Many thanks – that’s exactly what I’m looking for. Unfortunately I have an
error when attempting to run command :
First the background:
[root@storinator ~]# mmrepquota -u -v --block-size auto gsb:home |grep rp2927
rp2927 home USR 8.934G 10G 20G 0
none | 86355 1048576 3145728 0 none e
[root@storinator ~]# mmlsquota -d --block-size auto gsb:home

entryType
gsb home USR 20G 30G | 1048576 3145728 default
on
gsb home GRP 0 0 | 0 0 i
And now the most interesting part:
[root@storinator ~]# mmedquota -d -u rp2927 gsb:home
gsb USR default quota is off
Attention: In file system gsb (fileset home), block soft limit (10485760) for
user rp2927 is too small. Suggest setting it higher than 26214400.
Attention: In file system gsb (fileset home), block hard limit (20971520) for
user rp2927 is too small. Suggest setting it higher than 26214400.
gsb:home is not valid user
A little bit more background, maybe of help…

Subject: Re: [gpfsug-discuss] Quota: revert user quota to FILESET default
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

# mmlsquota -u pfs004 fs9:fset7

# mmedquota -d -u pfs004 fs9:fset7 <=== run mmedquota -d -u to get

# mmrepquota -u -v fs9:fset7 | grep pfs004

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,
