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 at 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

Really appreciate your assistance.

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.

Sent by: gpfsug-discuss-bounces at spectrumscale.org
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,
Razvan Popescu
