14The \fBmmrepquota\fR command reports file system usage and quota
15information for a user, group, and fileset.
16.PP
17If neither the \fB-g\fR, \fB-j\fR nor \fB-u\fR option is
18specified, then user, group and fileset quotas are listed.
19.PP
20If the \fB-a\fR option is not specified, \fIDevice\fR must be the
21last parameter entered.

23For each file system in the cluster, the \fBmmrepquota\fR command

105.PP
106Because the sum of the in-doubt value and the current usage may not exceed the
107hard limit, the actual block space and number of files available to the user, 
108group, or fileset may be constrained by the \fIin-doubt\fR value. If the
109\fIin-doubt\fR value approach a significant percentage of the quota, run
110the
111\fBmmcheckquota\fR command to account for the
112lost space and files.
113.PP
114GPFS quota management takes replication into account when reporting on and
115determining if quota limits have been exceeded for both block and file
116usage. In a file system that has either type of replication set to a
117value of two, the values reported on by both the \fBmmlsquota\fR command and the \fBmmrepquota\fR
118command are double the value reported by the \fBls\fR command.
119.PP
120When issuing the \fBmmrepquota\fR command on a mounted file system,
121negative in-doubt values may be reported if the quota server processes a
122combination of up-to-date and back-level information. This is a
123transient situation and may be ignored.
124.PP
125When a quota management enabled file system is SANergy exported, the block
126usage accounting of a file accessed through SANergy include the blocks
127actually used by the file and the extra blocks temporarily allocated (hyper
128allocation) by SANergy. Hyper allocation is a SANergy performance
129feature and can be tuned using SANergy configuration tools. For more
130information, see \fITivoli SANergy: Administrator's Guide\fR at
131publib.boulder.ibm.com/tividd/td/SANergy2.2.4.html.
