DESCRIPTION
The vos move command moves the indicated read/write volume from its current site (specified with the
-fromserver and -frompartition arguments) to the destination site (specified with the -toserver and
-topartition arguments). This command automatically removes the backup copy from the current site, if it
exists. To create a new backup volume at the destination site, use the vos backup command.
This command works on read/write volumes only. To move a read-only volume, use the vos addsite and vos
release commands to define a new read-only site and release the volume contents to it, and then use the
vos remove command to remove the previous read-only volume's definition from the Volume Location Database
(VLDB) and data from the partition. To move a backup volume, use this command to move its read/write
source and then issue the vos backup command.
Before executing this command, the vos command interpreter initiates a check that the destination
partition contains enough space to house the volume being moved. If there is not enough space, the move
operation is not attempted and the following message appears:
vos: no space on target partition <dest_part> to move volume <volume>
CAUTIONS
Unless there is a compelling reason, do not interrupt a vos move command in progress. Interrupting a move
can result in one or more of the following inconsistent states:
• There are two versions of the volume, one at the source site and one at the destination site. (If
this happens, retain the version identified by the VLDB and use the vos zap command to remove the
other version.)
• The backup version of the volume is stranded at the old site. (If this happens, use the vos zap
command to remove it.)
• The volume is off-line. (If this happens, run the bos salvage command to bring it back on line.)
If the Ctrl-C interrupt signal is pressed while a vos move operation is executing, the following message
warns of the consequences and requests confirmation of the kill signal:
SIGINT handler: vos move operation in progress
WARNING: may leave AFS storage and metadata in indeterminate state
enter second control-c to exit
To confirm termination of the operation, press Ctrl-C a second time; press any other key to continue the
operation.
Currently, the maximum quota for a volume is 2 terabytes (2^41 bytes). Note that this only affects the
volume's quota; a volume may grow much larger if the volume quota is disabled. However, volumes over 2
terabytes in size may be impractical to move, and may have their size incorrectly reported by some tools,
such as fs_listquota(1).
OPTIONS
-id <volume name or ID>
Specifies either the complete name or volume ID number of a read/write volume.
-fromserver <server name>
Identifies the file server machine where the volume currently resides. Provide the machine's IP
address or its host name (either fully qualified or using an unambiguous abbreviation). For details,
see vos(1).
-frompartition <partition name>
Names the partition where the volume currently resides. Provide the full partition name (for,
example, /vicepa) or one of the abbreviated forms described in vos(1).
-toserver <server name>
Identifies the file server machine to which to move the volume. Provide the machine's IP address or
its host name (either fully qualified or using an unambiguous abbreviation). For details, see vos(1).
-topartition <partition name>
Names the partition to which to move the volume. Provide the full partition name (for, example,
/vicepa) or one of the abbreviated forms described in vos(1).
-live
Avoids making a temporary copy of the volume during the move. This is useful if the partition is
full, but the administrator needs to move volumes to a another partition or server to free up disk
space. The caveat is that the volume is locked during the entire operation instead of the short time
that is needed to make the temporary clone.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth 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).
-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).
-verbose
Produces on the standard output stream a detailed trace of the command's execution. If this argument
is omitted, only warnings and error messages appear.
-encrypt
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.
-noresolve
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.
-config <configuration directory>
Set the location of the configuration directory to be used. This defaults to /etc/openafs, except if
-localauth is specified, in which case the default is /etc/openafs/server. This option allows the use
of alternative configuration locations for testing purposes.
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following example moves the volume "user.smith" from the /vicepb partition on the file server machine
"fs3.example.com" to the /vicepg partition on the file server machine "fs7.example.com".
% vos move -id user.smith -fromserver fs3.example.com -frompartition b \
-toserver fs7.example.com -topartition g
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on the machines specified with the
-toserver and -fromserver arguments and on each database server machine. If the -localauth flag is
included, the issuer must instead be logged on to a server machine as the local superuser "root".
