On the server with Centos and zfs there are three pools. After the reboot, one pool fell off 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 that this is a physical problem with sdw and sdx screws, or can you somehow bring this raid back to life?

    this is a physical problem with sdw and sdx screws

    sdw - corrupted data
    sdx - not available at all (disabled or out of order)

    can you somehow bring this raid back to life?

    if it fails to “return” the missing sdx, then, judging by the verdict given there:

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

    the only possible solution is to delete the pool and re-create it from the backup.
