[OpenIndiana-discuss] OI 151_a7 crashing when trying to import ZFS pool

[CJ Keist]

Been awhile, thank you all for the recommendations.  It took six days to 
restore all the data from backups!  The LSI MegaRaid 9260-8i doesn't 
support JBOD, so I had to restore using the one large disk volume again.
I will be shopping for a new raid controller card that supports JBOD and 
will rebuild this file server.  Any recommendations for a good JBOD 
controller that works well with OI?  Must be able to handle 85 disks.

Thanks...
