How do you get the raidz1-0 bullet back in zfs?



  • There are three bullets on the Centos and zfs server. After the rebuttal, one bullet fell down and the status shows this:

    zpool status -x
          pool: tank2
         state: UNAVAIL
        status: One or more devices could not be used because 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: http://zfsonlinux.org/msg/ZFS-8000-5E
          scan: none requested
        config:
    
            NAME        STATE     READ WRITE CKSUM
            tank2       UNAVAIL      0     0     0  insufficient replicas
              raidz1-0  UNAVAIL      0     0     0  insufficient replicas
                sdq     ONLINE       0     0     0
                sdr     ONLINE       0     0     0
                sds     ONLINE       0     0     0
                sdt     ONLINE       0     0     0
                sdu     ONLINE       0     0     0
                sdv     ONLINE       0     0     0
                sdw     FAULTED      0     0     0  corrupted data
                sdx     UNAVAIL      0     0     0
    

    I understand it's a physical problem with sdw and sdx rifles, or is it possible to get this raid back to life?



  • It's a physical problem with sdw and sdx rifles.

    sdw - data damaged
    sdx - unavailable at all.

    Can we get this raid back to life somehow?

    If it is not possible to " reverse " the missing sdx, it is the verdict that has been given that:

    action: Destroy and re-create the pool from
            a backup source.
    

    The only possible solution is to remove the bullet and re-create the backup.
