Cant restore zfs volume.

[esbleha]

After updating to 11.1 U7 the server couldn't start the server, it would freeze on startup.
After that loaded in to older install i had from initially installing the server, then i deleted the updated boot option because i thought that i fixed the problem.
In fact the i have rolled back all the settings and my zfs volumes disappeared.

Is there a way to restore my zfs volumes after that and restoring the information?

 

[esbleha]

Anyone? Will i get my files back ever?

Can you boot into the system? If so, what is the full output of zpool status ?

 

[esbleha]

[root@freenas ~zpool status

Which volumes were you expecting to see? The temp pool is online.

 

[esbleha]

I had 3 pools:
Main
torrent
temp

 

[dlavigne]

Were they all one disk pools with no redundancy? If so, it is possible those disks died (taking the data with them). Hard to tell without more info about your hardware and what caused the freeze.

main was 3 2TB discs
torrent was 1 320 GB disc

It probably has the pools marked as in use by another NAS. You may need to just run a "zpool import", but first check to see if the disks are attached.

Are you using an HBA, or motherboard SATA ports? Try seeing if the disks are even recognized by the kernel, ala:

ls -l /dev/ada*

or

ls -l /dev/da*

If you can locate those, you should be able to query the drives using "smartctl -a <dev>" and figure out if they've failed.

I can see the drives. even in gui. the thing is that it apears as if i have fresh install of freenas. because i deleted the corupt boot option after bad update

Any chance you have a saved copy of your config? You should be able to restore it and recover the old configuration. If not, you can still import the pools using "zpool import".

zpool import does nothing. the fist time it let me import the temp only

 

[rvassar]

The pools are tagged as owned by the NAS instance you deleted. Try "zpool import -f".

I'm running short of ideas... Can you pull the smartctl info? "smartctl -a <dev>"

You're going to need to run a self test on that disk. "smartctl -t short <dev>" and then wait the test time and pull those stats again. When you post the result, please wrap the pasted text in "code" tags. It makes it much easier to read here on the forums.
