Kuei,
Thanks for replying. 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!
Razvan

Razvan,
Perhaps you should open a ticket (so that specific configuration data could be
collected and analyzed) on this topic. 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.
Thanks,
Kuei

Hi Kuei-Yu (et al.)
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. ?
Best,

Razvan,
mmedquota -d -u fs:fset:
-d
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.
This option will assign the default quota to the user. The quota entry type
will change from "e" to "d_fset". You may need to play a little bit with your
system to get the result as you can have default quota per file system set and
default quota per fileset enabled.
An exemple to illustrate
User pfs004 in filesystem fs9 and fileset fset7 has explicit quota set:
# mmrepquota -u -v fs9 | grep pfs004
pfs004 fset7 USR 1088 102400 1048576 0 none | 13 10000 33333 0 none e <===
explicit
# mmlsquota -d fs9:fset7
Default Block Limits(KB) | Default File Limits
Filesystem Fileset type quota limit | quota limit entryType
fs9 fset7 USR 102400 1048576 | 10000 0 default on <=== default quota limits for
fs9:fset7, the default
fs9 fset7 GRP 0 0 | 0 0 i
# mmlsquota -u pfs004 fs9:fset7
Block Limits | File Limits
Filesystem Fileset type KB quota limit in_doubt grace | files quota limit
in_doubt grace Remarks
fs9 fset7 USR 1088 102400 1048576 0 none | 13 10000 33333 0 none <=== explicit
# mmedquota -d -u pfs004 fs9:fset7 <=== run mmedquota -d -u to get default
limits
# mmlsquota -u pfs004 fs9:fset7
Block Limits | File Limits
Filesystem Fileset type KB quota limit in_doubt grace | files quota limit
in_doubt grace Remarks
fs9 fset7 USR 1088 102400 1048576 0 none | 13 10000 0 0 none <=== takes the
default value
# mmrepquota -u -v fs9:fset7 | grep pfs004
pfs004 fset7 USR 1088 102400 1048576 0 none | 13 10000 0 0 none d_fset <=== now
user pfs004 in fset7 takes the default limits

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@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,
