Re: [Bacula-users] ERR=Child died from signal 15: Termination

Hi John,

I checked it, /dev/sg3 is the right device. I may have found something odd.
I did a couple of load/unload operations with both mtx and mtx-changer and they worked well. I then tried to load an empty slot and got the following output:
[root@company-Backupserver ~]# /usr/lib/bacula/mtx-changer /dev/sg3 load 1 /dev/nst0 0 Loading media from Storage Element 1 into drive 0...Source Element Address 256 is EmptyThe interesting thing is that the command did not terminate. I waited for about 6 minutes but nothing happened. After that I canceled the command (CTRL-C).
Is this how it's supposed to be? If not then maybe it is something like this that makes bacula go crazy.

Thanks, Nils

Hi Folks,

this is what btape test just told me while testing my autochanger:

=== Autochanger test ===
3301 Issuing autochanger "loaded" command.
3991 Bad autochanger command: /usr/lib/bacula/mtx-changer /dev/sg3
loaded 1 /dev/nst0 0
3991 result="": ERR=Child died from signal 15: Termination
You must correct this error or the Autochanger will not work.

Are you 100% sure that /dev/sg3 is your changer? I ask this because on
my system my device nodes changed after a reboot. I fixed this with a
udev rule though.

You can test the node with the tapeinfo command

# tapeinfo -f /dev/autochanger1
Product Type: Medium Changer
Vendor ID: 'EXABYTE '
Product ID: 'MAGNUM 224      '
Revision: 'C112'
Attached Changer: No
SerialNumber: '000089000435'
SCSI ID: 3
SCSI LUN: 1
Ready: yes

Running "/usr/lib/bacula/mtx-changer /dev/sg3 loaded 1 /dev/nst0 0"
manually (even as user bacula) returns the correct loaded slot-number 1:

-bash-3.2$ /usr/lib/bacula/mtx-changer /dev/sg3 loaded 1 /dev/nst0 0
1

Is there a way to increase debugging so that I can find out why exactle
so command terminated when run by btape.
Maybe someone who knows the code a bit could spread some light.

btape -d 1000

John
