Hi,

I have a 3 drive autochanger (bacula 2.2.8). Right now I configure
each job to use one of the 3 drives, not the changer device.


Storage {
  Name = Neo4100
  Address = ....
  SDPort = 9103
  Password = "wiped"
  Device = Neo4100
  Media Type = LTO4
  Autochanger = yes
  Heartbeat Interval = 5min
  Maximum Concurrent Jobs = 3
}

Storage {
  Name = Neo4100-LTO4-D1
  Address = ....
  SDPort = 9103
  Password = "wiped"
  Device = ULTRIUM-TD4-D1
  Media Type = LTO4
  Maximum Concurrent Jobs = 1

[2 more drives]

And in the client's job config I then use

Storage = Neo4100-LTO4-D1 
or
Storage = Neo4100-LTO4-D2


Now I would like to go back to the more typical bacula approach, where I use
the changer device in the client's job config.

But I don't want concurrent jobs running on each drive. I want that it's
possible to run 3 jobs on the changer (one for each drive), but only one on
each drive at the same time.

I could achieve that with different Priorities, but then these jobs are
blocking jobs which are using other storage devices.

Any ideas?

Ralf
