I've tried to figure this out on my own with searches and going through the
manual and I need some clarification. I've included the relevant section
of the bacula-sd.conf file below. I'm confused because I think this should
work properly but I am getting the message "is waiting on max Client jobs"
for all additional jobs that are running after the first. Every other
daemon's config has maxes of 20 jobs. Since I have 5 devices in my
autochanger, should I add a line in the Autochanger section for "Maximum
Concurrent Jobs = 5", or should I set them to 5 in the device sections?
I also am confused about the spool directive. The server running bacula
has 2x 1tb drives in a mirror zfs pool. I wonder how large I could make
the spool directives. It isn't clear to me when I set the spool directives
in each device section, if they all share "Maximum Spool Size = 100g" or if
each of the 5 drives will allocate 100gb then using 500gb total of my disk
space. if I want to never exceed 80% used space on the zpool and I also
need 150gb for VMs and also need space for the catalog backing up 12-15tb
of files, how high should I set the max and job spools?
Thanks,
Nate
