xfs_quota returns "limits: Function not implemented"

Environment

SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Server 12

Situation

Errors are observed when setting project quotas on an XFS filesystem

server:~ # mount | grep xfs
/dev/system/var on /var type xfs (rw,relatime,attr2,inode64,noquota)
/dev/system/SUSEtest on /root/SUSEtest type xfs (rw,relatime,attr2,inode64,prjquota)

server:~ # mount -o pquota /dev/system/SUSEtest /root/SUSEtest/

server:~ # xfs_quota -x -c "report -h" /root/SUSEtest/

server:~ # cat /etc/projid 
test:10

server:~ # cat /etc/projects 
10:/root/SUSEtest

server:~ # xfs_quota -x -c "limit -p bhard=120m test"
xfs_quota: cannot set limits: Function not implemented

server:~ # xfs_quota -x -c "report -h" /root/SUSEtest/
Project quota on /root/SUSEtest (/dev/mapper/system-SUSEtest)
                        Blocks              
Project ID   Used   Soft   Hard Warn/Grace   
---------- --------------------------------- 
test            0      0   120M  00 [------]

Resolution

Specify a specific directory to which quotas will be applied to avoid seeing the error.

server:~ # xfs_quota -xc 'limit -p bhard=100m test' /root/SUSEtest

server:~ # xfs_quota -x -c "report -h" /root/SUSEtest/
Project quota on /root/SUSEtest (/dev/mapper/system-SUSEtest)
                        Blocks              
Project ID   Used   Soft   Hard Warn/Grace   
---------- --------------------------------- 
test            0      0   100M  00 [------]

Cause

The xfs_quota command will return the "xfs_quota: cannot set limits: Function not implemented" error for each XFS filesystem mounted that has the "noquota" attribute.

Engineering is still looking into why errors are reported for the "noquota" XFS filesystems.
