Plesk 12.x / Linux :: CentOS 7 - Hard Disk Quota Is Not Supported Due To Configuration Of Server File System

I have a new CentOS 7, with Plesk 12, CentOS 7 by default has XFS filesystem.

I try migrate sites from another Plesk Server but Plesk agent say: "hard disk quota is not supported due to configuration of server file system" (my CentOS 7)

My CentOS7:

CentOS Linux 7.0.1406 64 bits
Plesk 12.0.36

My fstab

[root@ns ~]$ cat /etc/fstab
/dev/mapper/centos-root / xfs defaults,usrquota,grpquota 1 1
UUID=ba391bd5-786c-4ae7-8bbd-f36f831ae6eb /boot xfs defaults 1 2
/dev/mapper/centos-swap swap swap defaults 0 0

I added "usrquota,grpquota", then mount -o remount / ; but when I try quotacheck -fmv / I gest this:

[root@ns ~]$ quotacheck -fmv /
quotacheck: Skipping /dev/mapper/centos-root [/]
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.

but quotaon command works:

[root@ns ~]$ quotaon /
quotaon: Enforcing group quota already on /dev/mapper/centos-root
quotaon: Enforcing user quota already on /dev/mapper/centos-root

The problem here is why Plesk does not recognize quotas as enabled on CentOS 7??

If I try this command it seems good:

[root@ns ~]$ /usr/local/psa/admin/sbin/usermng --isquotable
0

Also I do this:

- Disabled Selinux
- Check all packages as quota, etc.
