Subject: [Bacula-users] Bacula unable to use autochanger during testing with
btape's fill command

Hello,

I've installed Bacula 1.38.11 on one of my servers. I'm running Red Hat 
Enterprise 3, using an Overland Power Loader with a single LT02 drive. 
Following the suggested test instructions here -

http://www.bacula.org/dev-manual/Testing_Your_Tape_Drive.html#_ChapterStart2
7

I am using btape's fill command with two volumes. The first volume fills 
fine. However, when it is full, the autochanger fails to change volumes. 
I get the following -

02-Oct 12:37 btape: End of Volume "TestVolume1" at 308:7287 on device 
"Drive-1" (/dev/nst0). Write of 64512 bytes got -1.
02-Oct 12:37 btape: Re-read of last block succeeded.
btape: btape.c:2301 Last block at: 308:7286 this_dev_block_num=7287
btape: btape.c:2335 End of tape 308:0. VolumeCapacity=212,037,168,200. 
Write rate = 26016.8 KB/s
02-Oct 12:37 btape: End of medium on Volume "TestVolume1" 
Bytes=212,037,168,200 Blocks=3,286,787 at 02-Oct-2006 12:37.
02-Oct 12:38 btape: Invalid slot=0 defined, cannot autoload Volume.
Mount blank Volume on device "Drive-1" (/dev/nst0) and press return when 
ready:

I have the mtx-changer script, which works when I run it from the 
command line. I have the autochanger configured within Bacula's 
bacula-sd.conf -

Device {
  Name = Drive-1                      #
  Drive Index = 0
  Media Type = LTO-2
  Archive Device = /dev/nst0
  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes;
  RemovableMedia = yes;
  RandomAccess = no;
  AutoChanger = yes;
  # Enable the Alert command only if you have the mtx package loaded
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}

Autochanger {
  Name = Changer-1
  Device = Drive-1
  Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
  Changer Device = /dev/sg0
}

Further, here is a snap shot of the tape drive's status before running 
btape's fill -

  Storage Changer /dev/sg0:1 Drives, 16 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 15 Loaded):VolumeTag = 
NAV520L2                       
      Storage Element 1:Full :VolumeTag=NAV522L2                       
      Storage Element 2:Empty
      Storage Element 3:Empty
      Storage Element 4:Empty
      Storage Element 5:Full :VolumeTag=CLN421L1                       
      Storage Element 6:Full :VolumeTag=NAV521L2                       
      Storage Element 7:Full :VolumeTag=NAV523L2                       
      Storage Element 8:Empty
      Storage Element 9:Empty
      Storage Element 10:Empty
      Storage Element 11:Empty
      Storage Element 12:Empty
      Storage Element 13:Empty
      Storage Element 14:Empty
      Storage Element 15:Empty
      Storage Element 16:Empty

I would greatly appreciate any insight as to why Bacula is unable to use 
the autochanger
