Ah! That might explain why the amdump run ended with an error last
night. amreport said:

I've corrected this by using the same state file in both
child-changer. I'm now experiencing other problems, maybe due to some
mis-config from my part:
~# su amanda -c "/opt/amanda-3.1.0beta2/sbin/amtape rait taper"
slot ?: from av48-half-1: slot 14 not in use-slots (1-12)
slot {1,13}: volume 'RAIT-001.L4' is still active and cannot be overwritten
slot {2,14}: volume 'RAIT-002.L4'
Will write to volume RAIT-002.L4 in slot {2,14}.
What's the 'slot ?:' thingie?
~# su amanda -c "/opt/amanda-3.1.0beta2/sbin/amadmin rait tape"
The next Amanda run should go onto 6 new tapes.
The next 6 new tapes already labelled are: RAIT-002.L4, RAIT-003.L4,
RAIT-004.L4, RAIT-005.L4, RAIT-006.L4, RAIT-007.L4
~# su amanda -c "/opt/amanda-3.1.0beta2/sbin/amtape rait label RAIT-002.L4"
slot {2,14}: RAIT-002.L4
slot {2,14}: time X label RAIT-002.L4
label RAIT-002.L4 is now loaded from slot {2,14}
The amtape debug contains a lot of warnings:
Wed May 5 14:12:00 2010: amtape: pid 13697 ruid 110 euid 110 version

harmless?
