From 9acd187587e3dd2b46edbfb50acfa50ac4793179 Mon Sep 17 00:00:00 2001 From: Ping Qiu Date: Sat, 7 Mar 2026 21:30:14 -0800 Subject: [PATCH] feat: Phase 8 complete -- CP8-5 stability gate, lease grant fix, Docker e2e, 13 chaos scenarios Phase 8 closes with all 6 checkpoints done (CP8-1 through CP8-5 + CP8-3-1): - CP8-5: 12/12 enterprise QA scenarios PASS on real hardware (m01/M02) - Master-authoritative lease grants (BUG-CP85-11): master renews primary write leases on every heartbeat response, replacing retain-until-confirmed assignment queue semantics that caused 30s lease expiry - Post-rebuild WAL shipping gap fix (BUG-CP85-1): syncLSNAfterRebuild advances replica nextLSN so WAL entries are accepted after rebuild - Block heartbeat startup race fix (BUG-CP85-10): dynamic blockService check on each tick instead of one-shot at loop start - 8 new tests: 4 engine lease grant + 4 registry lease grant - 13 new YAML scenarios: chaos (kill-loop, partition, disk-full), database integrity (sqlite crash, ext4 fsck), perf baseline, metrics verify, snapshot stress, expand-failover, session storm, role flap, 24h soak - 12 new testrunner actions (database, fsck, grep_log, write_loop_bg, stop_bg, assert_metric_gt/eq/lt) + phase repeat support - Docker compose setup + getting-started guide for block storage users - 960+ cumulative unit tests, 24 YAML scenarios Co-Authored-By: Claude Opus 4.6 --- docker/compose/BLOCK_GETTING_STARTED.md | 247 ++++++++++ docker/compose/local-block-compose.yml | 38 ++ docker/entrypoint.sh | 105 +---- weed/command/volume.go | 16 +- weed/server/block_heartbeat_loop_test.go | 2 +- weed/server/master_block_registry.go | 49 ++ weed/server/master_block_registry_test.go | 119 +++++ weed/server/master_grpc_server.go | 27 +- weed/server/volume_grpc_block_test.go | 2 +- weed/server/volume_grpc_client_to_master.go | 23 +- weed/server/volume_server_block.go | 5 +- weed/server/volume_server_block_test.go | 4 +- .../storage/blockvol/block_heartbeat_proto.go | 1 + weed/storage/blockvol/blockvol.go | 1 + weed/storage/blockvol/blockvol_test.go | 13 +- .../cmd/iscsi-target/demo-ha-windows.ps1 | 316 +++++++++++++ weed/storage/blockvol/lease_grant_test.go | 170 +++++++ weed/storage/blockvol/promotion.go | 3 + weed/storage/blockvol/qa_phase4a_cp3_test.go | 13 +- weed/storage/blockvol/rebuild.go | 32 ++ .../blockvol/testrunner/actions/block.go | 18 +- .../blockvol/testrunner/actions/database.go | 132 ++++++ .../testrunner/actions/devops_test.go | 14 +- .../storage/blockvol/testrunner/actions/io.go | 60 +++ .../blockvol/testrunner/actions/metrics.go | 82 ++++ .../blockvol/testrunner/actions/register.go | 1 + .../blockvol/testrunner/actions/system.go | 85 ++++ weed/storage/blockvol/testrunner/engine.go | 27 +- .../blockvol/testrunner/engine_test.go | 96 ++++ .../blockvol/testrunner/infra/fault.go | 6 +- weed/storage/blockvol/testrunner/parser.go | 3 + .../scenarios/cp85-chaos-disk-full.yaml | 127 ++++++ .../scenarios/cp85-chaos-partition.yaml | 143 ++++++ .../cp85-chaos-primary-kill-loop.yaml | 426 ++++++++++++++++++ .../cp85-chaos-replica-kill-loop.yaml | 325 +++++++++++++ .../scenarios/cp85-db-ext4-fsck.yaml | 154 +++++++ .../scenarios/cp85-db-sqlite-crash.yaml | 341 ++++++++++++++ .../scenarios/cp85-expand-failover.yaml | 153 +++++++ .../scenarios/cp85-metrics-verify.yaml | 137 ++++++ .../scenarios/cp85-perf-baseline.yaml | 103 +++++ .../testrunner/scenarios/cp85-role-flap.yaml | 355 +++++++++++++++ .../scenarios/cp85-session-storm.yaml | 86 ++++ .../scenarios/cp85-snapshot-stress.yaml | 132 ++++++ .../testrunner/scenarios/cp85-soak-24h.yaml | 167 +++++++ weed/storage/blockvol/testrunner/types.go | 1 + 45 files changed, 4206 insertions(+), 154 deletions(-) create mode 100644 docker/compose/BLOCK_GETTING_STARTED.md create mode 100644 docker/compose/local-block-compose.yml create mode 100644 weed/storage/blockvol/iscsi/cmd/iscsi-target/demo-ha-windows.ps1 create mode 100644 weed/storage/blockvol/lease_grant_test.go create mode 100644 weed/storage/blockvol/testrunner/actions/database.go create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-chaos-disk-full.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-chaos-partition.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-chaos-primary-kill-loop.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-chaos-replica-kill-loop.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-db-ext4-fsck.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-db-sqlite-crash.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-expand-failover.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-metrics-verify.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-perf-baseline.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-role-flap.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-session-storm.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-snapshot-stress.yaml create mode 100644 weed/storage/blockvol/testrunner/scenarios/cp85-soak-24h.yaml diff --git a/docker/compose/BLOCK_GETTING_STARTED.md b/docker/compose/BLOCK_GETTING_STARTED.md new file mode 100644 index 000000000..894dad9c3 --- /dev/null +++ b/docker/compose/BLOCK_GETTING_STARTED.md @@ -0,0 +1,247 @@ +# SeaweedFS Block Storage -- Getting Started + +Block storage exposes SeaweedFS volumes as `/dev/sdX` block devices via iSCSI. +You can format them with ext4/xfs, mount them, and use them like any disk. + +## Prerequisites + +- Linux host with `open-iscsi` installed +- Docker with compose plugin (`docker compose`) + +```bash +# Install iSCSI initiator (Ubuntu/Debian) +sudo apt-get install -y open-iscsi + +# Verify +sudo systemctl start iscsid +``` + +## Quick Start (5 minutes) + +### 1.
