Hello.
I have two QUANTUM media changer and currently, I have been unable to use them
with bacula concurrently. I have googled and attempted multiple changes on
configuration, no luck. I have also attempted to separate the hardware as much
as possible to avoid inter-dependency, its not working.
Here is the setup:
Bacula director runs on server1
Storage 1 on server2 (HBA card and one of the quantum tape device attached to
server2)
Storage 2 on server3 (HBA card and the second quantum tape device attached to
server3)
All windows systems are running bacula file server and submitting the backup to
server3
All Linux systems are also running bacula file server and submitting backup to
server2
Essentially, minimal dependency between the two storage systems.
I have on director:
Maximum Concurrent Jobs = 5
I have set on clients:
Maximum Concurrent Jobs = 5
On bacula-dir.conf, under storage, for each of above:
Storage {
Name = QUANTUM(1/1)
Address = 192.168.20.x
SDPort = 9103
Password = "vvvvv"
Maximum Concurrent Jobs = 3
Device = ULTRIUM-HH(1/2)
Media Type = LTO-6
Autochanger = yes
}
I have set on one storage, server3 (Linux):
Maximum Concurrent Jobs = 3
On the second storage (Windows):
Maximum Concurrent Jobs = 2
The intent of this setup is to make sure that both storage can be processing
backup concurrently. I have looked at pools too, as it seem to be common
search suggestion and there is no configuration that control job concurrency
This is what I observe:
5 jobs are running concurrently, but most of the time, all on one storage
system. The other stay idle unless there is less that 5 jobs queued that are
from Linux, at which point, Windows jobs seem to start getting processed.
Needless to say, sometimes, I don't run any Windows job
What am I missing here? How can I for example set 3 jobs maximum on each of
the two storage for a maximum of 5 concurrent jobs?
