Inspect the tapelist at your /build/path/etc/amanda/DailySet1/, usually
/usr/local/etc/amanda/, something went agaga. It sounds as if there are only
2 entries, where there should be 5. Amlabel originates that file, and amdump
shuffles the list as they are used.

If the system is not 'adjusted' by human hands :), the normal tape usage will
be in the order they were labeled. I use a script that increments the tape
number as they are being labeled when I need to restart the whole thing as I
did about 60 days back due to a drive failure of the drive the vtapes I use
were on.
Any other problems should be found by an su amanda -c "amcheck DailySet1"
where 'amanda' is the user who will run the backups. That user can be anyone,
but should be a member of the group disk or backup, even bin for some
distributions. Probably compiled in & fixed by RH if its rpm's. And my
advise isn't going to be 100% spot on as I don't use the rpms.
