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".
