tape_34xx.1e4d72 <bus ID of the tape device>: Opening the tape failed because of missing end-of-file marks
Explanation
The tape block device driver requires end-of-file marks at the end of
the recorded area on a tape. If the tape device was to be opened in
response to a mount command, the mount command will fail.
User response
Insert a tape cartridge that has been prepared for use with the tape
block device driver and try the operation again.
