I'm moving to unionfs clean systems, since I *really* want to get out of 
4.x ... in the case above, its a brand new Dual Xeon, had something like 
20 jails running on it ... 3x73G Seagate drives running RAID5 ... middle 
drive (ID1) failed, working on a replacement drive for it ... I suspecting 
the problem has to do with the failed drive ;(

The drive controller is the ICP GDT8514RZ Controller, which, oddly enough, 
I get told isn't installed when I try to use icpcon (for 4.x) to connect 
to it :(
