What this triage does
Pool state and drive state are separate because a single-drive alert and an inaccessible array carry different risks. Restore verification and mechanical noise determine whether to copy data first or inspect logs.
A RAID rebuild is a sustained full-read workload. This tool does not predict rebuild success; it places stop rules before any automatic repair action when no recoverable copy exists.
Stop conditions: protect data first
- No verified backup exists while the pool is degraded or crashed.
- A disk is missing, noisy, overheating, or smells burnt.
- Multiple drives may be removed before recording bay numbers and drive order.

Menu names and supported procedures vary by vendor and model. This tool does not replace official instructions; its rules are reviewed when sources change.
Next steps
After protecting data, estimate RAID rebuild exposure and review the drive buying checklist.
