-Is nonoperational.
+Checkout the specified volume from the running fileserver. This ensures that

=item B<-vnode>
Displays statistics about the volume header of each volume, in addition to
the default output.
-=item B<-sizeOnly>
+=item B<-sizeonly>
Displays a single line of output for each volume, reporting the size of
various structures associated with it. The default output is suppressed
By default, the command produces several line of statistics for each
volume. Adding other options produces or substitutes additional
-information as described in L<OPTIONS>. The output is intended for
+information as described in L</OPTIONS>. The output is intended for
debugging purposes and is meaningful to someone familiar with the internal
structure of volume headers.
