Hello to everyone.
We have a lustre (v1.8.4) test cluster with 2 MDSs, 2OSSs and 4 Clients.
I am experimenting with the quotas but something seems to not work.
In first I did a
cli1# lfs quotacheck /lustre
cli1# lfs quotaon -ug /lustre
cli1# lfs quota /lustre
To get ::
Disk quotas for user root (uid 0):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre/jtest1/ [0] 0 0 - [0] 0 0
-
Some errors happened when getting quota info. Some devices may be not
working or deactivated. The data in "[]" is inaccurate.
Disk quotas for group root (gid 0):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre/jtest1/ [0] 0 0 - [0] 0 0
-
Some errors happened when getting quota info. Some devices may be not
working or deactivated. The data in "[]" is inaccurate.
So I tried ::
mds2# cat /proc/fs/lustre/lquota/jtest1-MDT0000/quota_type
>> ug3
oss1# cat /proc/fs/lustre/lquota/jtest1-OST000{1,3}/quota_type
>> ug3
>> ug3
oss2# cat /proc/fs/lustre/lquota/jtest1-OST000{0,2}/quota_type
>> ug3
>> ug3
Then I tried ::
cli1# lfs quotaon -ugf /lustre
cli1# lfs quota /lustre
>>user quotas are not enabled.
>>group quotas are not enabled.
mds2# cat /proc/fs/lustre/lquota/jtest1-MDT0000/quota_type
>> 3
oss1# cat /proc/fs/lustre/lquota/jtest1-OST000{1,3}/quota_type
>> 3
>> 3
oss2# cat /proc/fs/lustre/lquota/jtest1-OST000{0,2}/quota_type
>> 3
>> 3
And then again ::
cli1# lfs quotaon -ug /lustre
cli1# lfs quota /lustre
>> Disk quotas for user root (uid 0):
Filesystem kbytes quota limit grace files quota limit
grace
>> /lustre/jtest1/ [0] 0 0 - [0] 0 0
-
>> Some errors happened when getting quota info. Some devices may be not

>> Disk quotas for group root (gid 0):

grace
>> /lustre/jtest1/ [0] 0 0 - [0] 0 0
-
>> Some errors happened when getting quota info. Some devices may be not

mds2# cat /proc/fs/lustre/lquota/jtest1-MDT0000/quota_type
>> ug3
oss1# cat /proc/fs/lustre/lquota/jtest1-OST000{1,3}/quota_type
>> ug3
>> ug3
oss2# cat /proc/fs/lustre/lquota/jtest1-OST000{0,2}/quota_type
>> ug3
>> ug3
So I would like to make a few questions in case anyone knows.
First of all is this a known issue, or am I doing something wrong here? I
am forcing the quotaon and that reacts as if I did a quotaoff.
Furthermore I would like to ask about this number 3 in the quota_type files
in case anyone knows what does it mean and why is this necessary.
Finally if I am not doing something wrong here, is there a way to fix this ?
Thank you in advance for your time and any replies/guidance/directions.
Stelios.
