The resilver finished last night, so rebooted the box as I had just
upgraded to the latest Dev build. Not only did the upgrade fail (love
that instant rollback!), but now the zpool won't come online:
r...@shebop:~# zpool import
pool: datapool
id: 3410059226836265661
state: UNAVAIL
status: The pool is formatted using an older on-disk version.
action: The pool cannot be imported due to damaged devices or data.
config:
datapool UNAVAIL insufficient replicas
raidz1 UNAVAIL corrupted data
c7d0 ONLINE
c8d0s0 ONLINE
c9d0s0 ONLINE
c11d0s0 ONLINE
c10d0s0 ONLINE
I've tried renaming /etc/zfs/zpool.cache and rebooting, but no joy.
Is it OK to scream and tear my hair out now?
A little more research came up with this:
r...@shebop:~# zdb -l /dev/dsk/c7d0
--------------------------------------------
LABEL 0
--------------------------------------------
failed to unpack label 0
--------------------------------------------
LABEL 1
--------------------------------------------
failed to unpack label 1
--------------------------------------------
LABEL 2
--------------------------------------------
failed to unpack label 2
--------------------------------------------
LABEL 3
--------------------------------------------
failed to unpack label 3
While 'zdb -l /dev/dsk/c7d0s0' shows normal labels. So the new question
is: how do I tell ZFS to use c7d0s0 instead of c7d0? I can't do a 'zpool
replace' because the zpool isn't online.
ZFS actually uses c7d0s0 and not c7d0 - it shortens output to c7d0 in case it
controls entire disk. As before upgrade it looked like this:
NAME STATE READ WRITE CKSUM
datapool ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c2d0s0 ONLINE 0 0 0
c3d0s0 ONLINE 0 0 0
c4d0s0 ONLINE 0 0 0
c6d0s0 ONLINE 0 0 0
c5d0s0 ONLINE 0 0 0
I guess something happened to the labeling of disk c7d0 (used to be c2d0)
before, during or after upgrade.
It would be nice to show what zdb -l shows for this disk and some other disk
too. output of 'prtvtoc /dev/rdsk/cXdYs0' can be helpful too.
