IB-health-aware placement

  • Monitors every configured server IB rail through sysfs before each MDS heartbeat.
  • Removes a server from the placement ring immediately when any configured rail is unhealthy.
  • Restores ring eligibility after three consecutive healthy samples.
  • Keeps degraded members visible in dfkvctl topology with per-device port and physical-state detail.
  • Adds MDS gauges for ring-eligible and degraded nodes.

Compatibility

The membership health payload is append-only; older decoders ignore the extension. Existing clusters remain eligible when health is absent.

Verification
