[pkg-bacula-devel] Bug#728582: bacula-sd on kFreeBSD: unable to use tape drive

Sun Nov 3 10:15:16 UTC 2013

Package: bacula
Version: 5.2.6+dfsg-9
Severity: important

Dear Maintainer and Developers,
bacula is unable to use tape drives on Debian kFreeBSD.
Using tape drives within bacula works with the Linux Kernel on amd64 and
sparc without any problem. Native FreeBSD with bacula works too.

bacula-sd is able to use disk storage without problems. But no tape drive.

This problem is only reproducable on kFreeBSD Systems!

The hardware works with kFreeBSD, I am able to use the tapedrive and the
changer with the mt, mtx and tar commands without problems.

But when using the bacula tools, tape access fails:

=== Write, rewind, and re-read test ===

I'm going to write 10000 records and an EOF
then write 10000 records and an EOF, then rewind,
and re-read the data to verify that it is correct.

This is an *essential* feature ...
