Re: [Bacula-users] Max Wait Time setting
2015-07-09 12:19:02
These backups are disk-based, so this is not a timing issue with a
tape library.
From the documentation:
Max Wait Time = <time> The time specifies the
maximum allowed time that a job may block waiting for a resource
(such as waiting for a tape to be mounted, or waiting for the
storage or file daemons to perform their duties), counted from the
when the job starts, (not necessarily the same as when the job was
scheduled). This directive works as expected since bacula 2.3.18.
Given that, my expectation is that if there are no available volumes
when the job starts, the reported End time should be (in this case)
600 seconds after the reported Start time. As seen in the log
entries, that is not the case. The Maximum Volumes setting was more
than adequate for the job to run successfully, but instead it was
cancelled immediately upon starting when Max Wait Time was set. No
other "max time" parameters are defined.
The wait timer appears to be starting at the Scheduled time,
contrary to the documentation. If I wanted it to work that way, I
would use the Max Start Delay or Max Run Sched Time parameters
instead. I, too, suspect a bug, but notes in bug report 1586
indicate that the investigator was unable to reproduce the problem.

Hello
Brendan,
If
you're working with tape libraries, I would recomend you to
slightly increase this value. There are three device
directives (maximum open/rewind/changer wait) that defaults to
600 seconds. So maybe you're not giving enough time for your
volumes being mounted by Bacula.
About
you log, for JobId 542, it exceeded the maximum wait time at
22:15, 10 minutes after the scheduled time, 22:05. So I
suppose it is working as expected, since after the start time,
a few minutes later, bacula tries the mount operation and then
starts counting the Max Wait Time.
I
don't know why the log shows start time equal to end time for
these jobs, maybe this is a bug in this version.
Best
regards,
Ana
