Hi All,
I am looking at a friends FreeNAS setup which is facing some issues. He has x4 drives setup in a RAID5 type ZFS configuration. One of the drives seems to have completely failed (it can't even be detected by the BIOS).
However the real issue is that FreeNAS cannot see the ZFS volume despite being able to see the remaining x3 disks. In the GUI it simply says "0 Error". Here are some command outputs which may or may not be useful but can anybody recommend any suitable next steps, I would really like to restore the volume with the remaining disks!
Thanks!
