For an active pool
If this error was encountered while running 'zpool import', please see the section below. Otherwise, run 'zpool status -x' to determine which pool has experienced a failure:
# zpool status -x pool: test state: FAULTED status: One or more devices could not be used because the the label is missing or invalid. There are insufficient replicas for the pool to continue functioning. action: Destroy and re-create the pool from a backup source. see: https://zfsonlinux.org/msg/ZFS-8000-5E scrub: none requested config: NAME STATE READ WRITE CKSUM test FAULTED 0 0 0 insufficient replicas c0t0d0 FAULTED 0 0 0 corrupted data c0t0d1 ONLINE 0 0 0 errors: No known data errors
The device listed as FAULTED with 'corrupted data' cannot be opened due to a corrupt label. ZFS will be unable to use the pool, and all data within the pool is irrevocably lost. The pool must be destroyed and recreated from an appropriate backup source. Using replicated configurations will prevent this from happening in the future.
For an exported pool
If this error is encountered during 'zpool import', the action is the same. The pool cannot be imported - all data is lost and must be restored from an appropriate backup source.
