NAME
vos_size - Computes the size of a volume dump
SYNOPSIS
vos size [-cell <cell name>] [-dump]
[-encrypt] [-help] [-id] <volume name or id>
[-localauth] [-noauth]
[-partition <partition name>]
[-server <machine name>]
[-time <dump from time>] [-verbose]
DESCRIPTION
The 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 vos examine or 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).
OPTIONS
-cell <cell name>
The cell in which the volume resides, if it’s not in the current
cell.
-dump
Show the size of the volume dump for the specified volume.
Currently, this flag should always be given for vos size to give
useful information. It is present to allow this command to provide
other size estimates in the future.
-encrypt
Encrypt the command.
-help
Prints the online help for this command. All other valid options
are ignored.
-id <volume name or id>
Specifies either the complete name or volume ID number of the
read/write, read-only, or backup volume to size.
-localauth
Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The vos command interpreter
presents it to the Volume Server and Volume Location Server during
mutual authentication. Do not combine this flag with the -cell
argument or -noauth flag. For more details, see vos(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
vos(1).
-partition <partition name>
Specifies the partition on which the volume resides. Provide the
-server argument along with this one.
-server <machine name>
Specifies the file server machine on which the volume resides.
Provide the -partition argument along with this one.
-time <dump from time>
Specifies whether the dump is full or incremental. Omit this
argument to size a full dump. See vos_dump(1) for the valid values
for this option.
-verbose
Show more output about what’s going on.
OUTPUT
When run without -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 -verbose, additional status messages will be
printed between those two lines.
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
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on
the machine specified with the -server argument or the machine on which
the volume is located if -server was not given. If the -localauth flag
is included, the issuer must instead be logged on to a server machine
as the local superuser "root".
