Volume disappeared

[giox069]

Hi all.

I'm using FreeNAS-8.0.4-RELEASE-p2-x64 (11367). Suddenly all my data disappeared. I think this happened after a power outage.

On the web console, the "alert" yellow icon is flashing. When I click on it I get the message box "WARNING: The volume Volume1 (ZFS) status is " and there are no other characters after the word "is".
In "view all volumes", I can see my two volume paths with "None (Error)", "Error getting available space", "Error getting total space".

Here is the output of some commands given in a ssh console:

Code:

[root@pyprel] ~# zpool status -v
no pools available
[root@pyprel] ~#

Code:

[root@pypyrel] ~# zfs list
no datasets available

What could I do now ?

Thank you

What could I do now ?

Supply more information. Should I assume that Volume1 is a 3 disk, ada0-ada1-ada2, raidz1 array made up of 2Tb local disks?

In "view all volumes", I can see my two volume paths with "None (Error)", "Error getting available space", "Error getting total space".

OK, maybe not? How are these disks connected and do you see all of them?

Code:

camcontrol devlist

zpool import

Thank you for you relpy.
It's a single zfs volume in 3 SATA disks. The second "volume" is a DataSet, see attached image.

Freenas OS is installed on a USB pendrive.

Code:

[root@pyprel] ~# camcontrol devlist
<WDC WD20EARS-00MVWB0 51.0AB51>    at scbus0 target 0 lun 0 (ada0,pass0)
<WDC WD20EARS-00MVWB0 51.0AB51>    at scbus1 target 0 lun 0 (ada1,pass1)
<WDC WD20EARS-00MVWB0 51.0AB51>    at scbus2 target 0 lun 0 (ada2,pass2)
<JetFlash Transcend 8GB 1100>      at scbus6 target 0 lun 0 (da0,pass3)
[root@pyprel] ~# zpool import

Code:

[root@pyprel] ~# zpool import
  pool: Volume1
    id: 9987938208860202107
 state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:

        Volume1     ONLINE
          raidz1    ONLINE
            ada0p2  ONLINE
            ada1p2  ONLINE
            ada2p2  ONLINE
[root@pyprel] ~#

I like the words "The pool can be imported using its name or numeric identifier" :)

What's the next step ?

Thank you again.

I solved the problem with the following sequence of actions:

• Upgraded freenas to 8.2.0
• From web GUI, detached the volume
• zpool import -fF Volume1
• zpool clear Volume1
• reboot
• From web gui: Auto import volume
• Reboot

I don't really understand what happened and what these commands do. But now it works.

I don't really understand what happened and what these commands do. But now it works.

Then I hope the devs or moderators told you to do them!

• Upgraded freenas to 8.2.0
• From web GUI, detached the volume
• zpool import -fF Volume1
• zpool clear Volume1
• reboot
• From web gui: Auto import volume
• Reboot

1. Upgrades to 8.2.0 obviously.
2. This exports the pool and updates the FN8 database that the pool is exported.
3. Imports the pool with the -f, force option, i.e. pools that appear in use, etc. The other -F doesn't do anything until 8.3, afaik.
4. Clears any errors in the pool.
5. reboots ;)
6. Imports the pool and updates the FN8 database.
7. Reboots. :p

Personally, I would run a scrub now if you haven't already.
