quota_account tunable parameter to 0. This must be done on each node and after each mount.

(The 0 setting is not persistent across unmounts.) Quota accounting can be enabled by setting

the quota_account tunable parameter to 1.

To see the current values of the GFS tunable parameters, including quota_account, you can

use the gfs_tool gettune, as described in Section 4, “Displaying GFS Tunable Parameters”.

Usage

gfs_tool settune MountPoint quota_account {0|1}

MountPoint

Specifies the GFS file system to which the actions apply.

quota_account {0|1}

0 = disabled

1 = enabled

Comments

To enable quota accounting on a file system, the quota_account parameter must be set back

to 1. Afterward, the GFS quota file must be initialized to account for all current disk usage for

users and groups on the file system. The quota file is initialized by running: gfs_quota init -f

MountPoint.

Note

Initializing the quota file requires scanning the entire file system and may take a

long time.

To see the current values of the GFS tunable parameters, including quota_account, you can

use the gfs_tool gettune, as described in Section 4, “Displaying GFS Tunable Parameters”.

Examples

This example disables quota accounting on file system /gfs on a single node.

gfs_tool settune /gfs quota_account 0

This example enables quota accounting on file system /gfs on a single node and initializes the

quota file.
