NAME

       vos_changeloc - Change a volume's entry in the VLDB

SYNOPSIS

       vos changeloc [-server] <new server name>
          [-partition] <new partition location>
          [-id] <volume name or ID>
          [-cell <cell name>] [-noauth] [-localauth]
          [-verbose] [-encrypt] [-noresolve] [-help]

       vos changel [-s] <new server name>
          [-p] <new partition location>
          [-i] <volume name or ID>
          [-c <cell name>]
          [-noa] [-l] [-v] [-e] [-nor] [-h]

DESCRIPTION

       The vos changeloc command changes the location of a volume in the Volume Location Database
       (VLDB) without needing to contact the original file server on which the volume was hosted.
       This is useful when a file server has gone down permanently and the data that was stored
       on that server has been moved to a new file server with a different name and IP address
       (perhaps by mounting the same /vicepX partitions on a different host). After moving the
       data and running vos changeloc, run vos syncvldb and then vos syncserv against the new
       server to ensure full synchronization of the VLDB with the file server.

       In essence, vos changeloc performs the same operations on the VLDB as vos move, but it
       does NOT move the data from one server's file system to another.

CAUTIONS

       Using vos changeloc changes the VLDB without modifying the file server data, so it
       inherently causes the VLDB to be out of sync with the data on the servers. It should only
       be used when recovering from server failure.  If the servers are on-line, vos move should
       be used instead. It is highly recommended that vos syncvldb and vos syncserv be run after
       using the vos changeloc command to ensure properly synchronization of the VLDB with the
       file servers.

OPTIONS

       vos changeloc takes the following options:

       -server <new server name>
           Specifies the new server where the VLDB should believe the volume resides.  Provide
           the machine's IP address or its host name (either fully qualified or using an
           unambiguous abbreviation). For details, see vos(1).

       -partition <partition name>
           Specifies the partition where the VLDB should believe the volume resides.  Provide the
           -server argument along with this one. Provide the partition's complete name with
           preceding slash (for example, "/vicepa") or use one of the three acceptable
           abbreviated forms. For details, see vos(1).

       -id <volume name or ID>
           Specifies the name or volume ID number on which to operate.

       -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.

       -help
           Prints the online help for this command. All other valid options are ignored.

OUTPUT

       vos changeloc shows a brief message upon completion:

          Changed location to server2 /vicepa for volume user.jdoe

EXAMPLES

       The following command changes the location of the "user.jdoe" volume to be /vicepa on the
       file server machine "server2" while being verbose:

          % vos changeloc server2 a user.jdoe -verbose
           done
          Changed location to server2 /vicepa for volume user.jdoe

       The following command changes the location of the "user.jdoe" volume to be /vicepa on
       "server1" without being verbose:

          % vos changeloc server1 a user.jdoe
          Changed location to server1 /vicepa for volume user.jdoe

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file 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".
