Adds a fault-tolerance suite that verifies read/write behavior under
drive and node loss against the erasure-coding contract and snapshots
health-endpoint responses at every degradation tier. Scenarios derived
from product source (default_parity_count, erasure set sizing):
- A: single-node 4 drives (EC:2, read quorum 2): hide 1/2/3 drives
- B: multi-node 4x1 (one set of 4, EC:2): stop 1/2/3 nodes
- C: multi-node 4x4 (one set of 16, EC:4, read quorum 12): 1 node down
lands exactly on the read-quorum boundary; 2 nodes down breaks it
- C2: multi-node 4x4 with RUSTFS_STORAGE_CLASS_STANDARD=EC:8 (read
quorum 8, write quorum 9, lock majority 9): 2 nodes down puts reads
inside the reported divergence window (read quorum met while the
lock majority is broken)
By default a reads-refused-despite-met-read-quorum observation is
reported as known-divergence without failing the suite; the strict
input escalates it. Chain order becomes:
upgrade -> s3 -> kms -> tier -> storage -> heal -> pool -> security ->
replication -> fault-tolerance -> performance.
- New RustFS Replication Test workflow (rustfs-replication-test.yml):
standalone workflow_dispatch (suite selector bucket/site/all) and
repository_dispatch rustfs-chain-replication; runs on the shared
smoke-testing runner under the shared functional concurrency group.
- Suite never fails the workflow (continue-on-error): failures are filed
as redacted issues in rustfs/backlog (deduped per run) and the report is
uploaded to rustfs/dashboard functional-reports/replication/<date>.md.
- Security now hands off to Replication, making it the tenth and final
link: upgrade -> s3 -> kms -> tier -> storage -> heal -> pool ->
security -> replication (performance stays parallel on pf-testing).
- Depends on rustfs/auto-testing#27 (rustfs-replication-test.sh).

Problem: the nightly functional chain has not completed end-to-end.
Evidence from recent runs:
- workflow_run events are fire-and-forget: after KMS finished at 17:09Z
on 8/31 no tier run was created; rustfs-storage-test.yml has never run.
- 'if: conclusion == success' gates skip downstream suites on any
failure (security was skipped after pool failed on 9/1 01:48Z).
- rustfs-pool-expand-test.yml embedded a heal pass without
continue-on-error, so a heal failure failed the whole workflow.
Fixes:
- Add rustfs-functional-chain.yml: entry point that dispatches the first
suite via repository_dispatch; each suite hands off to the next with an
explicit, re-drivable API call instead of workflow_run triggers.
- Split heal out of the pool workflow (renamed to RustFS Pool Expansion
Test): heal now runs exactly once per chain, in rustfs-heal-test.yml
(storage -> heal -> pool).
- Every suite job gets continue-on-error so a failing test never fails
the workflow; failures are filed as issues in rustfs/backlog (report
+ redacted log tail) and the chain moves on.
- Clone rustfs/auto-testing with the PF token via 'gh repo clone' plus a
5-attempt retry loop (transient clone failures aborted whole suites).
- Stop rewriting functional/index.html from every suite (divergent
copies raced each other with stale SHAs); the canonical index now
lives in the dashboard repo.
- Standalone workflow_dispatch runs are unchanged and never forward the
chain; performance runs on its own runner, dispatched in parallel.
