A.4. Enabling/Disabling Quota Enforcement

In GFS2 file systems, quota enforcement is disabled by default. To enable quota enforcement for a file system, mount the file system with the quota=on option specified.

Usage

mount -o quota=on BlockDevice MountPoint
To mount a file system with quota enforcement disabled, mount the file system with the quota=off option specified. This is the default setting. 
mount -o quota=off BlockDevice MountPoint
-o quota={on|off}
Specifies that quota enforcement is enabled or disabled when the file system is mounted.
BlockDevice
Specifies the block device where the GFS2 file system resides.
MountPoint
Specifies the directory where the GFS2 file system should be mounted.

Examples

In this example, the GFS2 file system on /dev/vg01/lvol0 is mounted on the /mygfs2 directory with quota enforcement enabled. 
# mount -o quota=on /dev/vg01/lvol0 /mygfs2
