Thread-topic: weird quota issue
HI everyone, long time xfs/quota user with new server and problem
hardware is HP BL460 G7 blade, qlogic fiber channel and 3Par 7200 storage
3 16TB vols exported from 3Par to server via FC. These are thin volumes, but 
plenty of available backing storage.

Server runs current patched CentOS 6.6
kernel 2.6.32-504.3.3.el6.x86_64
xfsprogs 2.1.1-16.el6
Default mkfs.xfs options for volumes

mount options for logical volumes  home_lv 39TB imap_lv 4.6TB
/dev/mapper/irphome_vg-home_lv on /home type xfs 
(rw,delaylog,inode64,nobarrier,logbsize=256k,uquota,prjquota)
/dev/mapper/irphome_vg-imap_lv on /mail type xfs 
(rw,delaylog,inode64,nobarrier,logbsize=256k,uquota,prjquota)

Users are from large AD via winbind set to not enumerate. I saw the bug with 
xfs_quota report not listing winbind defined user names. Yes this happens to me.
I can assign project quota to smaller volume. xfs_quota will not report it. I 
cannot assign a project quota to larger volume. I get this error: xfs_quota: 
cannot set limits: Function not implemented.

xfs_quota -x -c 'report -uh' /mail
User quota on /mail (/dev/mapper/irphome_vg-imap_lv)
                        Blocks
User ID      Used   Soft   Hard Warn/Grace
---------- ---------------------------------
root         2.2G      0      0  00 [------]

[xfs_quota -x -c 'report -uh' /home

nothing is returned

I can set user and project quotas on /mail but cannot see them. I have not 
tested them yet.
I cannot set user or project quotas on /home.
At one time I could definitely set usr quotas on /home. I did so and verified 
it worked.

Any ideas what is messed up on the /home volume?
