Josip:

That is obviously the problem, but I'm not sure why it has occurred, or how to correct it. These are standard LTO2 tapes, that were previously used in a different setting. I used an mt command, mt -f /dev/nst0 weof to write an end of file mark at the begining so I could use bacula to re-label them. All of the tapes are marked with a maxvolbytes of 53,687,091,200. volbytes is set to 64512 in each of them. I guess something was changed significantly between the 5.X version of bacula and 9.6, but it also might be the upgrade of Slackware. I also don't recall the shoeshine parameter being enabled in the prior release. In my current setup, which I  will probably have to re-create, my spool files grow quite large.

Thank you for pointing my search to a satisfactory solution.

Stracchino for his help in getting things configured properly.) I am
backing up to LTO2 tapes which should have a minimum of about 200 gigs
of storage. I seem to be getting requests to mount a new tape after
about 80 gigs. Initially I thought that perhaps a tape had some sort
of defect, but that was disproved when I put in a previously unused
tape. Perhaps I have not configured some parameter properly. Can
someone suggest what parameter I might be able to change or add to
assure more complete tape utilization? (I should mention that the tape
drive wrote complete tapes under the old release.)


Hi Alan

I would suggest to use the bconsole command llist to check the
current media parameters.

Specifically, check for variables like maxvolbytes, maxvolfiles and
maxvoljobs.


Regards!
