Hello List,
since upgrading one of my Directors and the connected SD to 3.0.0 last
week, i've noticed that every couple of writes to tape, the volume will
get marked in error because of "Number of Files mismatch".
The same director writing to the same SD on a disk device works without
problems, so i'm suspecting a change to one of the default values of the
device resource maybe? To me it looks like the File count in the MySQL
does not get incremented after completing the write job.
I'm a little bit stumped because this configuration has been running
well for about a year now, over the weekend i used bscan on all of my
disk and tape volumes to build a new catalog, since i suspected the
upgrade script (even though very simple) might have broken something so
the increment didnt work anymore. Since i now have a new Catalog and it
is still doing the same thing, here i am asking if any of you know this
behavior.
Next i will be trying the btape testsuite again, seeing if something
changed which i didnt see in the changelog that will force me to use
some kind of twoeof or somethingorother option.

So in this example output, the tape 55LT was put back to a usable state
manually, used ok, marked in error, the next tape (new, empty and
labeled with 3.0.0) was then used ok, and the next job marked it in
error too...
I'm off to start the btape testsuite on another empty tape, but i hope
someone has an idea. I would really like accurate backups and the diff /
full intervals of the scheduler.. I've been looking forward to this
release since it was first announced some time last year, thanks for the
hard work.. 2 more features and it will be the perfect backup solution
for me (resuming on connection interruption and client initiated backups...)
Thanks for your time
