Hi,
I have a problem with ZFS filesystem on array. ZFS was created
by Solaris 10 U2. Some glitches with array made it panic
Solaris on boot. I've installed snv63 (as snv60 contains some
important fixes), systems boots but kernel panic when
I try to import pool. This is with zfs_recover=1.
Configuration is as follows (on snv63):
# zpool import
pool: macierz
id: 15960555323673164597
state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit 'zpool upgrade'.
config:
macierz ONLINE
c2t0d0 ONLINE
c2t1d0 ONLINE
c2t2d0 ONLINE
c2t3d0 ONLINE
Those are 1,8TB logical volumes exported by array.
And the panic:
Loading modules: [ unix genunix specfs dtrace cpu.AuthenticAMD.15 uppc
pcplusmp scsi_vhci ufs ip hook neti sctp arp usba fctl lofs zfs random
md cpc crypto fcip fcp logindmux ptm ipc ]
::status

I've uploaded crash dump here:
http://www.crocom.com.pl/~tomek/boraks-zpool-import-crash.584MB.tar.bz2
Archive is 55MB, it unpacks to almost 600MB.
I'd be happy to provide additional details, this is my
first serious issue with ZFS.
And yes, I know I should've backups.
