=head1 NAME

vos size - Computes the size of a volume

=head1 SYNOPSIS

=for html
<div class="synopsis">

B<vos size> S<<< [B<-cell> <I<cell name>>] >>> [B<-dump>]
    [B<-encrypt>] [B<-help>] [B<-id>] <I<volume name or id>>
    [B<-localauth>] [B<-noauth>]

    S<<< [B<-server> <I<machine name>>] >>>
    S<<< [B<-time> <I<dump from time>>] >>> [B<-verbose>]

=for html
</div>

=head1 DESCRIPTION

The B<vos size> command shows the size of a volume for backup
purposes. The size of dump may differ from the volume size as reported
by L<vos_examine(1)> or L<fs_listquota(1)>. The size is reported in bytes.


=head1 OPTIONS

=over 4

=item B<-cell> <I<cell name>>

The cell in which the volume resides, if it's not in the current cell.

=item B<-dump>

Show the size of the volume dump for the specified volume.

=item B<-encrypt>

Encrypt the commands.

=item B<-help>

Display a brief help message.

=item B<-id> <I<volume name or id>>

The name or id of the volume of which to determine the size.

=item B<-localauth>

Executes the command using the server's credentials. This option can
only be used on an AFS server in the same cell as the volume being
sized.

=item B<-noauth>

Executes the command without any privileges. See L<vos(1)> for more
info. This should not be used with the B<-localauth> option.

=item B<-partition> <I<partition name>>

The partition on which the volume resides.

=item B<-server> <I<machine name>>

The server on which the volume resides.

=item B<-time> <I<dump from time>>

Show the size of the incremental volume dump from the time specified.

=item B<-verbose>

Show more output about what's going on.

=back

=head1 OUTPUT

The command shows the name of the volume and the size in bytes.

=head1 EXAMPLES

=over 4

=item C<vos size root.cell -dump>

   Volume: root.cell
   dump_size: 2562

=item C<vos size root.cell -dump -verbose>

   Volume: root.cell
   Starting transaction on volume 536870915... done
   Getting size of volume on volume 536870915... done
   Ending transaction on volume 536870915... done
   dump_size: 2562

                            OpenAFS Man Pages

Overview

  This directory contains the POD source and (in releases) the generated
  man pages for OpenAFS commands and files.  The man pages are based on
  the original IBM AFS Administration Reference manual, released with the
  rest of AFS under the IBM Public License 1.0.  They were converted from
  HTML to POD, editing, and are currently maintained in POD.

  The man pages are very much a work in progress.  The original source
  material dated from IBM's public release of AFS, and many changes since
  made in OpenAFS are not reflected in the man pages.  Help and
  contributions are actively solicited.  Please see "How You Can Help"
  below for more information.

  The long-term goal is for every command shipped with OpenAFS and every
  configuration or data file written or read by OpenAFS to have its own
  man page.  Section one is used for commands that don't require special
  privileges, section eight for commands for AFS administrators and local
  system administrators, and section five for file formats and
  configuration files, with the exception that command suites are kept
  together (so, for instance, all fs commands are documented in section
  one even though some of them are only usable by a local system
  administrator).

  The OpenAFS man pages are discussed on the openafs-doc mailing list at
  openafs.org.  If you plan on contributing to the man page project,
  please join that mailing list and send suggestions, patches, and
  contributions there.  The coordinator of the OpenAFS man page project is
  Russ Allbery <rra@stanford.edu>; feel free to contact me directly with
  questions (although using the mailing list is generally better and will
  probably result in a faster response).

POD and Man Page Generation

  The OpenAFS man pages are maintained in POD (Plain Old Documentation),
  the documentation system originally developed for Perl.  This is not an
  uncontroversial choice, since POD isn't as rich and full-featured as
  other possible alternatives such as Docbook RefEntry.  On the other
  hand, POD is very close to plain text, can be easier to edit and
  maintain for those not familiar with the documentation format, and has
  more mature tools for conversion to formatted man pages, an output
  format that is particularly important on Unix/Linux.  There are many
  good arguments either way, and fundamentally the decision was made to
  use POD because I prefer it and I'm volunteering to write and edit the
  pages and maintain them going forward.

  To convert the POD source to formatted man pages, you need the pod2man
  utility.  This utility has come with Perl for many years, so if you have
  Perl installed, you almost certainly have some version of it available.
  For the best results, install Pod::Simple 3.03 or later and podlators
  2.00 or later from CPAN and use that pod2man, but the results from the
  pod2man that comes with Perl 5.8 or later will be very good.  If you are
  using earlier versions of Perl, the output should be adequate and
  readable but may contain some formatting glitches.

  Preformatted man pages will be included in distribution tarballs, but
  those man pages may be generated with older versions of the conversion
  utilities.  To regenerate the man pages, run regen.sh at the top of the
  OpenAFS source tree (this will also regenerate the Autoconf scripts).

  Conversion to HTML can be done via any of the POD to HTML converters
  available (there are many of them), but for best results (particularly
  for crosslinks), use the generate-html script in this directory.  You
  will need to have the Pod::Simple Perl module installed.  If your Perl
  is not in /usr/bin, run generate-html explicitly with:

      perl generate-html

  It will generate HTML pages in the html subdirectory of this directory.

Formatting Standards

  Each command or configuration file should have a separate man page in a
  separate POD file.  Command suites (fs, pts, vos, etc.) should have an
  overview man page that lists the available subcommands by category,
  documents common options, and discusses the general use of the suite.
  Then, each operation code in the suite should have a separate man page,
  named after the command with the space between the command suite and the
  operation code replaced with an underscore.

  All man pages must follow the standard layout for man page sections and
  formatting.  The best general reference is the pod2man man page,
  although the sections used for OpenAFS man pages aren't quite the same
  (see below).  In particular, please use the following markup:

   * B<> for all commands, command/operation code pairs, and options.
   * F<> for file names, directory names, partition names, or paths.
   * <I<>> for user-provided arguments (note the surrounding <>).
   * I<> for terms being defined or titles of works.
   * C<> for command examples, ACL characters, and example arguments.

  Also see the afs(1) man page for general rules about how OpenAFS man
  pages are formatted and for standard terminology to use when talking
  about OpenAFS commands.

  Each man page should have the following sections:  NAME, SYNOPSIS (for
  commands only), DESCRIPTION, CAUTIONS, OPTIONS (for commands only),
  OUTPUT (where appropriate), EXAMPLES, PRIVILEGE REQUIRED (for commands
  only), SEE ALSO, and COPYRIGHT, generally in that order.  Be sure to
  include the IBM copyright in all man pages derived from the original IBM
  documentation.  If you wrote the man page yourself, please include your
  own copyright and a statement that the man page is released under the
  IBM Public License Version 1.0, or under some other license that is
  sufficiently compatible that we can use your work.  If you use another
  license and that license isn't "public domain," you have to give the
  full license text in the man page; please don't use a license so long
  that this is annoying.

  The SYNOPSIS section should start with the full command name and the
  full names of all options, and then have a second section showing the
  most abbreviated form of the command name and its options.  If the
  command has aliases, it should have additional sections showing those.
  Please be sure to follow all of the formatting requirements for
  commands, flags, and options.  Enclose optional arguments in [] and
  choices in () separated by |.  Command names and options are marked up
  with B<> as mentioned above; all other literal text that should be
  entered on the command line gets no markup.

  References to other OpenAFS man pages should be given as L<afs(1)>.
  Other man pages should be noted like df(1), without the L<> markup.
  References to functions should be noted like function() with the
  trailing parens.  The POD converters know how to format these sorts of
  references appropriately.  References to other sections in the same page
  should be given as L<SECTION>.

  Command and output examples should be indented three spaces.  Commands
  entered by the user should be given on a line beginning with %.  If the
  command doesn't fit in 80 columns, put in a backslash at a logical break
  point and continue the line with an additional four spaces of
  indentation.  Output examples may be wrapped with an additional four
  spaces of indentation but probably shouldn't be; not wrapping makes the
  man page look somewhat less readable, but is less confusing when
  converted to other formats such as HTML.

  POD does not allow markup in verbatim paragraphs (which are indicated by
  indenting the first line of the paragraph), so metasyntactic variables
  in examples should be shown like <this> with simple angle brackets
  surrounding the variable.  For consistency in formatting, references to
  those variables should be formatted the same in following text.

How You Can Help

  The OpenAFS man page project is just starting, and a lot of work remains
  to be done.  Any and all contributions are greatly appreciated.  What
  follows is a list of the ways that you can help in order of increasing
  helpfulness.  If you only have time to do something near the top of the
  list, please do; every little bit helps.  If you have more time and can
  do something closer to the bottom of the list, that's even better and
  your contribution can be included more rapidly.

   * Point out places OpenAFS behavior has changed since the documentation
     was written, or point out missing documentation.  Please check the
     "Known Problems" list below to make sure that the item is not already
     noted.

   * Point out formatting problems, typos, formatting inconsistency, and
     other markup or language problems in the man pages.

   * Provide missing documentation in some form (text, HTML, whatever)
     that can be incorporated into the man pages, or detailed explanations
     of how the existing documentation needs to be changed to match what
     the tools actually do.

   * Provide missing man pages in POD format suitable for immediate
     inclusion in the documentation.  Please try to follow the formatting
     standards documented in the "Formatting Standards" section above, and
     look at the existing man pages for examples.

   * Provide patches against the POD source that correct formatting
     problems, typos, formatting inconsistencies, or other markup or
     language problems with the man pages.

   * Provide patches against the POD source that add or correct the
     documentation of commands or file formats for changes in OpenAFS.

  Please send contributions either to the openafs-doc list or as bugs
  filed via the bug reporting instructions at <http://www.openafs.org/>.
  If you do submit a bug, please send me a note at rra@stanford.edu with
  the bug number so that I'm aware of it, as I don't always notice new
  bugs.

Known Problems

  The current man pages have the following known deficiencies.  Please
  don't just report the deficiency again, but any contributions towards
  fixing it are greatly appreciated.

   * The following installed commands have no man pages:

       bos_util
       copyauth
       flushall (windows only)
       fs getcalleraccess
       fs getcrypt -- fixed
       fs listaliases -- fixed
       fs newalias -- fixed
       fs rxstatpeer
       fs rxstatproc
       fs setcbaddr
       fs setcrypt -- fixed
       kseal
       pts interactive
       pts quit
       pts sleep
       pts source
       read_tape
       restorevol
       rmtsysd
       vldb_convert
       vos changeloc
       vos clone
       vos convertROtoRW
       vos copy
       vos shadow
       vos size -- fixed
       vsys

   * The following configuration files have no man pages:

       CellAlias -- fixed.

   * klog.krb, pagsh.krb, and tokens.krb need to be listed as alternative
     names in the NAME line of the non-.krb man pages, links should be
     installed on man page installation, and the behavior of pagsh.krb
     should be documented in the pagsh man page.

   * Some of the documentation in fs getserverprefs needs minor updates to
     reflect what happens in the dynroot case.

   * fs sysname documentation needs to include the possibility of setting
     multiple sysnames and the resulting behavior.

   * Done?: The afsd man page is horribly out of date.  It doesn't explain
     dynroot, many options are missing, and some of the options described
     are no longer valid.  It also still assumes that -settime is the
     default and says that the system must be rebooted after shutdown,
     which isn't the case at least on Linux.

   * bos listkeys and the KeyFile man page assume that you're using the
     kaserver.

   * I'm fairly sure that the fileserver man page no longer documents all
     of the fileserver options.

   * There are lingering references to AFS Development or AFS Product
     Support in descriptions of options that one should generally not
     use.  Also, all of the manual references refer to the "IBM" manual.
     We should decide how to handle this terminology-wise.

   * The salvager actually creates a bunch of SalvageLog files and then
     combines them, but the SalvageLog man page doesn't reflect this.

   * The CellServDB documentation hasn't been updated for -dynroot.

   * In the suite introduction pages (pts, vos, etc.), each of the
     subcommands in the initial list should be a link to the relevant
     page in the HTML output.  This has been done for the fs intro page
     and the same transform needs to be applied to the other pages.  See
     the fs intro page for the details.

   * The references to the other OpenAFS manuals, such as the Quick Start
     guide and the Admin Guide, should be links, probably to the documents
     on openafs.org.

   * There's no mention of the Kerberos v5 support.  At least, we need
     some disclaimers under klog and friends talking about sites without
     kaserver (and possibly without fakeka), and deprecation warnings
     on the .krb varient commands.

   * We need a way to add links to other man pages (kinit most notably)
     without creating dangling links in the HTML output.  This probably
     means that the HTML conversion script needs to generate at startup
     a list of all valid man page link targets and not linkify the ones
     that don't match a valid target.

   * Provide a way to substitute the correct paths into the HTML output
     from Autoconf results.

   * Currently, the man pages are built by regen.sh, which is somewhat
     annoying since it takes a long time.  Figure out how better to do this
     during the release process so that end users don't have to have
     pod2man.

   * Review the sections used for all man pages against what directories
     the commands are installed into.  (In some cases, it may be better to
     change the directory than the section of the man page.)

  If you notice other problems, please send them to the openafs-doc list
  even if you don't have time to fix them.  Someone else might, and we
  want to track all of the issues.
