    Can you provide the steps that you performed so far?

     

    Did you physically replace the bad disk and use the zpool replace command?

     

    Thanks, Cindy

    hi

    i tried to detach the disk c1t0d6 first first but it's not working

    # zpool detach eniq_sp_1  c1t0d6

    cannot detach : no valid replicas

    then  the second step :

    1. shutdown the system

    2. replace the disk on the storage

    3. start the system (the zpool are mounted coreectly but Degraded) c1t0d6 unavailble

    4. # zpool replace  eniq_sp_1  c1t0d6

    that's all

     

    thank you for your response

    Hi,

     

    Something else went wrong on this system and with this pool because the other device resilvered as well

    and you have one corrupt file.

     

    Next, try to clear the pool errors, like this:

     

    # zpool clear eniq_sp_1

     

    See if that clears the pool errors.

    Next, you need to scrub the pool to make sure nothing else is amiss.

    After the scrub completes, see if zpool status is clear. If not, you might need to remove the corrupted file.

     

    Thanks, Cindy

    thank you Cindy

    but after doing( (zpool clear eniq_sp_1)  --> then zpool start synchronization automatically

    and (zpool scrub eniq_sp_1) display the same file error and the same state of the Zpool

     

     

    Thanks,

    Taieb

    Sorry, I don't know what you mean by zpool start synchronization...

     

    Are you saying that the resilver of the failed disk starts again or all the disks resilver again?

     

    Thanks, Cindy

    yes, after clear the zpool, all the disks resilver again

    and when we try to backup file systems, 

    this backup of the file   eniq_sp_1/dwh_main_dbspace@VIRTUAL_BACKUP_SNAP:/dbspace_dir_1/main_41.iq

    can't be terminated successfully

    hi

    please tel me if the only solution is to destroy the Zpool

    and recreate it and restore data

    thanks

    I think there are other solutions than destroying the pool, but if you wish, this is an option.

     

    You might try removing the corrupted file with the rm command.

    Another idea is to try detaching this disk if the other disk in the mirrored pair is stable.

     

    Thanks, Cindy
