Lost pool config

[BenHD]

Hi FreeNAS Forum,

I used to run FreeNAS on a HP NL54 with a USB Stick and two 4TB SATA Drives for around 6 months. Everything worked like charm until the USB Stick failed.

So I go myself a SSD for the OS and reinstalled FreeNAS 9.2.1.9 hoping to find a easy way to recover RAID1 on the two SATA drives.

Code:

[root@freenas] ~# zpool create storage /dev/ada0p2
invalid vdev specification
use '-f' to override the following errors:
/dev/ada0p2 is part of potentially active pool 'main'

So it seems that I used to have a pool called "main".

Here is a list of

Code:

camcontrol devlist
<WDC WD40EZRX-00SPEB0 80.00A80>    at scbus0 target 0 lun 0 (pass0,ada0)
<WDC WD40EZRX-00SPEB0 80.00A80>    at scbus1 target 0 lun 0 (pass1,ada1)
<INTEL SSDSA2CT040G3 4PC10362>     at scbus4 target 1 lun 0 (pass2,ada2)

Code:

How do I move forward from here? Is there a easy way to reassamble the RAID without loosing data? If not is there a way to mount the data so that I can backup to another NAS/USB Drive?

Thanks a lot,
Ben

Restore your config file and do an auto-import from the GUI, and you should be set. If not, do zpool import and zpool status from the CLI, and post the results.

And don't go trying to create pools from the CLI! That's how you lose pools later!

Hi,

thanks for you help.
Unfortunately I never bothered to to save the config file.

Here is the output

Code:

[root@avalon] ~# zpool import
   pool: main
     id: 8248162094320889574
  state: ONLINE
 action: The pool can be imported using its name or numeric identifier.
 config:

    main                                            ONLINE
     mirror-0                                      ONLINE
       gptid/7dc3ac3e-e691-11e3-88d1-9cb654045407  ONLINE
       gptid/7ecb901a-e691-11e3-88d1-9cb654045407  ONLINE
[root@avalon] ~# zpool status
no pools available

So I tried to import the pool with "zpool import main". That's still running for 20 Minutes.
Is there anything I can do besides wait on "zpool import main" to return?

Thanks,
Ben

Yes.. you can not use the zpool import main command because the manual *never* tells you to do that. You should be using the WebGUI.

Hi, I tried "Auto Import Volume" via the WebGUI but that Dialog hangs as well as the cli.
Screenshot of last Dialog: http://image.bayimg.com/f5a5e8a84c7fb061b3e11b66ceb06847b0f11e58.jpg
Hangs here: http://image.bayimg.com/848818e6b731d3c6c70dcbbd14ff131143553594.jpg

I couldn't find anything about the WebGUI not working at this stage, that's why I tried running import via the shell.

Any advice?
