Hello. I'm having difficulties with my Amanda setup. I have tried to
configure a RAIT device which is comprised of a 4 slot vtape chg-disk device,
and a 1 slot chg-single tape drive. What is happening is that when I have just
the chg-disk vtape changer activated, it works fine, and cycles through the
slots in the vtape directory. But when I transition to the chg-rait device, it
stops moving through the slots in the vtape directory. Looking at the files in
/var/log/amanda/server/NMHPVPR/amcheck-device.XXX.debug, when I change the
configuration, it appears that Amanda::Taper::Scan::traditional doesn't get
called as many times in the chg-rait mode as in the plain chg-disk mode.
There's also a line in the debug file about "Device is in variable block size"
