[Bacula-users] Maximum Concurrent Jobs in job definition

Hi everyone,
I have a job that runs very frequently, and successive runs take different sets of data (as determined by a pre-job script). To avoid problems, my pre-job script sets a lock file and the post-clears it.

When I configure my director for concurrent jobs = 2, i sometimes get 2 of these jobs trying to run in parallel (which is understandable, many times a run has more data than the average and is still running while the next one is due). My pre-script will then cancel the execution of the 2nd script (because it finds the lock file). Great.

Of course, this is generating a bunch of (expected) errored jobs . I read in the documentaiton [1] that I can use "Maximum Concurrent Jobs" in the Job def, to determine how many of this jobs can start in parallel. So I set this to 1 [2]

But it has no effect . I get 2 jobs running in parallel (for a short while, until the pre-script kills it). If I change the director's Max Concurrent Jobs to 1, then it's forced to 1 (but i need more than one, as I as have spooling enabled and other jobs writing to the tape too..)

What is going on ?

TIA!
B
