[gpfsug-discuss] How to clear explicitly set quotas

Its a little difficult that the different quota commands for Spectrum Scale are all different in there syntax and can only be used by the "right" people.

As far as I can see mmedquota is the only quota command that uses this "full colon" syntax and it would be better if its syntax matched that for mmsetquota and mmlsquota. or that the reset to default quota was added to mmsetquota and mmedquota was left for editing quotas visually in an editor.

Regards

Peter Childs

Quick update. Thanks to a colleague of mine, John Valdes, there is a way to specify the file system + fileset + user with this form:

mmedquota -d -u <filesystem>:<fileset>:<user>

It’s just not documented in the man page or shown in the examples. Docs need to be updated!

Unfortunately it doesn’t look like there is a way to target a specific quota. So for cluster with many file systems and/or many filesets in each file system, clearing the quota entries affect all quotas in all file systems and all filesets. This means that you have to clear them all and then reapply the explicit quotas that you need to keep.

# mmedquota -h
Usage: mmedquota -d {-u User ... | -g Group ... | -j Device:Fileset ... }

Maybe RFE time, or am I missing some other existing solution?

Note that " Try disabling and re-enabling default quotas with the -d option for that fileset " didn't fix this issue.

check out the -d option for the mmedquota command:

"Reestablish default quota limits for a specific user, group, or fileset that had an explicit quota limit set by a previous invocation of the mmedquota command.”
