I should mention that all of my other tapes are working flawlessly with
my current setup... I just have this one tape that gives MTEOM errors...
There was nothing in the system log, but I think I know what caused the
problem... I accidentally rebooted my bacula server while bacula was
writing to tape... The reboot operation just hung, and I hard-powered
the bacula server off since I figured I was screwed anyway... The tape
clearly didn't like this... I think the tape is slightly damaged... I
can restore from it, but cannot append to it... How can I move the data
from this tape onto another? Probably migration, huh?
