=head1 DESCRIPTION
|
|
|
|
The B<vos size> command shows the size of a volume's dump for backup
|
|
purposes. The size of the dump may differ from the volume size as reported
|
|
by B<vos examine> or B<fs listquota>. The size is shown in bytes.
|
|
|
|
This command is intended for use with backup systems that want to size
|
|
volume dumps before performing them (to optimize use of tape resources,
|
|
for example).
|
|
|
|
=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. Currently, this
|
|
flag should always be given for B<vos size> to give useful information.
|
|
It is present to allow this command to provide other size estimates in the
|
|
future.
|
|
|
|
=item B<-encrypt>
|
|
|
|
Encrypt the command.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.
|
|
|
|
=item B<-id> <I<volume name or id>>
|
|
|
|
Specifies either the complete name or volume ID number of the read/write,
|
|
read-only, or backup volume to size.
|
|
|
|
=item B<-localauth>
|
|
|
|
Constructs a server ticket using a key from the local
|
|
F</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 L<vos(1)>.
|
|
|
|
=item B<-noauth>
|
|
|
|
Assigns the unprivileged identity anonymous to the issuer. Do not combine
|
|
this flag with the B<-localauth> flag. For more details, see L<vos(1)>.
|
|
|
|
=item B<-partition> <I<partition name>>
|
|
|
|
Specifies the partition on which the volume resides. Provide the
|
|
B<-server> argument along with this one.
|
|
|
|
=item B<-server> <I<machine name>>
|
|
|
|
Specifies the file server machine on which the volume resides. Provide
|
|
the B<-partition> argument along with this one.
|
|
|
|
=item B<-time> <I<dump from time>>
|
|
|
|
Specifies whether the dump is full or incremental. Omit this argument to
|
|
size a full dump. See L<vos_dump(1)> for the valid values for this
|
|
option.
|
|
|
|
=item B<-verbose>
|
|
|
|
Show more output about what's going on.
|
|
|
|
=back
|
|
|
|
=head1 OUTPUT
|
|
|
|
When run without B<-verbose>, the output will be:
|
|
|
|
Volume: <volume>
|
|
dump_size: <size>
|
|
|
|
where <volume> is the name of the volume and <size> is the size of the
|
|
dump in bytes. With B<-verbose>, additional status messages will be
|
|
printed between those two lines.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
Sizing a single user volume:
|
|
|
|
% vos size user.thoron -dump
|
|
Volume: user.thoron
|
|
dump_size: 36430
|
|
|
|
or, more verbosely:
|
|
|
|
% vos size user.thoron -dump -verbose
|
|
Volume: user.thoron
|
|
Starting transaction on volume 2003434023... done
|
|
Getting size of volume on volume 2003434023... done
|
|
Ending transaction on volume 2003434023... done
|
|
dump_size: 36430
|
|
|
|
Sizing an incremental dump for the same volume:
|
|
|
|
% vos size -id user.thoron -time '05/04/2007 00:00:00' -dump
|
|
Volume: user.thoron
|
|
dump_size: 21095
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
The issuer must be listed in the F</usr/afs/etc/UserList> file on the
|
|
machine specified with the B<-server> argument or the machine on which the
|
|
volume is located if B<-server> was not given. If the B<-localauth> flag
|
|
is included, the issuer must instead be logged on to a server machine as
|
|
the local superuser C<root>.
