xfs quota command examples

xfs_quota – manage use of quota on XFS filesystems

Enabling quota enforcement on an XFS filesystem (restrict a user to a set amount of space).

# mount -o uquota /dev/xvm/home /home
# xfs_quota -x -c 'limit bsoft=500m bhard=550m tanya' /home
# xfs_quota -x -c report /home

Enabling project quota on an XFS filesystem (restrict files in log file directories to only using 1 gigabyte of space).

# mount -o prjquota /dev/xvm/var /var
# echo 42:/var/log >> /etc/projects
# echo logfiles:42 >> /etc/projid
# xfs_quota -x -c 'project -s logfiles' /var
# xfs_quota -x -c 'limit -p bhard=1g logfiles' /var

Same as above without a need for configuration files.

# rm -f /etc/projects /etc/projid
# mount -o prjquota /dev/xvm/var /var
# xfs_quota -x -c 'project -s -p /var/log 42' /var
# xfs_quota -x -c 'limit -p bhard=1g 42' /var
