chrislu	85ad2e9a13	improve: implement gRPC-aware retry for FilerClient volume lookups The previous implementation used util.Retry which only retries errors containing the string "transport". This is insufficient for handling the full range of transient gRPC errors. Changes: 1. Added isRetryableGrpcError() to properly inspect gRPC status codes - Retries: Unavailable, DeadlineExceeded, ResourceExhausted, Aborted - Falls back to string matching for non-gRPC network errors 2. Replaced util.Retry with custom retry loop - 3 attempts with exponential backoff (1s, 1.5s, 2.25s) - Tries all N filers on each attempt (N*3 total attempts max) - Fast-fails on non-retryable errors (NotFound, PermissionDenied, etc.) 3. Improved logging - Shows both filer attempt (x/N) and retry attempt (y/3) - Logs retry reason and wait time for debugging Benefits: - Better handling of transient gRPC failures (server restarts, load spikes) - Faster failure for permanent errors (no wasted retries) - More informative logs for troubleshooting - Maintains existing HA failover across multiple filers Example: If all 3 filers return Unavailable (server overload): - Attempt 1: try all 3 filers, wait 1s - Attempt 2: try all 3 filers, wait 1.5s - Attempt 3: try all 3 filers, fail Example: If filer returns NotFound (volume doesn't exist): - Attempt 1: try all 3 filers, fast-fail (no retry)	2 weeks ago
chrislu	1601a4133a	improve: address remaining code review findings 1. Lazy initialize FilerClient in mount for proxy-only setups - Only create FilerClient when VolumeServerAccess != "filerProxy" - Avoids wasted work when all reads proxy through filer - filerClient is nil for proxy mode, initialized for direct access 2. Fix inaccurate deprecation comment in filer.LookupFn - Updated comment to reflect current behavior (10k bounded cache) - Removed claim of "unbounded growth" after adding size limit - Still directs new code to wdclient.FilerClient for better features 3. Audit all MasterClient usages for KeepConnectedToMaster - Verified all production callers start KeepConnectedToMaster early - Filer, Shell, Master, Broker, Benchmark, Admin all correct - IAM creates MasterClient but never uses it (harmless) - Test code doesn't need KeepConnectedToMaster (mocks) All callers properly follow the initialization pattern documented in GetMaster(), preventing unexpected blocking or timeouts.	2 weeks ago
chrislu	71f8a6e189	fix: handle partial results correctly in LookupVolumeIdsWithFallback callers Two callers were discarding partial results by checking err before processing the result map. While these are currently single-volume lookups (so partial results aren't possible), the code was fragile and would break if we ever batched multiple volumes together. Changes: - Check result map FIRST, then conditionally check error - If volume is found in result, use it (ignore errors about other volumes) - If volume is NOT found and err != nil, include error context with %w - Add defensive comments explaining the pattern for future maintainers This makes the code: 1. Correct for future batched lookups 2. More informative (preserves underlying error details) 3. Consistent with filer_grpc_server.go which already handles this correctly Example: If looking up ["1", "2", "999"] and only 999 fails, callers looking for volumes 1 or 2 will succeed instead of failing unnecessarily.	2 weeks ago
chrislu	01b9b68ac5	fix: FilerClient supports multiple filer addresses for high availability Critical fix: FilerClient now accepts []ServerAddress instead of single address - Prevents mount failure when first filer is down (regression fix) - Implements automatic failover to remaining filers - Uses round-robin with atomic index tracking (same pattern as WFS.WithFilerClient) - Retries all configured filers before giving up - Updates successful filer index for future requests Changes: - NewFilerClient([]pb.ServerAddress, ...) instead of (pb.ServerAddress, ...) - filerVolumeProvider references FilerClient for failover access - LookupVolumeIds tries all filers with util.Retry pattern - Mount passes all option.FilerAddresses for HA - S3 wraps single filer in slice for API consistency This restores the high availability that existed in the old implementation where mount would automatically failover between configured filers.	2 weeks ago
chrislu	5a1eed0835	refactor: mount uses FilerClient for efficient volume location caching - Add configurable vidMap cache size (default: 5 historical snapshots) - Add FilerClientOption struct for clean configuration * GrpcTimeout: default 5 seconds (prevents hanging requests) * UrlPreference: PreferUrl or PreferPublicUrl * CacheSize: number of historical vidMap snapshots (for volume moves) - NewFilerClient uses option struct for better API extensibility - Improved error handling in filerVolumeProvider.LookupVolumeIds: * Distinguish genuine 'not found' from communication failures * Log volumes missing from filer response * Return proper error context with volume count * Document that filer Locations lacks Error field (unlike master) - FilerClient.GetLookupFileIdFunction() handles URL preference automatically - Mount (WFS) creates FilerClient with appropriate options - Benefits for weed mount: * Singleflight: Deduplicates concurrent volume lookups * Cache history: Old volume locations available briefly when volumes move * Configurable cache depth: Tune for different deployment environments * Battle-tested vidMap cache with cache chain * Better concurrency handling with timeout protection * Improved error visibility and debugging - Old filer.LookupFn() kept for backward compatibility - Performance improvement for mount operations with high concurrency	2 weeks ago
