It might help if you could run mdb over the kernel crashdump files so
developers would at least have a stack trace of what went bad. Maybe they would
have more specific questions on variable values etc. and would post those - but
the general debugging steps (see Wiki) come first anyway.
So far you can also try to trace your pool with zdb -bscvL or similar to check
for inconsistensies - i.e. if the box crashed/rebooted with io's written out of
order like labels or uberblocks updated before the data they point to was
committed, if the disks/caches lied.
Then you might have luck rolling back a few txg's on import, and you can model
if this helps with zdb as well (so it would start with an older txg number and
skip the possibly corrupted last few sync cycles).

Тема: [OpenIndiana-discuss] Zpool crashes system on reboot and import
All,
Some time back we had issue where I last entire zpool file system
due to possible bad raid controller card. At that time I was strongly
encouraged to get a raid card that supported JBOD and allow ZFS to
control all disks. Well I did that and unfortunately today I lost an
entire zpool that was configured with mutiple raidz2 volumes. See below:

errors: No known data errors
The system crashed and when rebooted it would just core dump and
reboot. After booting in single user mode I found the zpool that was
crashing the system. Exported that out and was able to bring the system
back up. When I try to import that pool it would again crash my system.
I finally found that I could import the pool without crashing my system
if I imported it read only:
zpool import -o readonly=on data
That is the output I have now above from the pool imported as readonly.
Looking for any advice on way to save this pool??? As you can see zpool
reports no errors with the pool.
