mmdefquotaoff – Deactivates default quota limit usage for a file system.
Synopsis
mmdefquotaoff [-u] [-g] [-j] [-v] ] {Device [Device...] | -a}
Description
The mmdefquotaoff command deactivates default quota limits for file systems. If default quota limits are
deactivated, new users or groups for that file system will then have a default quota limit of 0, indicating no
limit.
If neither the -u, -j or the -g option is specified, the mmdefquotaoff command deactivates all default
quotas.
If the -a option is not used, Device must be the last parameter specified.
Parameters

Options
The device name of the file system to have default quota values deactivated.

need not be fully-qualified. fs0 is just as acceptable as /dev/fs0.
-a Deactivates default quotas for all GPFS file systems in the cluster. When used in combination with
the -g option, only group quotas are deactivated. When used in combination with the -u or -j
options, only user or fileset quotas, respectively, are deactivated.
-g Specifies that default quotas for groups are to be deactivated.
