    Exclamation ERROR: No system volume found! System services can't work without system volume !

    Hi everyone, and thx for those who will be able to help

    Last week i had some troubles with my NAS. It looked like some troubles with the RAID, so i changed the RAID controller, and i also had 2 degraded disk on my RAID6 volume, that i changed.

    I started to rebuild them, but couldnt pass 51% cause of ECC-errors on a 3rd disk, so i added the option to ignore those errors.

    Then the rebuild worked.

    Now when im booting, i'm getting this error :
    ERROR: No system volume found! System services can't work without system volume !

    my RAID seems working :
    //dssA0019718> info c7

    Run a consistency check on the raid array and see if the previous errors can be repaired.

    let's see if it will help, but i have doubts, because after the rebuild, there was an automatic verify, and it found nothing wrong.
    Is that the good way to check consistency on 3ware controller btw ?

    There is a good chance you will need to restore from backups. Wait and see if there are more repairs. The system volume can be rebuilt if needed.

    If this volume doesnt come back, i dont know what to do...
