[slurm-users] changing JobAcctGatherType on busy cluster?

[Alex Chekholko]

Hi,

Right now I have a cluster running SLURM v17.02.7 with:

JobAcctGatherType       = jobacct_gather/none

The documentation says "NOTE: Changing this configuration parameter changes
the contents of the messages between Slurm daemons. Any previously running
job steps are managed by a slurmstepd daemon that will persist through the
lifetime of that job step and not change it's communication protocol. Only
change this configuration parameter when there are no running job steps."

I want to change the parameter to
JobAcctGatherType       = jobacct_gather/linux

Does this mean I need a full cluster downtime to do this?

Also I guess this means that since this cluster was put into production,
not a single user or admin has wanted to run 'sstat'?

Regards,
Alex
