.BR "lfs setquota " {\fB-u|-g|-p\fR}
.B -p|--project <\fIprojid\fR>
Set project quota for \fIprojid\fR.
.TP
+.B -d|--default
+Set user/group/project to use the default quota limits.
+.TP
.B -b|--block-softlimit <\fIblock-softlimit\fR>
Specify block softlimit, zero means unlimited.
.TP
grant each user a larger hard quota limit. The soft quota limit is reset once \
the user, group, or project reduces their space usage below the soft quota \
limit. Grace time is specified in "XXwXXdXXhXXmXXs" format or as an integer \
-seconds value.
+seconds value, and the maximum is 2^48 - 1 seconds.
.TP
.B -t
Set quota grace times.
.TP
.B -i|--inode-grace <\fIindoe-grace\fR>
Specify grace time for inode quota.
+.PP
+.BR "lfs setquota " {\fB-U|--default-usr|-G|--default-grp|-P|--default-prj\fR}
+.TP
+Command sets the filesystem default limits for user,group,project quotas, \
+if set, users/groups/projects without specific quota setting will use \
+default quota limits automatically.
+.TP
+.B -U|--default-usr
+Set default user quota limit.
+.TP
+.B -G|--default-grp
+Set default group quota limit.
+.TP
+.B -P|--default-prj
+Set default project quota limit.
