Hi;
I have been working with bacula for almost 10 years. It’s a
great program and I’ve installed in several servers without issues, Also It has
saved me several times! 😉 . Recently I’ve been preparing a Bacula server with
the latest version 9.0.4 with a HP Ultrium 7 tape drive. After running
successfully the btape test run, I performed the first backup and restore to
test the unit. During the first backup its fails with the following error:

As the error implies I ran the HP LTT tools but as far as I went all drive
diagnostics seems to be ok.
Looking into the failed backup job, it’s seems that the job failed just after
files are backed up, since all test jobs have the same size, around 5GB which
is the size of the test files. Also I can restore it back but finished with the
same error. The files are not stored in the catalog since the backup job fails,
so I had to restore all files at once.

Testing a HP Ultirum 6 unit, Bacula works flawlessly.
So I’m starting to doubt about this unit despite its diagnostics seems to be
ok. Also I will upgrade the firmware and also driver from HPe site, and test.
Also perform a tar test round.
But meanwhile, I’m wondering if one of you have experienced something like
this? Are LTO-7 compatible with Bacula? Are there some special
parameters/config for this units (LTO-7) ?
Thanks in advance.
