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

[Franck67]

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 :

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.

[Franck67]

i have no backups.
If this volume doesnt come back, i dont know what to do...

[Franck67]

and concretely, at the end of this test, what should i do ? just reboot my NAS and it should work ? or some others commands to run ?
