Pool Missing

Originated as a missing pool on startup, read a few posts about similar but cannot find anything that directly relates.

Amateur but I don't think I have a backup of the pool information, anything relating to creating a new pool wipes the disks which I would obviously like to avoid.

Can anyone offer some advice on anything else to check next?

Virtual FreeNas 11.2-RC2 running on ESXI server
Adaptec raid controller for 4 x 3tb disks (showing as 8tb drive)
(not sure what other information is useful or relevant).

So you are missing your main pool? Run zpool import from a FN host terminal see if that grabs it.

As far as the corrupt files, id grab a config backup from the GUI, then you might think about a reinstall to fix the errors current version is 11.2-U7, you are running a pretty old RC version.

You shouldn't do that with FreeNAS whether it is bare metal or virtual. FreeNAS needs direct access to the physical disks.

What Chris said.
Looks to me like the Adaptec has the four drives in a RAID array and then presented that single virtual drive to FreeNAS.
FreeNAS thinks it has a pool consisting of just one drive; therefore, you lose almost all the benefits of ZFS.

Yes, I will look to change it after, but for not I just wish to attempt to restore what I had.

zpool import FREENAS advises
'cannot import 'FREENAS': a pool with that name is already created/imported, and no additional pools with that name were found.

However, via the GUI I still have no pools.

 

[Chris Moore]

Based on the content of your post, the pool is there it may simply be the network share that's not working right

 

[daftfool]

Thanks again I will investigate this. However first check doesn't look promising as there doesn't appear to be any network sharing set up :S

Looks like the pool and network share configuration has been wiped, but I don't know how to restore that without wiping the disks. I will continue looking.

Update *All Fixed*

Re-read insturctions from previously and reapplied after a night sleep thinking about it.

Exported from CLI, imported via WEB GUI, which made the volume available to import.

Imported the volume, and then set up a new network share.

Now to backup the backup and get rid of the hardware raid.

Thanks for the help.
