Make sure, that you have user quota (uqota) and project quota (pquota) set as options on the chosen mount point in /etc/fstab. For example:
/dev/vdb1 /var/backup xfs noatime,uquota,pquota 0 0
Remount the file system /var/backup and check, if the quotas have the desired values:
xfs_quota -x
Some important notes:
# The '''quotacheck''' command has no effect on XFS filesystems. The first time quota accounting is turned on (at mount time), XFS does an automatic quotacheck internally; afterwards, the quota system will always be completely consistent until quotas are manually turned off.
# There is no need for quota file(s) in the root of the XFS filesystem.
