I'm not aware of any way to do that, and I would advise against mucking
around in the Slurm MySQL database directly.

The idea of slurmdbd is to have a comprehensive view of all jobs (within
its expiry parameters), and removing them will likely break its
statistics and probably do Bad Things(tm).

Here be dragons..

Hello,

I already increased the parameters in slurm.conf file.
So there are enough already completed jobs visible.

But users want to decide, which jobs are visible and which ones not.
For example, one failed jobs, the users knows the fail-reason and decides there 
is no reason to see this job longer in any queue (no matter which command: 
squeue or sacct).
The next job, the user does not know, why the job is failed, so he wants the 
job to stay visible for debugging.

That’s the reason for my question.

Not sure I totally grasp the rationale. Could you please explain what the 
motivation is? Do you see cases where the number of jobs in the system is close 
to the configured maxjobcount? Do you have any free memory such that you could 
increase maxjobcount? Or could you decrease minjobage and direct users to query 
sacct?

Hello,

is it possible to manually delete Jobs from slurmctld runtime database ?
I know the automatic way with MinJobAge and MaxJobcount Parameters in 
slurm.conf.
But sometimes, users want to keep some Jobs longer in the queue (also  already 
completed jobs) und other jobs could be erased from the queue very soon.

In other words: is there a possibility for users to erase jobs before MinJobAge 
is reached?
I searched very long, but didn’t find a answer.

Thank you!

Brigitte
