Hi,
I'm running a Linux system with kernel version 3.18.19.
While experimenting with groups quota, I did the following steps:
1. Mounted XFS with both users and groups quota enabled
2. Set user 0 (aka the SuperUser) hard limit to 800000 . I believe
that this has the same affect as using xfs_quota limit command with
"-d" (i.e. setting the default hard limit for users which don't have
their hard limit set explicitly)
3. Set user 2001117 hard limit to 1024000 (I set a different limit
than user 0's on purpose, in order to show that the group hard limit
was not inherited from this user, but from user 0)
4. Created a 1MB file that is owned by user 2001117 and group 2000514
5. Group 2000514 which previously didn't have any hard limit defined
now "inherited" user 0 hard limit of 800000 .
See output of xfs_quota below.
Thanks,
Yaron
Before creating the file:
==================
root@vsa-0000011e-vc-0:~# xfs_quota -x -c "report -L0 -U 2100000"
/export/share_3
User quota on /export/share_3 (/dev/dm-28)
Blocks
User ID Used Soft Hard Warn/Grace
---------- --------------------------------------------------
#0 0 0 800000 00 [--------]
#2001117 0 0 1024000 00 [--------]
Group quota on /export/share_3 (/dev/dm-28)
Blocks
Group ID Used Soft Hard Warn/Grace
---------- --------------------------------------------------
#0 0 0 0 00 [--------]
(group 2000514 is not listed since it does not have a hard limit and
its quota is not used by any file)

<=== This is the problem. It's not clear where this hard limit
came from
