mmdefedquota Command
Name
mmdefedquota – Sets default quota limits to a file system.
Synopsis
mmdefedquota {-u | -g | -j} Device
Description
Use the mmdefedquota command to set or change default quota limits for new users, groups, and filesets
for a file system. Default quota limits for a file system may be set or changed only if the file system was
created with the -Q yes option on the mmcrfs command or changed with the mmchfs command.
The mmdefedquota command displays the current values for these limits, if any, and prompts you to
enter new values using your default editor:
v Current block usage (display only)
v Current inode usage (display only)
v Inode soft limit
v Inode hard limit
v Block soft limit
Displayed in KB, but may be specified using k, K, m, M, g, or G . If no suffix is provided, the number is
assumed to be in bytes.
v Block hard limit
Displayed in KB, but may be specified using k, K, m, M, g, or G. If no suffix is provided, the number is
assumed to be in bytes.
Note: A block or inode limit of 0 indicates no limit.
The mmdefedquota command waits for the edit window to be closed before checking and applying new
values. If an incorrect entry is made, you must reissue the command and enter the correct values.
When setting quota limits for a file system, replication within the file system should be considered. GPFS
quota management takes replication into account when reporting on and determining if quota limits have
been exceeded for both block and file usage. In a file system that has either type of replication set to a
value of two, the values reported on by both the mmlsquota command and the mmrepquota command
are double the value reported by the ls command.
The EDITOR environment variable must contain a complete path name, for example:
export EDITOR=/bin/vi
Parameters
Device
Options
The device name of the file system to have default quota values set for.
File system names need not be fully-qualified. fs0 is just as acceptable as /dev/fs0.
-g Specifies that the default quota value is to be applied for new groups accessing the specified file
system.
-j Specifies that the default quota value is to be applied for new filesets in the specified file system.
