Deactivating quota limit checking

During normal operation, there is no need to deactivate quota enforcement. The only reason you might have to deactivate quota enforcement is when users are denied allocation that their quotas should allow, due to loss of quota information during node failure.

If this occurs, use the mmcheckquota command after reactivating quotas to reconcile allocation data. When quota enforcement is deactivated, disk space and file allocations are made without regard to limits.

The mmquotaoff command is used to deactivate quota limit checking. Specify the file system name and whether user, group, or fileset quotas, or any combination of these three, are to be deactivated. If you want all types of quotas deactivated, specify only the file system name.

For example, to deactivate only user quotas on the file system fs1, enter:

mmquotaoff -u fs1

To confirm the change, enter:

mmlsfs fs1 -Q

The system displays output similar to:

flag value          description
---- -------------- --------------------
 -Q  group;fileset  Quotas enforced

For complete usage information, see mmquotaoff command and mmlsfs command.
