.SH DESCRIPTION
.TP
.BR "lfs quota " [ \fIMOUNT_POINT " ...]"
Display disk usage and limits for individual users, groups, and projects for
each MOUNT_POINT.
An asterisk is displayed when the quota is exceeded.
By default the statistics for the entire filesystem are displayed but
individual MDTs and OSTs can be specified with the
.B --ost
or
.B --mdt
options. A user, group, or project ID can be specified.
If user, group, and project are omitted, quotas for the
current uid/gid/projid are shown.
If no
.I MOUNT_POINT
is specified, quotas for all Lustre mountpoints will be shown.
.TP
.BR "lfs quota " { -U | -G | -P "} [" \fIMOUNT_POINT " ...]"
Display default quota values for users, groups, or projects.
This command requires superuser permissions.
.TP
.BR "lfs quota -a" " {" -u | -g | -p "} [" -n "] [" --show-root "] [" \fIMOUNT_POINT " ...]
Display disk usage and limits for all users, groups, or projects that exist
across all mounted filesystems.
.B -n
display the numeric value of the quota IDs instead of its name
.B --start-qid
and
.B --end-qid
display the value of the quota IDs only in the select range.
.B --show-root
display root quota entry.
.TP
.BR "lfs quota -t" " {" -u | -g | -p "} [" \fIMOUNT_POINT " ...]"
Display grace times for users, groups, or projects.
Time values use the
.RB \(dqXX w XX d XX h XX m XX s \(dq
format, which specifies weeks, days, hours, minutes, seconds.
