ZFS says drive is faulted, does that always mean it needs replacing?
ZFS says drive is faulted, does that always mean it needs replacing?
My weekly zpool scrub came back with this:
pool: blackhole
state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
repaired.

I only got the drive 6 months ago, well within WD's 3 year warranty so I opened a support case, but do errors like this basically always mean the drive is its way out or is it possible to have false positives?
