pingqiuandClaude Opus 4.6 25ede892b4 doc: external failure taxonomy — 20 real bugs from Ceph/DRBD/Mayastor/Longhorn
Catalogs production failures organized by semantic class:
- Membership/liveness misjudgment (4 cases)
- Recovery decision error (3 cases)
- Completion/durability illusion (4 cases)
- Ordering/race conditions (4 cases)
- Background work corrupts semantics (3 cases)

Each entry maps to V2 exposure and V3 prevention rules.
Includes "Would V2 Have This Bug?" self-audit checklist.

sw-block

Private WAL V2 and standalone block-service workspace.

Purpose:

  • keep WAL V2 design/prototype work isolated from WAL V1 production code in weed/storage/blockvol
  • allow private design notes and experiments to evolve without polluting V1 delivery paths
  • keep the future standalone sw-block product structure clean enough to split into a separate repo later if needed

Suggested layout:

  • design/: shared V2 design docs
  • prototype/: code prototypes and experiments
  • .private/: private notes, phase development, roadmap, and non-public working material

Repository direction:

  • current state: sw-block/ is an isolated workspace inside seaweedfs
  • likely future state: sw-block becomes a standalone sibling repo/product
  • design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
