If you have enough disk space you could try rescuing the data using dd
or cat and creating a replacement volume like this (tape in /dev/st0):

<stop bacula processes>

cat /dev/st0 > /big_file_system/tapedata.dat

mtx unload

<remove old tape>

<insert new tape>

mtx load <slot number>
mt -f /dev/st0 rewind
mt -f /dev/st0 weof # probably unnecessary for a new tape

cat /big_file_system/tapedata.dat >/dev/st0

I have no idea if this would work, but a verbatim copy of the data
on a new tape should be accepted by bacula just fine.

All the best, Uwe
