Message ID: ZFS-8000-5E

Corrupted device label in non-replicated configuration

Type:	Error
Severity:	Critical
Description:	A device could not be opened due to a missing or invalid device label and no replicas are available.
Automated Response:	No automated response will be taken.
Impact:	The pool is no longer available.

Suggested Action for System Administrator

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://openzfs.github.io/openzfs-docs/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.
