Hello,

Some place in the manual, there is a checklist of what to do before putting something into production.  Though it doesn't explicitly say this, it should also be used if you change some significant component such as the Autochanger.  One of the tests is to run btape and specifically the "test" and "autochanger" commands.  Doing that would very likely have identified the problem.

Unfortunately this advice is too late to help you, but hopefully it can help someone in the future.

Best regards,
Kern

Hi Ana,

 

in my case (a very, very dumb fault), the path in "changer command" was wrong. No error messages

hab been displayed, just the "Autochanger has 0 slots".....

Hello Ana,

 

What I recently experienced was "Autochanger has 0 slots" error when "AutoChanger = yes" line is missing in Device directive in bacula-sd.conf with Centos 6 and Bacula 5.2.13

 

Best regards,

 

Suleyman

Hello Rainer,

 

Can you try changing Device Name? You have Name and Media Type using the same "LTO-5". Bacula doesn´t work fine when you use the same name for different things. If you could, I recommend you setting name with "Drive-0" or something like this:

 

Autochanger {

  Name = Autochanger

  Device = Drive-0

 

Device {

  Name = Drive-0

  Drive Index = 0

  Media Type = LTO-5

...

}

 

Best regards,

Ana

Hi Süleyman,

this is the current definition:

 

Autochanger {

  Name = Autochanger

  Device = LTO-5

  Changer Command = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"

  Changer Device = /dev/changer

}

 

Device {

  Name = LTO-5

  Drive Index = 0

  Media Type = LTO-5

  Archive Device = /dev/nst0

  AutomaticMount = yes;

  AlwaysOpen = yes;

  RemovableMedia = yes;

  RandomAccess = no;

  AutoChanger = yes

  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"

  Spool Directory = /data/bacula-spool

  Maximum File Size = 12GB

  Maximum Spool Size = 3200G

#  Maximum Block Size = 2000000

}

 

Do you have an other idea?

Rainer

Merhaba Can,

 

Maybe the Device directive in bacula-sd.conf, where the drives are defined, is missing AutoChanger = yes line.

 

Regards,

Hi,

Check this posts:

http://www.freebsddiary.org/tape-library.php
http://www.freebsddiary.org/tape-library-integration.php

Same issue were discussed before. (http://sourceforge.net/p/bacula/mailman/bacula-users/thread/20130306100525.GD22024 AT nionex DOT net/)

Quoting Rainer Hackel <rainer.hackel AT degnerpartner DOT com>:

Hello Bacula users,

Have some problems with a Quantum SuperLoader 3 LTO-6, and try to break them down in small pieces… here is one:

 

“update slots“ command in bconsole says:

Automatically selected Catalog: MyCatalog

Using Catalog "MyCatalog"

Automatically selected Storage: Autochanger

Connecting to Storage daemon Autochanger at 192.168.1.15:9103 ...

3306 Issuing autochanger "slots" command.

Device "Autochanger" has 0 slots.

No slots in changer to scan.

 

But:

“/usr/libexec/bacula/mtx-changer /dev/changer slots” reports 16

 

Of course the Autochanger has 16 slots.

Someone has  an idea?

 

Best regards

Rainer
