Here is what I have:
/etc/fstab
----
LABEL=/home /home xfs defaults,usrquota 1 2
----
once usrquota is in fstab, unmount and mount again /home; then you will see
# mount | grep home
/dev/sdb1 on /home type xfs (rw,usrquota)
(or similar)
To set quotas once for all users (and any users added in a future):
xfs_quota -x -c "limit bsoft=9g bhard=10g -d" /home
or make some individual quota different than already set for everyone:
xfs_quota -x -c "limit bsoft=7g bhard=8g valeri" /home
Here you should be done. In fact, you will not see quota status,
occupancies of given user until the user writes something after the
quotas had been set.
I hope, this helps.
