	I think there may be a bug when you boot the machine from a drive that is a 
member of a zfs-mirror and you have raidz pools elsewhere. 

	On reboot, I would get message saying there was no bootable kernel and 
dropped me down to the "OK" prompt. At that point, lsdev would show all the 
pools (both zfs-mirror and zraid's) and "ls" would return an error saying 
there were to many open files. 

	I was able to work around the problem by pulling all the drives in the zraid 
pool into single user, attach all the drives and use atacontrol attach to 
bring them online before going to multi-user and hitting /etc/rc.d/zfs start. 

	The only thing I haven't tried, and may be the key to the problem is 
reloading the boot-strap on the bootable drives. Would that make any 
difference?
