[Bacula-users] Bacula has write errors after replacing Autoloader
|

I'm having a problem with Bacula and my Autoloader/tape drive.
OS = Fedora 10
Bacula version = 2.4.2
Tape Drive = Quantum Superloader 3 - LTO3
Here is the problem up until a week ago everything was working fine. When I
was trying to label a new tape for Bacula to use the tape broke off into the
drive.
I called Quantum tech support and they sent me a replacement unit. The only
thing that has changed was the autoloader and drive. Now I am getting write
errors on all of my backup tapes old or new. The drive also requires
cleaning after every write error .Here is an example of the output.

I called Quantum support to test and see if maybe they sent me a faulty
autoloader. They had me install their diagnostic software called xTalk. I
loaded a new tape and they had me run a few tests. I ran the health check
and a Full Read/Write test. They both passed. Their were no errors in the
xTalk log that pointed to hardware problems. So they would not replace the
unit. I tried backing up to that same tape that night and it also gave the
same write error message. So I ran btape for some more testing. The test job
ran fine with no errors. I ran the fill command and it failed. Here is the
output.
