It is not the problem if you are running Linux. But it does look like
the output of the mtx-changer script is not correct for the 'list'
command. The excerpt from your mtx-changer script looks quite different
from the one installed on my Linux system by Bacula 5.0.2. What version
of Bacula are you using? What is the actual output of:
billie:~# /usr/lib64/bacula/mtx-changer /dev/sg2 list
/usr/lib64/bacula/mtx-changer /dev/sg2 list
-bash: /usr/lib64/bacula/mtx-changer: No such file or directory
My mtx-changer script appears to be in /etc/bacula/scripts/
billie:~# /etc/bacula/scripts/mtx-changer /dev/sg2 list
1:A0000006
2:B0000005
3:A0000005
4:A0000004
5:B0000004
6:C0000005
7:A0000007
8:C0000006
9:A0000010
10:CLNA0001
I am using debian lenny
*version
billie-dir Version: 2.4.4 (28 December 2008) x86_64-pc-linux-gnu debian
lenny/sid
thanks,
