mmdefedquota Command
.SH "Name"
.PP
\fBmmdefedquota\fR - Sets default quota limits to a file
system.
.SH "Synopsis"
.PP
\fBmmdefedquota\fR {\fB-u\fR | \fB-g\fR | \fB-j\fR}
\fIDevice\fR
.SH "Description"
.PP
Use the \fBmmdefedquota\fR command to set or change default quota
limits for new users, group 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 \fB-Q yes\fR option on the
\fBmmcrfs\fR
command or changed with the
\fBmmchfs\fR
command.
.PP
The \fBmmdefedquota\fR command displays the current values for these
limits, if any, and prompts you to enter new values using your default
editor:
.RS +3
.HP 3
\(bu Current block usage (display only)
.HP 3
\(bu Current inode usage (display only)
.HP 3
\(bu Inode soft limit
.HP 3
\(bu Inode hard limit
.HP 3
\(bu Block soft limit
.sp
Displayed in \fBKB\fR, but may be specified using \fBk\fR,
\fBK\fR, \fBm\fR, \fBM\fR, \fBg\fR, or \fBG\fR . If no
suffix is provided, the number is assumed to be in \fBbytes\fR.
.HP 3
\(bu Block hard limit
.sp
Displayed in \fBKB\fR, but may be specified using \fBk\fR,
\fBK\fR, \fBm\fR, \fBM\fR, \fBg\fR, or \fBG\fR. If no
suffix is provided, the number is assumed to be in \fBbytes\fR.

A block or inode limit of 0 indicates no limit.

The \fBmmdefedquota\fR 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.
.PP
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
\fBmmlsquota\fR command and the \fBmmrepquota\fR command are double the value reported
by the \fBls\fR command.
.PP
The EDITOR environment variable must contain a complete path name, for
example:
.sp
.nf
export EDITOR=/bin/vi

command is issued.
.SH "Examples"
.PP
To set default quotas for new users of the file system \fBfs1\fR,
issue this command:
.sp
.nf
mmdefedquota -u fs1
.fi
.sp
.PP
The system displays information in your default editor similar to:
.sp
.nf
*** Edit quota limits for USR DEFAULT entry
NOTE: block limits will be rounded up to the next multiple
         of the block size.
block units may be: K, M, or G.
fs1: blocks in use: 0K, limits (soft = 0K, hard = 0K)
inodes in use: 0, limits (soft = 0, hard = 0)
.fi
.sp
.PP
To confirm the change, issue this command:
.sp
.nf
mmlsquota -d -u
.fi
