Last week my FreeNAS server began to beep constantly so I rebooted it through the webgui. When the machine finished booting I logged back in to the webgui and I noted that my zpool (Raidz) was faulted. Most of the data on this pool is replaceable but I had some pictures on this pool that were not backed up that I would really like to recover. At the time that the machine started to beep I was verifying a torrent and streaming a movie.
Here is a little more info about my setup: -------------------------------------------- FreeNAS 0.7.1 Shere (revision 4997) intel pentium 4 tyan s5161 2Gb ram adaptec aar-21610sa 1x 250Gb maxtor boot drive/storage 6x 1tb WD drives in raidz (pool name Raidz) ZFS filesystem version 6 ZFS storage pool version 6 -------------------------------------------- Commands I tried and their output: freenas:~# zpool import no pools available to import freenas:~# zpool status -v pool: Raidz state: FAULTED status: The pool metadata is corrupted and the pool cannot be opened. action: Destroy and re-create the pool from a backup source. see: http://www.sun.com/msg/ZFS-8000-CS scrub: none requested config: NAME STATE READ WRITE CKSUM Raidz FAULTED 0 0 6 corrupted data raidz1 FAULTED 0 0 6 corrupted data aacdu0 ONLINE 0 0 0 aacdu1 ONLINE 0 0 0 aacdu2 ONLINE 0 0 0 aacdu3 ONLINE 0 0 0 aacdu4 ONLINE 0 0 0 aacdu5 ONLINE 0 0 0 freenas:~# zpool import -f no pools available to import freenas:~# zpool import -f Raidz cannot import 'Raidz': no such pool available ==================================================== I transfered the drives to another motherboard (asus, core2 duo, 4Gb ram) and booted freebsd 8.1RC1 with ZFSv14.

I am not sure what any of this means and fortunately I didn't record the outputs. I can redo this if necessary. I then booted opensolaris 2009.06 and 4 out of the 6 disks showed corrupt data when I did "zpool import." When I tried to import the pool it couldn't but I can't remember the output. I have never used opensolaris and could not ssh into it to record the outputs. With "zpool import -f Raidz" opensolaris did not crash but wouldn't import either.
