegating to the unfiltered ListDirectoryEntries
- Add continue after setting err on child remote delete failure in
doBatchDeleteFolderMetaAndData to skip further processing of the
failed entry
* filer: propagate child remote delete error instead of silently continuing
Replace `continue` with early `break` when maybeDeleteFromRemote fails
for a child entry during recursive folder deletion. The previous
`continue` skipped the error check at the end of the loop body, so a
subsequent successful entry would overwrite err and the remote delete
error was silently lost. Now the loop breaks, the existing error check
returns the error, and NotifyUpdateEvent / chunk collection are
correctly skipped for the failed entry.
* filer: delete remote file when entry has Remote pointer, not only when remote-only
Replace IsInRemoteOnly() guard with entry.Remote == nil check in
maybeDeleteFromRemote. IsInRemoteOnly() requires zero local chunks and
RemoteSize > 0, which incorrectly skips remote deletion for cached
files (local chunks exist) and zero-byte remote objects (RemoteSize 0).
The correct condition is whether the entry has a remote backing object
at all.

* fix(helm): use componentName for all service names to fix truncation mismatch (#8610)
PR #8143 updated statefulsets and deployments to use the componentName
helper (which truncates the fullname before appending the suffix), but
left service definitions using the old `printf + trunc 63` pattern.
When release names are long enough, these two strategies produce
different names, causing DNS resolution failures (e.g., S3 cannot
find the filer-client service and falls back to localhost:8888).
Unify all service name definitions and cluster address helpers to use
the componentName helper consistently.
* refactor(helm): simplify cluster address helpers with ternary
* test(helm): add regression test for service name truncation with long release names
Renders the chart with a >63-char fullname in both normal and all-in-one
modes, then asserts that Service metadata.name values match the hostnames
produced by cluster.masterAddress, cluster.filerAddress, and the S3
deployment's -filer= argument. Prevents future truncation/DNS mismatch
regressions like #8610.
* fix(helm-ci): limit S3_FILER_HOST extraction to first match
* fix(filer): limit concurrent proxy reads per volume server
Add a per-volume-server semaphore (default 16) to proxyToVolumeServer
to prevent replication bursts from overwhelming individual volume
servers with hundreds of concurrent connections, which causes them
to drop connections with "unexpected EOF".
Excess requests queue up and respect the client's context, returning
503 if the client disconnects while waiting.
Also log io.CopyBuffer errors that were previously silently discarded.

is ever called without a matching acquire.

* fix(replication): resume partial chunk reads on EOF instead of re-downloading
When replicating chunks and the source connection drops mid-transfer,
accumulate the bytes already received and retry with a Range header
to fetch only the remaining bytes. This avoids re-downloading
potentially large chunks from scratch on each retry, reducing load
on busy source servers and speeding up recovery.
* test(replication): add tests for downloadWithRange including gzip partial reads
Tests cover:
- No offset (no Range header sent)
- With offset (Range header verified)
- Content-Disposition filename extraction
- Partial read + resume: server drops connection mid-transfer, client
resumes with Range from the offset of received bytes
- Gzip partial read + resume: first response is gzip-encoded (Go auto-
decompresses), connection drops, resume request gets decompressed data
(Go doesn't add Accept-Encoding when Range is set, so the server
decompresses), combined bytes match original
* fix(replication): address PR review comments
- Consolidate downloadWithRange into DownloadFile with optional offset
parameter (variadic), eliminating code duplication (DRY)
- Validate HTTP response status: require 206 + correct Content-Range
when offset > 0, reject when server ignores Range header
- Use if/else for fullData assignment for clarity
- Add test for rejected Range (server returns 200 instead of 206)
* refactor(replication): remove unused ReplicationSource interface
The interface was never referenced and its signature didn't match
the actual FilerSource.ReadPart method.

* feat(security): add [admin] section to security.toml scaffold
Add admin credential fields (user, password, readonly.user,
readonly.password) to security.toml. Via viper's WEED_ env prefix and
AutomaticEnv(), these are automatically overridable as WEED_ADMIN_USER,
WEED_ADMIN_PASSWORD, etc.
Ref: https://github.com/seaweedfs/seaweedfs/discussions/8586
* feat(admin): support env var and security.toml fallbacks for credentials
Add applyViperFallback() to read admin credentials from security.toml /
WEED_* environment variables when CLI flags are not explicitly set.
This allows systems like NixOS to pass secrets via env vars instead of
CLI flags, which appear in process listings.
Precedence: CLI flag > env var / security.toml > default value.
Also change -adminUser default from "admin" to "" so that credentials
are fully opt-in.
Ref: https://github.com/seaweedfs/seaweedfs/discussions/8586
* feat(helm): use WEED_ env vars for admin credentials instead of CLI flags
Rename SEAWEEDFS_ADMIN_USER/PASSWORD to WEED_ADMIN_USER/PASSWORD so
viper picks them up natively. Remove -adminUser/-adminPassword shell
expansion from command args since the Go binary now reads these
directly via viper.
* docs(admin): document env var and security.toml credential support
Add environment variable mapping table, security.toml example, and
precedence rules to the admin README.
* style(security): use nested [admin.readonly] table in security.toml
Use a nested TOML table instead of dotted keys for the readonly
credentials. More idiomatic and easier to read; no change in how
Viper parses it.
* fix(admin): use util.GetViper() for env var support and fix README example
applyViperFallback() was using viper.GetString() directly, which
bypasses the WEED_ env prefix and AutomaticEnv setup that only
happens in util.GetViper(). Switch to util.GetViper().GetString()
so WEED_ADMIN_* environment variables are actually picked up.
Also fix the README example to include WEED_ADMIN_USER alongside
WEED_ADMIN_PASSWORD, since runAdmin() rejects an empty username
when a password is set.
* fix(admin): restore default adminUser to "admin"
Defaulting adminUser to "" broke the common flow of setting only
WEED_ADMIN_PASSWORD — runAdmin() rejects an empty username when a
password is set. Restore "admin" as the default so that setting
only the password works out of the box.
* docs(admin): align README security.toml example with scaffold format
Use nested [admin.readonly] table instead of flat dotted keys to
match the format in weed/command/scaffold/security.toml.
* docs(admin): remove README.md in favor of wiki page
Admin documentation lives at the wiki (Admin-UI.md). Remove the
in-repo README to avoid maintaining duplicate docs.

The log message was comparing against the planned size of the destination
volume (including volumes already planned to merge into it) but only
displaying the raw volume size, making the output confusing when the
displayed sizes clearly didn't add up to exceed the limit.
When getEncryptionConfiguration encounters a not-found error (e.g.,
during bucket recreation after a partial delete), return
ErrNoSuchBucketEncryptionConfiguration instead of ErrInternalError.
This prevents uploads from failing with 500 errors during recovery.
When autoCreateBucket finds the bucket already exists, remove it from
the negative cache so subsequent requests don't unnecessarily trigger
another auto-create attempt.
Clarify the comment and log message for the case where a collection
exists but the bucket directory is missing, explaining the root cause
(partial deletion) more precisely.
Reorder DeleteBucketHandler to remove the bucket directory first, then
delete the collection. If collection deletion fails, the bucket is still
effectively deleted and can be recreated. Previously, if directory
deletion succeeded but collection deletion failed, the bucket was left
in an unrecoverable state.
* fix(s3api): allow bucket recreation when orphaned collection exists (#8601)
When a bucket is deleted, its filer directory is removed but the
underlying collection/volumes may not be fully cleaned up yet. If the
bucket is immediately recreated, PutBucketHandler was returning
ErrBucketAlreadyExists due to the orphaned collection, blocking bucket
recreation and causing subsequent uploads to fail with InternalError.
Allow bucket creation to proceed when a collection exists without a
corresponding bucket directory, since this is a transient orphaned state
from a previous deletion.
* fix(s3api): handle concurrent bucket creation race in mkdir
On mkdir failure, re-check whether the bucket directory now exists
and return BucketAlreadyExists instead of InternalError when another
request created the bucket concurrently.
remote.uncache checks LastLocalSyncTsNs to determine if a file has been
synced to remote. remote.copy.local was not setting this field, leaving
it at 0, which caused uncache to skip all files uploaded via
remote.copy.local.
Fixes#8602
* Reduce task logger noise: stop duplicating every log entry to glog and stderr
Every task log entry was being tripled: written to the task log file,
forwarded to glog (which writes to /tmp by default with no rotation),
and echoed to stderr. This caused glog files to fill /tmp on long-running
workers.
- Remove INFO/DEBUG forwarding to glog (only ERROR/WARNING remain)
- Remove stderr echo of every log line
- Remove fsync on every single log write (unnecessary for log files)
* Fix glog call depth for correct source file attribution
The call stack is: caller → Error() → log() → writeLogEntry() →
glog.ErrorDepth(), so depth=4 is needed for glog to report the
original caller's file and line number.
fix(s3api): ListObjects with trailing-slash prefix returns wrong results
When ListObjectsV2 is called with a prefix ending in "/" (e.g., "foo/"),
normalizePrefixMarker strips the trailing slash and splits into
dir="parent" and prefix="foo". The filer then lists entries matching
prefix "foo", which returns both directory "foo" and "foo1000".
The prefixEndsOnDelimiter guard correctly identifies directory "foo" as
the target and recurses into it, but then resets the guard to false.
The loop continues and incorrectly recurses into "foo1000" as well,
causing the listing to return objects from unrelated directories.
Fix: after recursing into the exact directory targeted by the
trailing-slash prefix, return immediately from the listing loop.
There is no reason to process sibling entries since the original
prefix specifically targeted one directory.
* Add tests for AWS user principal in AssumeRole trust policies
Add test cases that verify trust policy validation when using specific
AWS user principals (e.g., "arn:aws:iam::000000000000:user/backend")
in the Principal field of trust policies for AssumeRole.
Covers single user, multiple users (array), wildcard, and plain string
principal formats. These tests demonstrate the bug reported in #8588
where specific user principals always fail validation.
* Populate RequestContext in ValidateTrustPolicyForPrincipal
ValidateTrustPolicyForPrincipal was creating an EvaluationContext with
a nil RequestContext. The policy engine's principal matching logic looks
up "aws:PrincipalArn" in RequestContext for non-wildcard principals,
so specific user ARNs like "arn:aws:iam::000000000000:user/backend"
always failed to match, while wildcard "*" worked because it
short-circuits before the lookup.
Populate RequestContext with both "principal" and "aws:PrincipalArn"
keys, consistent with how IsActionAllowed already does it.
Fixes#8588
* Remove GitHub discussion URL from source code comments
* Add specific error message assertions in trust policy tests
Fix plugin configuration tab layout overflow (#8587)
Remove h-100 from Job Scheduling Settings card, which caused it to
stretch to 100% of the row height and push the Next Run card below
the row boundary, overflowing into the Detection Results section.
* Stop deleting counter metrics during bucket TTL cleanup
Counter metrics (traffic bytes, request counts, object counts) are
monotonically increasing by design. Deleting them after 10 minutes of
bucket inactivity causes them to vanish from /metrics output and reset
to zero when traffic resumes, breaking Prometheus rate()/increase()
queries and making historical traffic reporting impossible.
Only delete gauges and histograms in the TTL cleanup loop, as these
represent current state and are safely re-populated on next activity.
Fixes https://github.com/seaweedfs/seaweedfs/issues/8521
* Clean up all bucket metrics on bucket deletion
Add DeleteBucketMetrics() to delete all metrics (including counters)
for a bucket when it is explicitly deleted. This prevents unbounded
label cardinality from accumulating for buckets that no longer exist.
Called from DeleteBucketHandler after successful bucket deletion.
* Reduce mutex scope in bucket metrics TTL sweep
Collect expired bucket names under the lock, then release before
calling DeletePartialMatch on Prometheus metrics. This prevents
RecordBucketActiveTime from blocking during the expensive cleanup.

* Remove misleading Workers sub-menu items from admin sidebar
The sidebar sub-items (Job Detection, Job Queue, Job Execution,
Configuration) always navigated to the first job type's tabs
(typically EC Encoding) rather than showing cross-job-type views.
This was confusing as noted in #8590. Since the in-page tabs already
provide this navigation, remove the redundant sidebar sub-items and
keep only the top-level Workers link.
Fixes#8590
* Update layout_templ.go
* add dynamic timeouts to plugin worker vacuum gRPC calls
All vacuum gRPC calls used context.Background() with no deadline,
so the plugin scheduler's execution timeout could kill a job while
a large volume compact was still in progress. Use volume-size-scaled
timeouts matching the topology vacuum approach: 3 min/GB for compact,
1 min/GB for check, commit, and cleanup.
Fixes#8591
* scale scheduler execution timeout by volume size
The scheduler's per-job execution timeout (default 240s) would kill
vacuum jobs on large volumes before they finish. Three changes:
1. Vacuum detection now includes estimated_runtime_seconds in job
proposals, computed as 5 min/GB of volume size.
2. The scheduler checks for estimated_runtime_seconds in job
parameters and uses it as the execution timeout when larger than
the default — a generic mechanism any handler can use.
3. Vacuum task gRPC calls now use the passed-in ctx as parent
instead of context.Background(), so scheduler cancellation
propagates to in-flight RPCs.
* extend job type runtime when proposals need more time
The JobTypeMaxRuntime (default 30 min) wraps both detection and
execution. Its context is the parent of all per-job execution
contexts, so even with per-job estimated_runtime_seconds, jobCtx
would cancel everything when it expires.
After detection, scan proposals for the maximum
estimated_runtime_seconds. If any proposal needs more time than
the remaining JobTypeMaxRuntime, create a new execution context
with enough headroom. This lets large vacuum jobs complete without
being killed by the job type deadline while still respecting the
configured limit for normal-sized jobs.
* log missing volume size metric, remove dead minimum runtime guard
Add a debug log in vacuumTimeout when t.volumeSize is 0 so
operators can investigate why metrics are missing for a volume.
Remove the unreachable estimatedRuntimeSeconds < 180 check in
buildVacuumProposal — volumeSizeGB always >= 1 (due to +1 floor),
so estimatedRuntimeSeconds is always >= 300.
* cap estimated runtime and fix status check context
- Cap maxEstimatedRuntime and per-job timeout overrides to 8 hours
to prevent unbounded timeouts from bad metrics.
- Check execCtx.Err() instead of jobCtx.Err() for status reporting,
since dispatch runs under execCtx which may have a longer deadline.
A successful dispatch under execCtx was misreported as "timeout"
when jobCtx had expired.
* check for nil needle map before compaction sync
When CommitCompact runs concurrently, it sets v.nm = nil under
dataFileAccessLock. CompactByIndex does not hold that lock, so
v.nm.Sync() can hit a nil pointer. Add an early nil check to
return an error instead of crashing.
Fixes#8591
* guard copyDataBasedOnIndexFile size check against nil needle map
The post-compaction size validation at line 538 accesses
v.nm.ContentSize() and v.nm.DeletedSize(). If CommitCompact has
concurrently set v.nm to nil, this causes a SIGSEGV. Skip the
validation when v.nm is nil since the actual data copy uses local
needle maps (oldNm/newNm) and is unaffected.
Fixes#8591
* use atomic.Bool for compaction flags to prevent concurrent vacuum races
The isCompacting and isCommitCompacting flags were plain bools
read and written from multiple goroutines without synchronization.
This allowed concurrent vacuums on the same volume to pass the
guard checks and run simultaneously, leading to the nil pointer
crash. Using atomic.Bool with CompareAndSwap ensures only one
compaction or commit can run per volume at a time.
Fixes#8591
* use go-version-file in CI workflows instead of hardcoded versions
Use go-version-file: 'go.mod' so CI automatically picks up the Go
version from go.mod, avoiding future version drift. Reordered
checkout before setup-go in go.yml and e2e.yml so go.mod is
available. Removed the now-unused GO_VERSION env vars.
* capture v.nm locally in CompactByIndex to close TOCTOU race
A bare nil check on v.nm followed by v.nm.Sync() has a race window
where CommitCompact can set v.nm = nil between the two. Snapshot
the pointer into a local variable so the nil check and Sync operate
on the same reference.
* add dynamic timeouts to plugin worker vacuum gRPC calls
All vacuum gRPC calls used context.Background() with no deadline,
so the plugin scheduler's execution timeout could kill a job while
a large volume compact was still in progress. Use volume-size-scaled
timeouts matching the topology vacuum approach: 3 min/GB for compact,
1 min/GB for check, commit, and cleanup.
Fixes#8591
* Revert "add dynamic timeouts to plugin worker vacuum gRPC calls"
This reverts commit 80951934c3.
* unify compaction lifecycle into single atomic flag
Replace separate isCompacting and isCommitCompacting flags with a
single isCompactionInProgress atomic.Bool. This ensures CompactBy*,
CommitCompact, Close, and Destroy are mutually exclusive — only one
can run at a time per volume.
Key changes:
- All entry points use CompareAndSwap(false, true) to claim exclusive
access. CompactByVolumeData and CompactByIndex now also guard v.nm
and v.DataBackend with local captures.
- Close() waits for the flag outside dataFileAccessLock to avoid
deadlocking with CommitCompact (which holds the flag while waiting
for the lock). It claims the flag before acquiring the lock so no
new compaction can start.
- Destroy() uses CAS instead of a racy Load check, preventing
concurrent compaction from racing with volume teardown.
- unmountVolumeByCollection no longer deletes from the map;
DeleteCollectionFromDiskLocation removes entries only after
successful Destroy, preventing orphaned volumes on failure.
Fixes#8591
The SchedulerConfig struct and its persistence/API were unnecessary
indirection. Replace with a simple constant (reduced from 613s to 61s)
so the scheduler re-checks for detectable job types promptly after
going idle, improving the clean-install experience.
* proto: add BalanceMoveSpec and batch fields to BalanceTaskParams
Add BalanceMoveSpec message for encoding individual volume moves,
and max_concurrent_moves + repeated moves fields to BalanceTaskParams
to support batching multiple volume moves in a single job.
* balance handler: add batch execution with concurrent volume moves
Refactor Execute() into executeSingleMove() (backward compatible) and
executeBatchMoves() which runs multiple volume moves concurrently using
a semaphore-bounded goroutine pool. When BalanceTaskParams.Moves is
populated, the batch path is taken; otherwise the single-move path.
Includes aggregate progress reporting across concurrent moves,
per-move error collection, and partial failure support.
* balance handler: add batch config fields to Descriptor and worker config
Add max_concurrent_moves and batch_size fields to the worker config
form and deriveBalanceWorkerConfig(). These control how many volume
moves run concurrently within a batch job and the maximum batch size.
* balance handler: group detection proposals into batch jobs
When batch_size > 1, the Detect method groups detection results into
batch proposals where each proposal encodes multiple BalanceMoveSpec
entries in BalanceTaskParams.Moves. Single-result batches fall back
to the existing single-move proposal format for backward compatibility.
* admin UI: add volume balance execution plan and batch badge
Add renderBalanceExecutionPlan() for rich rendering of volume balance
jobs in the job detail modal. Single-move jobs show source/target/volume
info; batch jobs show a moves table with all volume moves.
Add batch badge (e.g., "5 moves") next to job type in the execution
jobs table when the job has batch=true label.
* Update plugin_templ.go
* fix: detection algorithm uses greedy target instead of divergent topology scores
The detection loop tracked effective volume counts via an adjustments map,
but createBalanceTask independently called planBalanceDestination which used
the topology's LoadCount — a separate, unadjusted source of truth. This
divergence caused multiple moves to pile onto the same server.
Changes:
- Add resolveBalanceDestination to resolve the detection loop's greedy
target (minServer) rather than independently picking a destination
- Add oscillation guard: stop when max-min <= 1 since no single move
can improve the balance beyond that point
- Track unseeded destinations: if a target server wasn't in the initial
serverVolumeCounts, add it so subsequent iterations include it
- Add TestDetection_UnseededDestinationDoesNotOverload
* fix: handler force_move propagation, partial failure, deterministic dedupe
- Propagate ForceMove from outer BalanceTaskParams to individual move
TaskParams so batch moves respect the force_move flag
- Fix partial failure: mark job successful if at least one move
succeeded (succeeded > 0 || failed == 0) to avoid re-running
already-completed moves on retry
- Use SHA-256 hash for deterministic dedupe key fallback instead of
time.Now().UnixNano() which is non-deterministic
- Remove unused successDetails variable
- Extract maxProposalStringLength constant to replace magic number 200
* admin UI: use template literals in balance execution plan rendering
* fix: integration test handles batch proposals from batched detection
With batch_size=20, all moves are grouped into a single proposal
containing BalanceParams.Moves instead of top-level Sources/Targets.
Update assertions to handle both batch and single-move proposal formats.
* fix: verify volume size on target before deleting source during balance
Add a pre-delete safety check that reads the volume file status on both
source and target, then compares .dat file size and file count. If they
don't match, the move is aborted — leaving the source intact rather than
risking irreversible data loss.
Also removes the redundant mountVolume call since VolumeCopy already
mounts the volume on the target server.
* fix: clamp maxConcurrent, serialize progress sends, validate config as int64
- Clamp maxConcurrentMoves to defaultMaxConcurrentMoves before creating
the semaphore so a stale or malicious job cannot request unbounded
concurrent volume moves
- Extend progressMu to cover sender.SendProgress calls since the
underlying gRPC stream is not safe for concurrent writes
- Perform bounds checks on max_concurrent_moves and batch_size in int64
space before casting to int, avoiding potential overflow on 32-bit
* fix: check disk capacity in resolveBalanceDestination
Skip disks where VolumeCount >= MaxVolumeCount so the detection loop
does not propose moves to a full disk that would fail at execution time.
* test: rename unseeded destination test to match actual behavior
The test exercises a server with 0 volumes that IS seeded from topology
(matching disk type), not an unseeded destination. Rename to
TestDetection_ZeroVolumeServerIncludedInBalance and fix comments.
* test: tighten integration test to assert exactly one batch proposal
With default batch_size=20, all moves should be grouped into a single
batch proposal. Assert len(proposals)==1 and require BalanceParams with
Moves, removing the legacy single-move else branch.
* fix: propagate ctx to RPCs and restore source writability on abort
- All helper methods (markVolumeReadonly, copyVolume, tailVolume,
readVolumeFileStatus, deleteVolume) now accept a context parameter
instead of using context.Background(), so Execute's ctx propagates
cancellation and timeouts into every volume server RPC
- Add deferred cleanup that restores the source volume to writable if
any step after markVolumeReadonly fails, preventing the source from
being left permanently readonly on abort
- Add markVolumeWritable helper using VolumeMarkWritableRequest
* fix: deep-copy protobuf messages in test recording sender
Use proto.Clone in recordingExecutionSender to store immutable snapshots
of JobProgressUpdate and JobCompleted, preventing assertions from
observing mutations if the handler reuses message pointers.
* fix: add VolumeMarkWritable and ReadVolumeFileStatus to fake volume server
The balance task now calls ReadVolumeFileStatus for pre-delete
verification and VolumeMarkWritable to restore writability on abort.
Add both RPCs to the test fake, and drop the mountCalls assertion since
BalanceTask no longer calls VolumeMount directly (VolumeCopy handles it).
* fix: use maxConcurrentMovesLimit (50) for clamp, not defaultMaxConcurrentMoves
defaultMaxConcurrentMoves (5) is the fallback when the field is unset,
not an upper bound. Clamping to it silently overrides valid config
values like 10/20/50. Introduce maxConcurrentMovesLimit (50) matching
the descriptor's MaxValue and clamp to that instead.
* fix: cancel batch moves on progress stream failure
Derive a cancellable batchCtx from the caller's ctx. If
sender.SendProgress returns an error (client disconnect, context
cancelled), capture it, skip further sends, and cancel batchCtx so
in-flight moves abort via their propagated context rather than running
blind to completion.
* fix: bound cleanup timeout and validate batch move fields
- Use a 30-second timeout for the deferred markVolumeWritable cleanup
instead of context.Background() which can block indefinitely if the
volume server is unreachable
- Validate required fields (VolumeID, SourceNode, TargetNode) before
appending moves to a batch proposal, skipping invalid entries
- Fall back to a single-move proposal when filtering leaves only one
valid move in a batch
* fix: cancel task execution on SendProgress stream failure
All handler progress callbacks previously ignored SendProgress errors,
allowing tasks to continue executing after the client disconnected.
Now each handler creates a derived cancellable context and cancels it
on the first SendProgress error, stopping the in-flight task promptly.
Handlers fixed: erasure_coding, vacuum, volume_balance (single-move),
and admin_script (breaks command loop on send failure).
* fix: validate batch moves before scheduling in executeBatchMoves
Reject empty batches, enforce a hard upper bound (100 moves), and
filter out nil or incomplete move specs (missing source/target/volume)
before allocating progress tracking and launching goroutines.
* test: add batch balance execution integration test
Tests the batch move path with 3 volumes, max concurrency 2, using
fake volume servers. Verifies all moves complete with correct readonly,
copy, tail, and delete RPC counts.
* test: add MarkWritableCount and ReadFileStatusCount accessors
Expose the markWritableCalls and readFileStatusCalls counters on the
fake volume server, following the existing MarkReadonlyCount pattern.
* fix: oscillation guard uses global effective counts for heterogeneous capacity
The oscillation guard (max-min <= 1) previously used maxServer/minServer
which are determined by utilization ratio. With heterogeneous capacity,
maxServer by utilization can have fewer raw volumes than minServer,
producing a negative diff and incorrectly triggering the guard.
Now scans all servers' effective counts to find the true global max/min
volume counts, so the guard works correctly regardless of whether
utilization-based or raw-count balancing is used.
* fix: admin script handler breaks outer loop on SendProgress failure
The break on SendProgress error inside the shell.Commands scan only
exited the inner loop, letting the outer command loop continue
executing commands on a broken stream. Use a sendBroken flag to
propagate the break to the outer execCommands loop.
* fix: paginate bucket listing in Admin UI to show all buckets
The Admin UI's GetS3Buckets() had a hardcoded Limit of 1000 in the
ListEntries request, causing the Total Buckets count to cap at 1000
even when more buckets exist. This adds pagination to iterate through
all buckets by continuing from the last entry name when a full page
is returned.
Fixesseaweedfs/seaweedfs#8564
* feat: add server-side pagination and sorting to S3 buckets page
Add pagination controls, page size selector, and sortable column
headers to the Admin UI's Object Store buckets page, following the
same pattern used by the Cluster Volumes page. This ensures the UI
remains responsive with thousands of buckets.
- Add CurrentPage, TotalPages, PageSize, SortBy, SortOrder to S3BucketsData
- Accept page/pageSize/sortBy/sortOrder query params in ShowS3Buckets handler
- Sort buckets by name, owner, created, objects, logical/physical size
- Paginate results server-side (default 100 per page)
- Add pagination nav, page size dropdown, and sort indicators to template
* Update s3_buckets_templ.go
* Update object_store_users_templ.go
* fix: use errors.Is(err, io.EOF) instead of string comparison
Replace brittle err.Error() == "EOF" string comparison with idiomatic
errors.Is(err, io.EOF) for checking stream end in bucket listing.
* fix: address PR review findings for bucket pagination
- Clamp page to totalPages when page exceeds total, preventing empty
results with misleading pagination state
- Fix sort comparator to use explicit ascending/descending comparisons
with a name tie-breaker, satisfying strict weak ordering for sort.Slice
- Capture SnapshotTsNs from first ListEntries response and pass it to
subsequent requests for consistent pagination across pages
- Replace non-focusable <th onclick> sort headers with <a> tags and
reuse getSortIcon, matching the cluster_volumes accessibility pattern
- Change exportBucketList() to fetch all buckets from /api/s3/buckets
instead of scraping DOM rows (which now only contain the current page)
* admin: fix Max Volumes column always showing 0
GetClusterVolumeServers() computed DiskCapacity from
diskInfo.MaxVolumeCount but never populated the MaxVolumes field
on the VolumeServer struct, causing the column to always display 0.
* balance: use utilization ratio for source server selection
The balancer selected the source server (to move volumes FROM) by raw
volume count. In clusters with heterogeneous MaxVolumeCount settings,
the server with the highest capacity naturally holds the most volumes
and was always picked as the source, even when it had the lowest
utilization ratio.
Change source selection and imbalance calculation to use utilization
ratio (effectiveCount / maxVolumeCount) so servers are compared by how
full they are relative to their capacity, not by absolute volume count.
This matches how destination scoring already works via
calculateBalanceScore().
* weed/server: fix dropped error
* Removed the redundant check.
