=head1 DESCRIPTION The B 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 B, run B and then B against the new server to ensure full synchronization of the VLDB with the file server. In essence, B performs the same operations on the VLDB as B, but it does NOT move the data from one server's file system to another. =head1 CAUTIONS Using B 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, B should be used instead. It is highly recommended that B and B be run after using the B command to ensure properly synchronization of the VLDB with the file servers. =head1 OPTIONS B takes the following options: =over 4 =item B<-server> > 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 L. =item B<-partition> > Specifies the partition where the VLDB should believe the volume resides. entries. Provide the B<-server> argument along with this one. Provide the partition's complete name with preceding slash (for example, C) or use one of the three acceptable abbreviated forms. For details, see L. =item B<-id> > Specifies the name or volume ID number on which to operate. =item B<-cell> > Names the cell in which to run the command. Do not combine this argument with the B<-localauth> flag. For more details, see L. =item B<-noauth> Assigns the unprivileged identity C to the issuer. Do not combine this flag with the B<-localauth> flag. For more details, see L. =item B<-localauth> Constructs a server ticket using a key from the local F file. The B command interpreter presents it to the Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the B<-cell> argument or B<-noauth> flag. For more details, see L. =item B<-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. =item B<-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. =item B<-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. =item B<-help> Prints the online help for this command. All other valid options are ignored. =back =head1 OUTPUT B shows a brief message upon completion: Changed location to server2 /vicepa for volume user.jdoe =head1 EXAMPLES The following command changes the location of the C volume to be F on the file server machine C 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 C volume to be F on C without being verbose: % vos changeloc server1 a user.jdoe Changed location to server1 /vicepa for volume user.jdoe =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on each database server machine. If the B<-localauth> flag is included, the issuer must instead be logged on to a server machine as the local superuser C. =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT Copyright 2007 Jason Edgecombe This documentation is covered by the BSD License as written in the doc/LICENSE file.
