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#_ChapterStart27

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
