Add new man pages for livesys and voldump. Fix the man page for sys to say what it actually does, rather than implying that it works like livesys, and to recommend livesys instead. Fix a path error in the NetInfo documentation. Update the README for the current status, including listing all installed commands that don't have man pages. (There may still be some subcommands that don't have man pages but aren't listed.)

voldump - Dump an AFS volume without using the Volume Server
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<voldump> B<-part> <I<partition>> B<-volumeid> <I<volume id>>
|
|
[B<-file> <I<dump file>>] [B<-verbose>] [B<-help>]
|
|
|
|
B<voldump> B<-p> <I<partition>> B<-vo> <I<volume id>>
|
|
[B<-f> <I<dump file>>] [B<-ve>] [B<-h>]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<voldump> dumps an AFS volume in the format used by B<vos dump> without
|
|
using the Volume Server. It must be run on the file server machine and
|
|
usually must be run as the superuser C<root> to have permissions to read
|
|
the file server data. It's primary use is to recover data from a file
|
|
server machine where the Volume Server cannot be started for some reason.
|
|
|
|
The dump output will go to standard output, or to a file if B<-file> is
|
|
specified. B<vos restore> can be used to load the resulting dump into a
|
|
new AFS volume. B<voldump> always does a full dump.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
Normally, use B<vos dump> instead of this command. B<voldump> is a tool
|
|
of last resort to try to extract data from the raw data structures stored
|
|
on the file server machine and is not as regularly tested or used as the
|
|
normal B<vos dump> implementation.
|
|
|
|
If the AFS volume being dumped changes while B<voldump> is running, the
|
|
results may be inconsistent. If the File Server and Volume Server are
|
|
running, stop them with B<bos shutdown> or a similar method before running
|
|
this command.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-part> <I<partition>>
|
|
|
|
Names the partition on which the volume to be dumped is located.
|
|
B<voldump> does not take the normal full range of ways of specifying a
|
|
partition. Instead, I<partition> must be either a single letter between
|
|
C<a> and C<z>, corresponding to F</vicepa> through F</vicepz>, or the full
|
|
path to the file server partition. C<aa> is not recognized; use
|
|
F</vicepaa> instead.
|
|
|
|
=item B<-volumeid> <I<volume id>>
|
|
|
|
Specifies the ID of the volume to dump. The volume must be specified by
|
|
numeric ID, not by name.
|
|
|
|
=item B<-file> <I<dump file>>
|
|
|
|
Specifies the output file for the dump. If this option is not given, the
|
|
volume will be dumped to standard output.
|
|
|
|
=item B<-verbose>
|
|
|
|
Asks for a verbose trace of the dump process. This trace information will
|
|
be sent to standard error.

=head1 EXAMPLES
|
|
|
|
The following command dumps the volume 1936964939 on the F</vicepb>
|
|
partition to the file F</tmp/volume.dump>:
|
|
|
|
% voldump -part /vicepb -volumeid 1936964939 -file /tmp/volume.dump
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
The issuer must have read access to the file server data stored in the
|
|
specified partition. Usually, this means that the issuer must be the
|
|
local superuser C<root> on the file server machine.
