I tried to rename and import rpool and to use those /etc/system settings,
but without success. :-(
I've tried also to do this use installed OpenSolaris 5.11 snv_111b and I
have the same result as with Solaris 10.
vladi...@opensolaris:~# zpool import
pool: rpool
id: 8451126758019843293
state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
rpool DEGRADED
mirror DEGRADED
c8d0s0 UNAVAIL cannot open
c10d0s0 ONLINE
Command "zpool import -f 8451126758019843293 rpool2" didn't change the name
of the pool in rpool2, but it updated labels with hostid before server
kernel panic came:
old labels have:
hostid=459264558
hostname=''
new label have:
hostid=12870168
hostname='opensolaris'
I didn't notice other changes in labels.
I'm lost now but I still have a hope that I will be able to recover and
import this rpool.
Is there any other possibility to test and to check zfs consistency for this
pool using some tools as zdb. The problem is hat system is panic and
rebooting. So I'm not sure how to check and catch those outputs because I
have several seconds, to monitor "zpool import" PID.
Please find below a messages output in the moment of hanging and the labels
list at the end.
Regards,
Vladimir
