Hi Clint,
Your symptoms to point to disk label problems, dangling device links,
or overlapping partitions. All could be related to the power failure.
The OpenSolaris error message (b134, I think you mean) brings up these
bugs:
6912251, describes the dangling links problem, which you might be able
to clear up with devfsadm -C
6904358, describes this error due overlapping partitions and points to
this CR:
http://defect.opensolaris.org/bz/show_bug.cgi?id=13331
If none of the above issues match, review what ZFS thinks the disk
labels are and what the disk labels actually are post-power failure.
On the OpenSolaris side, you can use zdb command to review the disk
label information. For example, I have a pool on c5t1d0 so to review the
pool's idea of the disk labels, I use this command to review whether
the disk labels are coherent.
# zdb -l /dev/rdsk/c5t1d0s0
Review the above bug info and if it turns out that the disk labels
need to be recreated, maybe someone who had done this task can help.
Thanks,
Cindy

Hello,
Due to a power outage our file server running FreeBSD 8.0p2 will no longer come
up due to zpool corruption. I get the following output when trying to import
the ZFS pool using either a FreeBSD 8.0p2 cd or the latest OpenSolaris snv_143
cd:
FreeBSD mfsbsd 8.0-RELEASE-p2.vx.sk:/usr/obj/usr/src/sys/GENERIC amd64
mfsbsd# zpool import

status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using
the '-f' flag.

I don't really need to get the server bootable again, but I do need to get the
data off of one of the file systems. Any help would be greatly appreciated.
Thanks,
Clint
