[OpenIndiana-discuss] Zpool crashes system on reboot and import

[CJ Keist]

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.
