Recovery of data (needing help)

[Deano]

I'm hoping someone can provide some help.

I've been running FreeNAS for about 2 years on the same machine. No problems until the day before yesterday. We had a power failure and when power got restored, the FreeNAS machine didn't come back up (could not login via GUI or access via network files).

I put a keyboard and monitor on the machine and noticed it hung during boot. I tried to upgrade to the new FreeNAS system (writting over the USB stick) and no change. I then (and maybe here's where I'm in trouble) took the original CD (version 8.0) and reinstalled to the USB (fresh install).

I can get to FreeNAS via the web (another machine), but cannot restore data drives. I have 2 2TB WD drives. I can see them in FreeNAS (console window), but can't get them back into service.

I need some help....please. "zpool status" returns nothing. The drives were setup using ZFS. I can see the two drives (ada0 and ada1).

try "zpool import". That won't import the pool, but it will show us a little about the status of your pool.

 

[Deano]

no pools to import

 

[cyberjock]

It should return either nothing at all or some info. It doesn't say "no pools to import". If it had some info, I'd like a paste of that.

Additionally, post the output of:

camcontrol devlist
gpart status
gpart list

Hope that helps.....

Actually if the two "ZFS" lines were in bright white, that wasn't a response, they were kernel messages. The use of an older ZFS might not be a good idea. Older ZFS can't import a newer pool. New ZFS can import old pools.

 

[Deano]

Yes, the response was in "bright white" lettering.

BTW, I am using FreeNAS-8.0.4-RELEASE-x64 (10351)

 

[Deano]

Just a bump. I've come to the conclusion that I may have lost everything, but I still have the drives and USB stick set aside (I've not resorted to a Windows box on the network with a shared drive for backup).

I'd like to use the drives that were on the FreeNAS box, but am still hopeful that I might be able to retrieve the data. At this point, all I want to do is get the data (in any way / shape).

Any help by someone would be most appreciated.
