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
backup addvolentry - Defines a volume entry in a volume set
=head1 SYNOPSIS
B<backup addvolentry -name> <I<volume set name>> -server <I<machine name>>
B<-partition> <I<partition name>>
-volumes <I<volume name (regular expression)>>
[B<-localauth>] [B<-cell> <I<cell name>>] [-help]
B<backup addvole -n> <I<volume set name>> B<-s> <I<machine name>> -p <I<partition name>>
B<-v> <I<volume name (regular expression)>>
[B<-l>] [B<-c> <I<cell name>>] [-h]
=head1 DESCRIPTION
The backup addvolentry command adds a volume entry definition to
the existing volume set named by the B<-name> argument. A
volume entry definition can match one or more volumes, depending on the
combination of the B<-server>, B<-partition>, and
B<-volumes> arguments.
For the B<-server> and -partition arguments, provide
either
=over 4
=item *
The name of one machine or partition
=item *
The metacharacter expression .* (period and asterisk),
which matches every machine name or partition name in the Volume Location
Database (VLDB).
=back
For the -volumes argument, specify a combination of alphanumeric
characters and one or more metacharacters to wildcard part or all of the
volume name. The B<Options> section lists the acceptable
metacharacters.
=head1 CAVEATS
It is best to issue this command in interactive mode. If issuing it
at the shell prompt, enclose any strings containing metacharacters in double
quotes, or escape the metacharacters with other delimiters, to prevent the
shell from interpreting them. Adding volume entries to a temporary
volume set is possible only within the interactive session in which the volume
set was created.
=head1 OPTIONS
=over 4
=item -name
Names the volume set to which to add this volume entry definition.
The volume set must already exist (use the B<backup addvolset> command
to create it).
=item -server
Defines the set of one or more file server machines that house the volumes
in the volume entry. Provide either one fully-qualified hostname (such
as B<fs1.abc.com>) or the metacharacter expression
B<.*> (period and asterisk), which matches all machine names in
the VLDB.
=item -partition
Defines the set of one or more partitions that house the volumes in the
volume entry. Provide either one complete partition name (such as
B</vicepa>) or the metacharacter expression B<.*>
(period and asterisk), which matches all partition names.
=item -volumes
Defines the set of one or more volumes included in the volume
entry. Specify the volumes by name, by using any combination of regular
alphanumeric characters and one or more of the following metacharacter
expressions:
L<(1)>
L<(1)>
=over 4
=item .
The period matches any single character.
=item *
The asterisk matches zero or more instances of the preceding
character. Combine it with any other alphanumeric character or
metacharacter.
=item [ ]
Square brackets around a list of characters match a single instance of any
of the characters, but no other characters; for example, B<[abc]>
matches a single B<a> or B<b> or B<c>, but not
B<d> or B<A>. This expression can be combined with the
asterisk.
=item ^
The caret, when used as the first character in a square-bracketed set,
designates a match with any single character I<except> the characters
that follow it; for example, B<[^a]> matches any single character
except lowercase B<a>. This expression can be combined with the
asterisk.
=item \
A backslash preceding any of the metacharacters in this list makes it
match its literal value only. For example, the expression
B<\.> (backslash and period) matches a single period,
B<\*> a single asterisk, and B<\\> a single backslash.
Such expressions can be combined with the asterisk (for example,
B<\.*> matches any number of periods).
=back
Perhaps the most common metacharacter expression is the period followed by
an asterisk (B<.*>). This expression matches any string
of any length, because the period matches any character and the asterisk means
any number of that character. As mentioned, it is the only acceptable
metacharacter expression for the B<-server> and B<-partition>
arguments. In a volume definition it can stand alone (in which case it
matches every volume listed in the VLDB), or can combine with regular
characters. The following example matches any volume name that begins
with the string B<user> and ends with B<backup>:
user.*backup
=item -localauth
Constructs a server ticket using a key from the local
B</usr/afs/etc/KeyFile> file. The B<backup> command
interpreter presents it to the Backup Server, Volume Server and VL Server
during mutual authentication. Do not combine this flag with the
B<-cell> argument. For more details, see the introductory
B<backup> reference page.
=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<backup> reference page.
=item -help
Prints the online help for this command. All other valid options
are ignored.
=back
=head1 EXAMPLES
The following command adds a volume entry to the volume set called
B<sys>. The entry matches all volumes on any machine or
partition whose names begin with the string B<sun4x_56> followed by a
period:
backup> addvolentry sys .* .* sun4x_56\..*
The following command adds a volume entry to the volume set called
B<fs2>, to match all volumes on the B</vicepb> partition of
file server machine B<fs2.abc.com>. Because it is
issued at the shell prompt, double quotes surround the metacharacters in the
B<-volumes> argument. (The command is shown here on two lines
only for legibility reasons.)
% backup addvolentry -name fs2 -server fs2.abc.com \
-partition /vicepb -volumes ".*"
The chapter in the I<IBM AFS Administration Guide> about
configuring the AFS Backup System presents additional examples as well as
advice on grouping volumes.
=head1 PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/UserList file on
every machine where the Backup Server is running, or must be logged onto a
server machine as the local superuser B<root> if the
B<-localauth> flag is included.
