mmquotaoff command

Deactivates quota limit checking.

Synopsis

mmquotaoff [-u] [-g] [-j] [-v] {Device [Device ...] | -a}

Availability

Available on all IBM Spectrum Scale editions.

Description

The mmquotaoff command disables quota limit checking by GPFS.

If none of: -u, -j or -g is specified, the mmquotaoff command deactivates quota limit checking for users, groups, and filesets.

If the -a option is not specified, Device must be the last parameter entered.

Parameters

Device [Device ...]: The device name of the file system to have quota limit checking deactivated.
If more than one file system is listed, the names must be delimited by a space. File system names need not be fully-qualified. fs0 is just as acceptable as /dev/fs0.

Options

-a: Deactivates quota limit checking for all GPFS file systems in the cluster. When used in combination with the -g option, only group quota limit checking is deactivated. When used in combination with the -u or -j options, only user or fileset quota limit checking, respectively, is deactivated.
-g: Specifies that only group quota limit checking is to be deactivated.
-j: Specifies that only quota checking for filesets is to be deactivated.
-u: Specifies that only user quota limit checking is to be deactivated.
-v: Prints a message for each file system in which quotas are deactivated.

Exit status

0: Successful completion.
nonzero: A failure has occurred.

Security

You must have root authority to run the mmquotaoff command.

The node on which the command is issued must be able to execute remote shell commands on any other node in the cluster without the use of a password and without producing any extraneous messages. For more information, see Requirements for administering a GPFS file system.

GPFS must be running on the node from which the mmquotaoff command is issued.

Examples

To deactivate user quota limit checking on file system fs0, issue this command:
```
mmquotaoff -u fs0
```
To confirm the change, issue this command:
```
mmlsfs fs0 -Q

```
To deactivate group quota limit checking on all file systems, issue this command:
```
mmquotaoff -g -a
```
To confirm the change, individually for each file system, issue this command:
```
mmlsfs fs2 -Q
```
The system displays information similar to:
```
flag value          description
---- -------------- -----------------
 -Q  user;fileset   Quotas enforced
```
To deactivate all quota limit checking on file system fs0, issue this command:
