I have recently just upgraded amanda an amanda installation from 2.4.4p1 and
upgraded the backup host from RedHat 7.3 to Fedora FC4.
I've also conglomerated the backed up hosts from several configurations
which ran independantly of each other, into a single configuration which
amanda will manage itself (hopefully well).
Other than the move of all hosts from their respective configurations into
one, not much else has changed.
There is a host however in this new config whose backups magically disappear
after the first chunk. This host is a temporary copy of the old backup
host, something which will sit in the backup rotation for a month or two to
ensure we don't need any files off of the machine before it's completely
wiped out.
Strangely enough, level 0 backups don't want to be dumped to the holding
disks either. This is the mailout from amanda after the backup attempt
(I've removed all other hosts in order to debug this). The holding disks
are 150GB and 50GB in size respectively, both more than enough to hold any
one part of the split up disks.

*** A TAPE ERROR OCCURRED: [cannot overwrite active tape Full00].
Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
The next tape Amanda expects to use is: a new tape.

Oh yeah, the identical definitions which work on gimp, don't work on
