Dear all
We ran into a nasty problem the other day. One of our mirrored zpool
hosts several ZFS filesystems. After a reboot (all FS mounted at that
time an in use) the machine paniced (console output further down). After
detaching one of the mirrors the pool fortunately imported automatically
in a faulted state without mounting the filesystems. Offling the
unplugged device and clearing the fault allowed us to disable
auto-mounting the filesystems. Going through them one by one all but one
mounted OK. The one again triggered a panic. We left mounting on that
one disabled for now to be back in production after pulling data from
the backup tapes. Scrubbing didn't show any error so any idea what's
behind the problem? Any chance to fix the FS?
We had the same problem. Victor pointed my to
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6742788
with a workaround to mount the filesystem read-only to save the data.
I still hope to figure out the chain of events that causes this. Did you
use any extended attributes on this filesystem?
