Re: [Bacula-users] bacula watchdog killing tape-loading

Hi John,

thanks for your help. I am quite new to bacula and it seems to take some time to fully understand it :-)
I am not sure whether it really is a timeout problem.
I increased all timeout values to 10 minutes and the killing still occurs (after 2:20min):

07-Aug 12:20 company_bacula-dir JobId 217: Start Backup JobId 217, Job=Fileserver_Lexware_Exchange_to_Tape.2008-08-07_12.20.03 07-Aug 12:20 company_bacula-dir JobId 217: Using Device "DLT-Drive-1" 07-Aug 12:20 company_bacula-sd JobId 217: 3301 Issuing autochanger "loaded? drive 0" command. 07-Aug 12:20 company_bacula-sd JobId 217: 3302 Autochanger "loaded? drive 0", result: nothing loaded. 07-Aug 12:20 company_bacula-sd JobId 217: 3304 Issuing autochanger "load slot 8, drive 0" command. *messages 07-Aug 12:22 company_bacula-sd JobId 217: Fatal error: 3992 Bad autochanger "load slot 8, drive 0": ERR=Child died from signal 15: Termination. Results=Loading media from Storage Element 8 into drive 0...done Program killed by Bacula watchdog (timeout) 07-Aug 12:20 company-appsrv-fd JobId 217: Fatal error: ../../filed/job.c:1817 Bad response to Append Data command. Wanted 3000 OK data, got 3903 Error append data

I doublechecked the time needed by the autochanger for an unload/load operation: I did a couple of operations and they all terminated in less than four minutes.
I think there is a general problem with the autochanger because btape test throws the following error when testing the autochanger:

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.
When I run this command "/usr/lib/bacula/mtx-changer /dev/sg3 loaded 1 /dev/nst0 0" manually, both as root and as user bacula, it returns "1":

[root@company-Backupserver ~]# su - bacula -bash-3.2$ /usr/lib/bacula/mtx-changer /dev/sg3 loaded 1 /dev/nst0 0 1 -bash-3.2$

Could it be a permission problem? What Uid Gid should mtx-changer have? Could some automatic mechanism on my CentOS installation have changed the permissions of the autochanger device to a lower level?

I am a little stuck here.

Thanks for all help!

Nils

The default maximum changer wait is 5 minutes. If the changer does not
complete in 5 minutes bacula will kill the mtx-changer script.
