The Linux SCSI tape device driver has default settings which cause  a
lot  of  problems  whenever  you  try to run multivolume backups. For
details please see "man 4 st".

Most critical options are:  MT_ST_BUFFER_WRITES,  MT_ST_ASYNC_WRITES,
MT_ST_READ_AHEAD.  Especially  the combination of MT_ST_BUFFER_WRITES
and MT_ST_ASYNC_WRITES prevents any way to  reliably  handle  end  of
tape conditions.

Try if it helps to turn off all these options by issuing the command:
"mt -f /dev/nst0 rewind ; mt -f /dev/nst0 stoptions 0" after mounting
a tape; if this is an autoloader device, add these commands  to  your
mtx-changer script after loading a tape.

Best regards,

Wolfgang Denk
