[Bacula-users] Dell autochanger not changing

Thu, 02 Oct 2014 17:02:31 -0700 

The times they are a-changing, but my Dell Autochanger sure isn't...
I'm working at getting an initial install of bacula up and running. My backup server is a Dell R510 running CentOS 7.0, which has bacula version 5.2.13-18 in the yum repository. I'm using mysql for the data base. We're going to be writing to a Dell ML6000 (a re-labeled IBM Ultrium TD6) with LTO-6 tapes, which hold 2.5TB native. There is one tape drive and 40 tape slots in the Dell autochanger, with 30 new, unused tapes in them.
I've got the director successfully talking to the database and the local file daemon. I believe that the storage daemon is successfully talking to the autochanger and the tape drive because in bconsole, I was able to add the tapes to the Default pool: 


*add pool=Default storage=ML6000-LTO3-0
You probably don't want to be using this command since it
creates database records without labeling the Volumes.
You probably want to use the "label" command.

Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
Enter number of Volumes to create. 0=>fixed name. Max=30: 30
Enter base volume name: LTO6-Vol
Enter the starting number: 000001
Enter slot (0 for none): 1
InChanger? yes/no: yes
30 Volumes created in pool Default
You have messages.
At first, it seemed to have done what I wanted, which was to get all of the tapes into the Default pool. In bconsole, I ran "list media", which gave me: 
========================================================


*list media
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"

Now when I attempt a local backup, here's what I get:
========================================================
02-Oct 16:09 bacula-dir JobId 14: No prior Full backup Job record found.

I built my bacula-sd.conf file from what I saw at:

http://wiki.bacula.org/doku.php?id=sample_configs

From my bacula-sd.conf
=====================

Autochanger {
  Name = "ML6000 Library"
  Device = ML6000-LTO3-0
  Changer Device = /dev/sg8
  Changer Command = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"
                    # %c = changer device
                    # %o = command (unload|load|loaded|list|slots)
                    # %S = slot index (1-based)
# %a = archive device (i.e., /dev/sd* name for tape drive) 
                    # %d = drive index (0-based)
}

Device {
  Name = ML6000-LTO3-0
  Archive Device = /dev/nst0
  Device Type = Tape
  Media Type = LTO-6
  Autochanger = Yes
Alert Command = "sh -c '/usr/sbin/tapeinfo -f /dev/sg7 | /bin/sed -n /TapeAlert/p'" 
  Drive Index = 0
  RemovableMedia = yes
  Random Access = no
  Maximum Spool Size = 100gb
  Maximum Job Spool Size = 60gb
  Spool Directory = /backup/spool
  Automatic mount = Yes
}
Why is it bconsole can talk to the autochanger and get it to label all of the tapes, yadda, yadda, but I can't get a backup job to load a tape? 


Thanks!
