Description

Dear All,

While I realise this is similar to previous tickets. 1364, 1889, 490 etc. I haven't quite got the answer I am after.

Spec:
Dell [[PowerEdge]] R510, 1 CPU, 16GB RAM
boot:2GB USB drive Data:8x2GB in RAIDZ2
[[FreeNAS]] 8.2? (or the latest available as of November 2012)

After a power outage, the machine reboots with:

Trying to mount root from UFS:/dev/ufs/FreeNASs1a
mount: /dev/ufs/FreeNASs3 : No such file or directory
mount -o ro /dev/ufs/FreeNASs3 /conf/default/etc failed: dropping into /bin/sh

I understand this is most likely due to a failing / failed USB drive. What are my options here?
Can I do a repair install / upgrade on the existing boot USB device?
Can I clone the existing USB device and repair / replace the damaged corrupt areas?
Do I have to bin the current boot device and Install afresh?

How do these options leave my data (around 7TB of backups)?
What further troubleshooting information gathering should I be looking at doing?

As an aside what are the 4 partitions on a [[FreeNAS]] boot device each contain? I have only been able to look inside ...s1a and that seems to have a file system. I don't seem to be able to mount the others.
(Sorry am new to the BSD way of naming things)

Regards,

Jim
