Hello all, I have a critical ZFS problem, quick history
I have a production machine which backplane has burnt (litteraly) that
had 2 pools : "applis" & "storage". Those pools are RAIDz1 + 1 spare.
Then we switched to the backup one, all right.
Backup machine is the exact replica of production one, files are rsynced
every night. I needed to reboot it to rename it, so I did. But reboot
failed : zfs panic at boot. following sun's doc, I
moved /etc/zfs/zpool.cache away, and reboot. All fine. Mounted pool
"storage" without problem, but unable to mount pool "applis".
Someone suggested disks were re-labelled, I'm open to all advices, If I
can't get those datas back, all we be lost...
Thanks for reading, and maybe helping.

ZFS)
