Nope per the documentation you have to restart the slurmctld to change
MaxJobCount.

Hi,
I want to increase the MaxJobCount in the slurm.conf file from its
default value of 10,000. I want to increase it to 250,000.
The online documentation says:
MaxJobCount
The maximum number of jobs Slurm can have in its active database at
one time. Set the values of MaxJobCount and MinJobAge to ensure the
slurmctld daemon does not exhaust its memory or other resources. Once
this limit is reached, requests to submit additional jobs will fail.
The default value is 10000 jobs. NOTE: Each task of a job array counts
as one job even though they will not occupy separate job records until
modified or initiated. Performance can suffer with more than a few
hundred thousand jobs. *_Setting per MaxSubmitJobs per user is
generally valuable to prevent a single user from filling the system
with jobs. This is accomplished using Slurm's database and configuring
enforcement of resource limits. This value may not be reset via
"scontrol reconfig". It only takes effect upon restart of the
slurmctld daemon._*

My assumption is that a restart of the slurmctld daemon is only needed
if “Setting per MaxSubmitJobs per user”, which would be done by
updating the slurm database.
To just update the value of the MaxJobCount in the slurm.conf file, I
assume I edit the slurm.conf file with the new value and run a
‘scontrol reconfigure’ to update it. That is all that is needed, right??
