slurmusersettings MaxWall false alarm

[ExplorerRay]

I set users:MaxWall:30:00 in user_settings.conf and it is already set 00:30:00 in my users' association. However, it still says that User xxx currently has MaxWall=00:30:00 but configuration MaxWall=30 is different.

According to the official document, I think they are the same.

Thanks for reporting this! There is a conflict between the syntax of the user_settings.conf file where fields are separated by ":" and a parameter which actually contains ":" as part of the value, such as MaxWall=00:30:00.
The awk command in the slurmusersettings script actually splits fields on ":" field separators:
Syntax of this file is 3, 4 or 5 items separated by ":"
[DEFAULT|NEWUSER|UNIX_group|username]:[Type]:value[:partition[:cluster]]

It would therefore seem difficult for the slurmusersettings script to accommodate a "value" field with ":" in it. I apologize for this shortcoming.
You can alternatively limit the walltime per partition in slurm.conf like this:
PartitionName=pppp Nodes=nnnn MaxTime=00:30:00

I hope this helps.

Thanks for your response, but I want to set MaxWall for a specific group of users instead of whole partition.
How about switching to another delimiter in config? Because user_settings.conf with new delimiters can be generated by slurmusersettings2conf, I don't think it will affect significantly to old users.
