.CMD_UPDATE_FILEMAP
.br
Update a group of \fBdmstats\fP regions specified by \fBgroup_id\fP,
that were previously created with \fB\-\-filemap\fP. This will add
and remove regions to reflect changes in the allocated extents of
the file on-disk, since the time that it was crated or last updated.
Use of this command is not normally needed since the \fBdmfilemapd\fP
daemon will automatically monitor filemap groups and perform these
updates when required.
If a filemapped group was created with \fB\-\-nominitor\fP, or the
daemon has been killed, the \fBupdate_filemap\fP can be used to
manually force an update.
