Creating file system quota reports
You can have GPFS prepare a quota report for a file system using the mmrepquota command. This lists:
1. Number of files used
2. Amount of disk space used
3. Current quota limits
4. In doubt quotas (disk space allocated but currently unaccounted for)
5. Grace period allowance to exceed the soft limit
6. Whether the quotas have been explicitly set (e), are default values (d), or initial values (i). The entry
type also indicates whether or not default quotas are enabled for the file system (default on or default
off).
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
and the values used to determine if quota limits have been exceeded will be double the value reported by
the ls command.
Specify whether you want to list only user quota information (-u flag), group quota information (-g flag), or
fileset quota information (-j flag) in the mmrepquota command. The default is to summarize all three
quotas. If the -e flag is not specified, there is the potential to display negative usage values as the quota
server may process a combination of up-to-date and back-level information. When issuing the
mmrepquota command on a mounted file system, negative in doubt values may be reported if the quota
server processes a combination of up-to-date and back-level information. This is a transient situation and
may be ignored.
To list the group quotas (-g option) for all file systems in the cluster (-a option), and print a report with
header lines (-v option), enter:
mmrepquota -g -v -a

See the “mmrepquota Command” on page 246 for complete usage information.
Restoring quota files
User, group, and fileset quota files can be restored from a backup copy of the original quota file. When
restoring quota files, the backup file must be in the root directory of the file system. If a backup copy does
not exist, an empty file will be created when the mmcheckquota command is issued.
The user, group, or fileset files can be restored from backup copies by issuing the mmcheckquota
command with the appropriate options.
