-Is nonoperational.
+Checkout the specified volume from the running fileserver. This ensures that
+the fileserver or other processes will not be modifying volume metadata at the
+same time we are trying to read it, leading to invalid or incorrect results.
=item B<-vnode>
When combined with the B<-vnode> flag, displays a change, modification,
and access timestamp for each of the large vnode and small vnode tables.
-=item B<-part> <I<partition name>>+
+=item B<-part> <I<partition name or id>>+
Specifies the partition that houses each volume for which to produce
-output. Use the format F</vicepI<xx>>, where I<xx> is one or two lowercase
+output. Use the format F</vicepI<xx>> or I<xx>, where I<xx> is one or two lowercase
letters. This argument can be omitted if the current working directory is
the mount location for an AFS server partition; it is not the mount
location for an AFS server partition, the command produces output for
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
only orphaned vnodes (vnodes that have no parent). If there are none, the
tables are empty (only the headers appear).
+=item B<-filenames>
+
+When combined with the B<-vnode> flag, adds the full path and file name of the
+C<namei> file which stores the vnode data to each vnode entry in the large vnode
+and small vnode tables. This option is only available on fileservers which use
+the C<namei> storage format for storing data.

=item B<-help>
Prints the online help for this command. All other valid options are
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.
