Russ Allbery e3dfba8e6c man-page-conversion-20051208
This is the initial conversion of the AFS Adminstrators Reference into POD
for use as man pages.  The man pages are now generated via pod2man from
regen.sh so that only those working from CVS have to have pod2man
available.  The Makefile only installs.  The pages have also been sorted
out into pod1, pod5, and pod8 directories, making conversion to the right
section of man page easier without maintaining a separate list and allowing
for names to be duplicated between pod5 and pod1 or pod8 (which will likely
be needed in a few cases).

This reconversion is done with a new script based on work by Chas Williams.
In some cases, the output is worse than the previous POD pages, but this is
a more comprehensive conversion.

This is only the first step, and this initial conversion has various
problems.  In addition, the file man pages that didn't have simple names
have not been converted in this pass and will be added later.  Some of the
man pages have syntax problems and all of them have formatting errors.  The
next editing pass, coming shortly, will clean up most of the remaining
mess.

=head1 NAME
vos listvol - Displays information from a volume header
=head1 SYNOPSIS
B<vos listvol -server> <I<machine name>> [-partition <I<partition name>>]
[B<-fast>] [B<-long>] [B<-quiet>] [B<-extended>] [B<-cell> <I<cell name>>]
[B<-noauth>] [B<-localauth>] [B<-verbose>] [-help]
B<vos listvo -s> <I<machine name>> [B<-p> <I<partition name>>] [B<-f>] [-lon]
[B<-q>] [B<-e>] [B<-c> <I<cell name>>] [B<-n>] [B<-loc>] [B<-v>] [B<-h>]
=head1 DESCRIPTION
The vos listvol command formats and displays the following
information from the volume header of each specified volume: volume
name, volume ID, volume type, size, and status at the server. The
actual information displayed depends on the combination of arguments supplied
when the command is issued. To display volume header information for
various numbers of volumes, combine the command's arguments as
indicated:
=over 4
=item *
For every volume on a file server machine, specify the machine's name
with the B<-server> argument.
=item *
For every volume at a particular site, combine the -server
argument with the B<-partition> argument.
=back
To display the Volume Location Database (VLDB) entry for one or more
volumes, use the B<vos listvldb> command. To display both the
VLDB entry and the volume header for a single volume, use the B<vos
examine> command.
=head1 OPTIONS
=over 4
=item -server
Identifies the file server machine that houses volumes for which to
display the header. Provide the machine's IP address or its host
name (either fully qualified or using an unambiguous abbreviation). For
details, see the introductory reference page for the B<vos> command
suite.
This argument can be combined with the -partition argument, as
well as the B<-fast>, B<-long>, or B<-extended>
flag.
=item -partition
Identifies the partition (on the file server machine specified by the
B<-server> argument) that houses volumes for which to display the
header. Provide the partition's complete name with preceding slash
(for example, B</vicepa>) or use one of the three acceptable
abbreviated forms. For details, see the introductory reference page for
the B<vos> command suite.
=item -fast
Displays only the volume ID numbers of volumes stored at the site
specified by the B<-server>, and optionally B<-partition>,
argument. Do not combine this flag with the B<-extended>
flag.
=item -long
Displays more detailed information about each volume stored at the site
specified by the B<-server>, and optionally B<-partition>,
argument. The information includes the volume IDs of all three volume
types associated with the volume, and the read/write volume's quota,
creation date and update date.
=item -quiet
Suppresses the lines that summarize the number of volumes listed and their
status, which otherwise appear at the beginning and end of the output when the
output includes more than one volume.
=item -extended
Displays extensive statistics about access patterns for each volume stored
at the site specified by the B<-server>, and optionally
B<-partition>, argument. The statistics include the number of
reads and writes to files in the volume, and how recently files and
directories have been updated by their owners or other users. Do not
combine this flag with the B<-fast> flag.
=item -cell
Names the cell in which to run the command. Do not combine this
argument with the B<-localauth> flag. For more details, see the
introductory B<vos> reference page.
=item -noauth
Assigns the unprivileged identity anonymous to the
issuer. Do not combine this flag with the B<-localauth>
flag. For more details, see the introductory B<vos> reference
page.
=item -localauth
Constructs a server ticket using a key from the local
B</usr/afs/etc/KeyFile> file. The B<vos> command
interpreter presents it to the Volume Server and Volume Location Server during
mutual authentication. Do not combine this flag with the
B<-cell> argument or B<-noauth> flag. For more details,
see the introductory B<vos> reference page.
=item -verbose
Produces on the standard output stream a detailed trace of the
command's execution. If this argument is omitted, only warnings
and error messages appear.
=item -help
Prints the online help for this command. All other valid options
are ignored.
=back
=head1 OUTPUT
The output is ordered alphabetically by volume name and by default provides
the following information on a single line for each volume:
=over 4
=item *
Name
=item *
Volume ID number
L<(1)>
=item *
Type (the flag is C<RW> for read/write, C<RO> for
read-only, C<BK> for backup)
=item *
Size in kilobytes (C<1024> equals a megabyte)
=item *
Number of files in the volume, if the -extended flag is
provided
L<(1)>
=item *
Status on the file server machine, which is one of the following:
=over 4
=item C<On-line
>
The volume is completely accessible to Cache Managers.
L<(1)>
=item C<Off-line
>
The volume is not accessible to Cache Managers, but does not seem to be
corrupted. This status appears while a volume is being dumped, for
example.
L<(1)>
=item C<Off-line**needs salvage**
>
The volume is not accessible to Cache Managers, because it seems to be
corrupted. Use the B<bos salvage> or B<salvager>
command to repair the corruption.
=back
=back
If the following message appears instead of the previously listed
information, it indicates that a volume is not accessible to Cache Managers or
the B<vos> command interpreter, for example because a clone is being
created.
**** Volume I<volume_ID> is busy ****
If the following message appears instead of the previously listed
information, it indicates that the File Server is unable to attach the volume,
perhaps because it is seriously corrupted. The B<FileLog> and
B<VolserLog> log files in the B</usr/afs/logs> directory on
the file server machine possibly provide additional information; use the
B<bos getlog> command to display them.
**** Could not attach volume I<volume_ID> ****
The information about individual volumes is bracketed by summary
lines. The first line of output specifies the number of volumes in the
listing. The last line of output summarizes the number of volumes that
are online, offline, and busy. These lines do not appear if the
B<-quiet> flag is used.
If the -fast flag is added, the output displays only the volume
ID number of each volume, arranged in increasing numerical order. The
final line (which summarizes the number of online, offline, and busy volumes)
is omitted.
If the -long flag is included, the output for each volume
includes all of the information in the default listing plus the
following. Each item in this list corresponds to a separate line of
output:
=over 4
=item *
The file server machine and partition that house the volume, as determined
by the command interpreter as the command runs, rather than derived from the
VLDB or the volume header.
L<(1)>
L<(1)>
L<(1)>
L<(1)>
L<(1)>
L<(1)>
L<(1)>
L<(1)>
=item *
The volume ID numbers associated with the various versions of the
volume: read/write (C<RWrite>), read-only (C<ROnly>),
backup (C<Backup>), and ReleaseClone (C<RClone>). One
of them matches the volume ID number that appears on the first line of the
volume's output. If the value in the C<RWrite>,
C<ROnly>, or C<Backup> field is C<0> (zero), there is
no volume of that type. If there is currently no ReleaseClone, the
C<RClone> field does not appear at all.
L<(1)>
L<(1)>
=item *
The maximum space quota allotted to the read/write copy of the volume,
expressed in kilobyte blocks in the C<MaxQuota> field.
L<(1)>
L<(1)>
=item *
The date and time the volume was created, in the C<Creation>
field. If the volume has been restored with the B<backup
diskrestore>, B<backup volrestore>, or B<vos restore>
command, this is the restore time.
L<(1)>
L<(1)>
=item *
The date and time when the contents of the volume last changed, in the
C<Last Update> field. For read-only and backup volumes, it
matches the timestamp in the C<Creation> field.
L<(1)>
L<(1)>
=item *
The number of times the volume has been accessed for a fetch or store
operation since the later of the two following times:
=over 4
=item *
12:00 a.m. on the day the command is issued
=item *
The last time the volume changed location
=back
=back
If the -extended flag is included, the output for each volume
includes all of the information reported with the B<-long> flag, plus
two tables of statistics:
=over 4
=item *
The table labeled C<Raw Read/Write Stats> table summarizes the
number of times the volume has been accessed for reading or writing.
=item *
The table labeled C<Writes Affecting Authorship> table contains
information on writes made to files and directories in the specified
volume.
=back
