Thank you very much, Kuei. It’s now clear where we stand, even though I would have liked to have that added selectivity in mmedquota.
We use filesets to separate classes of projects and classes of storage (backup/noBackup for example), and thus one user or one group(=project), has various resource allocations across filesets (enforced by quotas). Sometimes we need to roll back only certain allocations and leave other untouched …. If no one else encountered this need so far, I guess we twisted the model a bit too much 😊. Maybe we can add this option to some list of desired new features for coming versions?...

I did open a ticket before the holidays, but it didn’t yield a solution. I just opened another one… My very specific question to you is: “Where have you seen this particular syntax work?” The 5.0.3 & 5.0.4 mmedquota man pages do not mention the availability of a filesystem:fileset parameter (as in your example: “fs9:fset7”) and my testing rejected such a parameter. What made you think this would work? ? # mmedquota -d -u pfs004 fs9:fset7 ^^^^^^^^^^^^^ Many thanks!

We would look at your system configuration, the code level to figure out whether what you are seeing is a problem or it is just an expected behavior or a limitation; there are some limitations, specifically moving default limits between file system and fileset default scope, that may not work for your scenario.

Happy New Year! I’d like to reiterate my follow-up question to your comments – in particular to the line copied below, which mentions a behavior that I’m seeking for this command, but cannot reproduce (in vers, 5.0.3@Linux), namely (with my highlights): # mmedquota -d -u pfs004 fs9:fset7 <=== run mmedquota -d -u to get default limits The reduction of scope to a named filesystem/fileset is what I’m seeking, *but* at least the 5.0.3 version seems to reject that parameter with an error, and apply the user’s default restoration to *all filesystems and filesets* Are you using a different version? Or a different implementations? I’m running SS 5.0.3 on Linux x64. I apologize for having to press this point, but this matter is of a certain importance to us and it appears that the public documentation is mum in this regard. Furthermore, the IBM support, at the first pass, was quite confused and unfocused. (I’m trying with a new case now, but my hopes are low). You seem to be an IBM insider, so …. I count on your help ?. Sorry, for the insistence. ?

My problem is different though. I have set a fileset default quota (doing all the steps you recommended) and all was Ok. During operations I have edited *individual* quotas, for example to increase certain user’s allocations. Now, I want to *revert* (change back) one of these users to the (fileset) default quota ! For example, I have used one user account to test the mmedquota command setting his limits to a certain value (just testing). I’d like now to make that user’s quota be the default fileset quota, and not just numerically, but have his quota record follow the changes in fileset default quota limits. To make it more technical …. This fellow’s quota entryType is now “e” . I want to change it back to entryType “I”. (I hope I’m not talking nonsense here) mmedquota’s “-d” option is supposed to reinstate the defaults, but it doesn’t seem to work for fileset based quotas … !?!
