It seems you're using the IBM lin_tape driver on this host.

You should switch back to the standard Linux kernel st one and will find
things working.


Yes, I have deployed the IBM lin_tape driver.


If you want to use lin_tape due to its features, ...

To be honest, as we purchased an IBM autochanger, the thinking was that
we would need to deploy the IBM lin_tape driver.

The suggestion, that we might not have needed it, is very interesting.

Hello Kevin,

I can save you a lot of time and tell you affirmatively that the lin_tape 
driver simply is not supported with Bacula.

I have done quite a bit of testing (for certifications of Bacula Enterprise) in Quantum's lab with and without the lin_tape driver on LTO8, 9, and 10 drives.

What works:
- Writing backup data to a tape
- Reaching the EOT, recognizing EOT and re-reading last block written
- Loading a tape moving to a specific filemarker and reading data for a restore.

What does not work:
- Loading an appendable tape and moving to EOD

This issue has not been resolved, and from what I understand from our developers, it does not appear to be in the plans for Bacula Enterprise.

Maybe someone in the Community can propose a solution?  :)


Hope this helps,
Bill
