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.
