This page contains information about quota limits on the GPFS. Quotas are enabled to control the file system usage.
You can display the user quota information with the mmlsquota command. It will inform you about quota limits (block quota and file quota) and the current usage on the filesystem:
$ mmlsquota Block Limits | File Limits Filesystem type KB quota limit in_doubt grace | files quota limit in_doubt grace Remarks gpfs USR 28292096 3221225472 4294967296 0 none | 136704 2000000 3000000 0 none
Add the --block-size option to specify the unit (K , M, G, T) in which the number of blocks is displayed:
$ mmlsquota --block-size=G Block Limits | File Limits Filesystem type GB quota limit in_doubt grace | files quota limit in_doubt grace Remarks gpfs USR 27 3072 4096 0 none | 136704 2000000 3000000 0 none
The output shows the quotas in the file system GPFS for the user who issued the command. The quotas are set to a soft limit of 3072 GB, and a hard limit of 4096 GB. 27 GB is currently allocated to the user. An in_doubt value greater than zero means that the quota system has not yet been updated as to whether the space that is in doubt is still available or not. If the user exceeds the soft limit, the grace period will be set to one week. If usage is not reduced to a level below the soft limit during that time, the quota system interprets the soft limit as the hard limit and no further allocation is allowed. The user can reset this condition by reducing usage enough to fall below the soft limit. The maximum amount of disk space the user can accumulate during the grace period is defined by the hard limit. The same information is also displayed for the file limits (number of files).
You can display the the group quota of your own group using the -g option:
$ mmlsquota -g id --block-size T Disk quotas for group id (gid 1001): Block Limits | File Limits Filesystem type TB quota limit in_doubt grace | files quota limit in_doubt grace Remarks gpfs GRP 1 15 16 0 none | 2232666 10000000 12000000 0 none
