Here's what I did:
* had a t1000 with a zpool under /dev/dsk/c0t0d0s7 on solaris 10u4
* re-installed with solaris 10u6 (disk layout unchanged)
* imported zpool with zpool import -f (I'm forever forgetting to export them
first) - this was ok
* re-installed with solaris 10u6 and more up-to-date patches (again forgetting
to export it)
When I do zpool import i get the following:
# zpool import
pool: zpool
id: 17419375665629462002
state: FAULTED
status: The pool metadata is corrupted.
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.
see: http://www.sun.com/msg/ZFS-8000-72
config:
zpool FAULTED corrupted data
c0t0d0s7 ONLINE
So I thought I'd done something wrong, however checked the partition layout and
it's not changed. However after doing a bit of poking about, I've found some
weird stuff - what zdb -l is showing and what's actually on the disk doesn't
seem to tally - I can't find that transaction ID from zdb and there seems to be
a mixture of version 4 and version 10 uberblocks on disk (and they all have
bigger transaction IDs than zdb is showing).
Am I missing something?
