VOS_SIZE(1) AFS Command Reference VOS_SIZE(1)
vos_size - Computes the size of a volume dump
vos size [-id] <volume name or id>
[-partition <partition name>]
[-server <machine name>]
[-dump] [-time <dump from time>]
[-cell <cell name>]
[-verbose] [-encrypt] [-noresolve] [-help]
vos si [-i] <volume name or id>
[-p <partition name>]
[-s <machine name>]
[-d] [-t <dump from time>]
[-c <cell name>]
[-v] [-e] [-nor] [-h]
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).
-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.
-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.
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.
-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
-cell <cell name>
The cell in which the volume resides, if it's not in the current cell.
Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see
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).
Show more output about what's going on.
Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in
OpenAFS versions 1.4.11 or later and 1.5.60 or later.
Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or
when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.
Prints the online help for this command. All other valid options are ignored.
When run without -verbose, the output will be:
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.
Sizing a single user volume:
% vos size user.thoron -dump
or, more verbosely:
% vos size user.thoron -dump -verbose
Starting transaction on volume 2003434023... done
Getting size of volume on volume 2003434023... done
Ending transaction on volume 2003434023... done
Sizing an incremental dump for the same volume:
% vos size -id user.thoron -time '05/04/2007 00:00:00' -dump
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".
