There are many ways to do this, our way is we set their QOS's to one 
called "batchdisable" and that QOS has "MaxJobsPerUser=0" set on it.


One of the benefits of that is it's easy to see everyone who's been 
blocked from submitting jobs.


All the best,
Chris

Does your filesystem have disk quotas?  Using disk quotas would seem to be 
a good choice to contain this problem.

This GrpCPUs group limit may perhaps affect the entire group?  Anyway, 
GrpCPUs is undocumented in the sacctmgr manual page, for which I opened a 
bug in https://bugs.schedmd.com/show_bug.cgi?id=16832


I think Sean's suggestion of maxjobs=0 is a better choice, or perhaps set 
GrpTRES=cpu=0 ?

I would but unfortunately they were creating 100s of TBs of data and I need 
them to log in and delete it but I don't want them creating more in the 
meantime.

Sean,

I was just about to mention this wasn't working because I had thought of 
something similar. I tried 'sacctmgr modify user where name= set 
maxjobs=0' but that was still allowing the user to 'srun --pty bash'. 
Apparently doing it through modifying the account as you stated does work 
though which is odd. Just have to modify each account the user has access too.

Thanks.

Regards,

Hello,

I have a badly behaving user that I need to speak with and want to temporarily 
disable their ability to submit jobs. I know I can change their account 
settings to stop them. Is there another way to set a block on a specific 
username that I can lift later without removing the user/account associations?
