mmdefquotaon Command
Name
mmdefquotaon - Activates default quota limit usage for a file system.
Synopsis
mmdefquotaon [-u] [-g] [-j] [-v] [-d] {Device [Device... ] | -a}
Description
The mmdefquotaon command activates default quota limits for a file system. If default quota limits are not
applied, new users, groups, or filesets for that file system will have a quota limit of 0, indicating no limit.
To use default quotas, the file system must have been created or changed with the -Q yes option. See the
mmcrfs and mmchfs commands.
If neither the -u, -j or the -g option is specified, the mmdefquotaon command activates all default quota
limits.
If the -a option is not used, Device must be the last parameter specified.
Default quotas are established for new users, groups of users or filesets by issuing the mmdefedquota
command. Under the -d option, all users without an explicitly set quota limit will have a default quota limit
assigned.
Parameters
Device
Options
The device name of the file system to have default quota values activated.
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.
-a Activates default quotas for all GPFS file systems in the cluster. When used in combination with
the -g option, only group quotas are activated. When used in combination with the -u or -j options,
only user or fileset quotas, respectively, are activated.
-d Specifies that existing users, groups of users, or filesets with no established quota limits will have
default quota values assigned when the mmdefedquota command is issued.
If this option is not chosen, existing quota entries remain in effect and are not governed by the
default quota rules.
-g Specifies that only a default quota value for group quotas is to be activated.
-j Specifies that only a default quota value for fileset quotas is to be activated.
-u Specifies that only a default quota value for users is to be activated.
-v Prints a message for each file system in which default quotas are activated.
Exit status
0 Successful completion.
nonzero A failure has occurred.
