Issues with Tape Changer in Bacula on FreeBSD

  I have an old Dell PowerVault 124T I use for home backups. It's a bit noisy, so I have it attached to an old APC master switch so I can turn it on when I want to do a backup. The catch is that the FreeBSD server I'm using might have been rebooted while the LTO array was off. So, I use camcontrol:


sudo camcontrol devlist

turns up nothing...

sudo camcontrol rescan all

now, we have an LTO drive and a changer:

            at scbus1 target 9 lun 0 (pass0,sa0)
               at scbus1 target 9 lun 1 (pass1,ch0)

So far, so good. A restart of bacula-sd should pick up the device, if needed. 

sudo service bacula-sd restart

However, I discovered that bacula couldn't see the slots in the changer when I did an update barcode slots

So, I checked the status of the storage daemon:

3301 Issuing autochanger "loaded? drive 0" command.
3991 Bad autochanger "loaded? drive 0" command: ERR=Child exited with code 127.
Results=mtx: not found

mtx not found! It was installed from ports, so I did a simple fix of 

ln -s /usr/local/bin/mtx /usr/bin

and now the command worked:

*update barcode slots
