NAME

       vos_move - Moves a read/write volume to another site

SYNOPSIS

       vos move -id <volume name or ID>
           -fromserver <machine name on source>
           -frompartition <partition name on source>
           -toserver <machine name on destination>
           -topartition <partition name on destination>
           [-live] [-cell <cell name>] [-noauth]
           [-localauth] [-verbose] [-help]

       vos m -i <volume name or ID>
           -froms <machine name on source>
           -fromp <partition name on source>
           -tos <machine name on destination>
           -top <partition name on destination> [-li]
           [-c <cell name>] [-n] [-l] [-v] [-h]

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 size of a volume is 2 terabytes (2^31 bytes) and
       the maximum size of a /vicepX partition on a fileserver is also 2
       terabytes. The fileserver will not report an error when it has access
       to a partition larger than 2 terabytes, but it will probably fail if
       the administrator attempts to use more than 2 terabytes of space. In
       addition, there are reports of erroneous disk usage numbers when vos
       partinfo or other OpenAFS disk reporting tools are used with partitions
       larger than 2 terabytes.

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.

       -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.abc.com" to the /vicepg
       partition on the file server machine "fs7.abc.com".

          % vos move -id user.smith -fromserver fs3.abc.com -frompartition b \
              -toserver fs7.abc.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".
