Late last week I had my first run at Bacula on a Linux server with
self-contained storage and an LT04 16 slot tape library (a Dell PV-124T)
connected by a SAS controller. I ran 2.4.4-1 as it was the default under Debian
stable. After a few dry runs and problems I succeeded in backing up just over
2TB of data to 3 tapes (just over 2 tapes) at around 70MB/s. Retrieves went
fine.

I've now upgraded to 5.0.2-1 using Debian backports so that we can run
close to the latest version. I'm using much the same configuration, but
both the Storage service and btape hang after trying to access the
drive.

It looks like I've still got access to the library, but somehow I've lost
connection to the actual tape drive.

As the server and tape drive are in a data centre I'd be glad for advice on
what to do next!

Regards
Rory
