Currently there is no function to revert an explicit quota entry (e) to
initial (i) entry.

Thanks for your kind reply.
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 … !?!

It sounds like you would like to have default perfileset quota enabled.
Have you tried to enable the default quota on the filesets and then set the
default quota limits for those filesets?
For example, in a filesystem fs9 and fileset fset9. File system fs9 has
default quota on and --perfileset-quota enabled.
# mmlsfs fs9 -Q --perfileset-quota
flag value description
------------------- ------------------------
-----------------------------------
-Q user;group;fileset Quotas accounting enabled
user;fileset Quotas enforced
user;group;fileset Default quotas enabled
--perfileset-quota Yes Per-fileset quota enforcement
#
Enable default user quota for fileset fset9, if not enabled yet,
e.g. "mmdefquotaon -u fs9:fset9"
Then set the default quota for this fileset using mmdefedquota"
# mmdefedquota -u fs9:fset9
..
*** Edit quota limits for USR DEFAULT entry for fileset fset9
NOTE: block limits will be rounded up to the next multiple of the
block size.
block units may be: K, M, G, T or P, inode units may be: K, M
or G.
fs9: blocks in use: 0K, limits (soft = 102400K, hard = 1048576K)
inodes in use: 0, limits (soft = 10000, hard = 22222)
...
Hope that this helps.

Hi,
I’d like to revert a user’s quota to the fileset’s default, but “mmedquota
-d -u <username>” fails because I do have not set a filesystem default….
[root at xxx]# mmedquota -d -u user
gsb USR default quota is off
(SpectrumScale 5.0.3 Standard Ed. on RHEL7 x86)
Is this a limitation of the current mmedquota implementation, or of
something more profound?...
I have several filesets within this filesystem, each with various quota
structures. A filesystem-wide default quota didn’t seem useful so I never
defined one; however I do have multiple fileset-level default quotas, and
this is the level at which I’d like to be able to handle this matter… Have
I hit a limitation of the implementation? Any workaround, if that’s the
case?
Many thanks,
