one more point of interest: when i first went to setup the file server i
had two drives on the scsi bus and i tried to have them both interleave
as the main drive (i followed the wiki's instructions). When I went to
do a replica it would always crash.
if you are interested I can send send the hardware to you for you to
work on, i have no shortage of machines (just scsi interfaces).
