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

  1. #1

    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.

    System volume is a small partition used for storing configuration of most services. If it is corrupted due to hardware problem you will not be able to access the data, even if it is on completely different device.
    Each volume group has its own system volume, so in case one is corrupted you can switch to the other one (if you dont have backup of configuration just create new share/iscsi target with exiting volume to access the data).
    What you should do now is to reinstall the os to make sure boot medium is ok, or boot it from flash drive and switch default volume group to other one to use other system volume.
    If you need more help open a support ticket so support guys can help you.

    I bought this NAS with the system pre-installed. So i didnt receive any media to reinstall.
    I can boot the OS, still, but when i try to access my shares to manage them, it says that there is not system volume.
    I'm only having one volume group.
    right now, im running the "unit verifying" thru the 3ware bios. I don't know if it's the same at the verify thru CLI, but it looks like. It's taking exactly the same time so far... (27% so far).
    i should be done in 5h.
    so, then i can just reboot, go on the webinterface.
    If i go to configuration -> volume managers , i should see the VG0
    but i cant create a new share through configuration->NAS ressources->shares cause it's telling me there that i have no SV or something like that. So how should i create a new share ?
    by the way, if i create a new share, there is no risks that it creates a new SV that will erase my old shares ?
    my support has run out of date, so i doubt they will help me.

    if you dont have other VG create one on single HDD drive until you recover. Create new share, backup the data, then recreate the VG if you dont want support help.
    I bet you can renew your support licence.
