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 \fBvos changeloc\fR, run \fBvos syncvldb\fR and then \fBvos syncserv\fR against the new server to ensure full synchronization of the VLDB with the file server. .PP In essence, \fBvos changeloc\fR performs the same operations on the VLDB as \&\fBvos move\fR, but it does NOT move the data from one server's file system to another. .SH CAUTIONS .IX Header "CAUTIONS" Using \fBvos changeloc\fR 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, \fBvos move\fR should be used instead. It is highly recommended that \fBvos syncvldb\fR and \fBvos syncserv\fR be run after using the \fBvos changeloc\fR command to ensure properly synchronization of the VLDB with the file servers. .SH OPTIONS .IX Header "OPTIONS" \&\fBvos changeloc\fR takes the following options: .IP "\fB\-server\fR <\fInew server name\fR>" 4 .IX Item "-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 \fBvos\fR\|(1). .IP "\fB\-partition\fR <\fIpartition name\fR>" 4 .IX Item "-partition " Specifies the partition where the VLDB should believe the volume resides. Provide the \fB\-server\fR argument along with this one. Provide the partition's complete name with preceding slash (for example, \f(CW\*(C`/vicepa\*(C'\fR) or use one of the three acceptable abbreviated forms. For details, see \&\fBvos\fR\|(1). .IP "\fB\-id\fR <\fIvolume name or ID\fR>" 4 .IX Item "-id " Specifies the name or volume ID number on which to operate. .IP "\fB\-cell\fR <\fIcell name\fR>" 4 .IX Item "-cell " Names the cell in which to run the command. Do not combine this argument with the \fB\-localauth\fR flag. For more details, see \fBvos\fR\|(1). .IP \fB\-noauth\fR 4 .IX Item "-noauth" Assigns the unprivileged identity \f(CW\*(C`anonymous\*(C'\fR to the issuer. Do not combine this flag with the \fB\-localauth\fR flag. For more details, see \&\fBvos\fR\|(1). .IP \fB\-localauth\fR 4 .IX Item "-localauth" Constructs a server ticket using a key from the local \&\fI/etc/openafs/server/KeyFile\fR file. The \fBvos\fR command interpreter presents it to the Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the \fB\-cell\fR argument or \&\fB\-noauth\fR flag. For more details, see \fBvos\fR\|(1). .IP \fB\-verbose\fR 4 .IX Item "-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. .IP \fB\-encrypt\fR 4 .IX Item "-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. .IP \fB\-noresolve\fR 4 .IX Item "-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. .IP "\fB\-config\fR <\fIconfiguration directory\fR>" 4 .IX Item "-config " Set the location of the configuration directory to be used. This defaults to \&\fI/etc/openafs\fR, except if \fB\-localauth\fR is specified, in which case the default is \fI/etc/openafs/server\fR. This option allows the use of alternative configuration locations for testing purposes. .IP \fB\-help\fR 4 .IX Item "-help" Prints the online help for this command. All other valid options are ignored. .SH OUTPUT .IX Header "OUTPUT" \&\fBvos changeloc\fR shows a brief message upon completion: .PP .Vb 1 \& Changed location to server2 /vicepa for volume user.jdoe .Ve .SH EXAMPLES .IX Header "EXAMPLES" The following command changes the location of the \f(CW\*(C`user.jdoe\*(C'\fR volume to be \fI/vicepa\fR on the file server machine \f(CW\*(C`server2\*(C'\fR while being verbose: .PP .Vb 3 \& % vos changeloc server2 a user.jdoe \-verbose \& done \& Changed location to server2 /vicepa for volume user.jdoe .Ve .PP The following command changes the location of the \f(CW\*(C`user.jdoe\*(C'\fR volume to be \fI/vicepa\fR on \f(CW\*(C`server1\*(C'\fR without being verbose: .PP .Vb 2 \& % vos changeloc server1 a user.jdoe \& Changed location to server1 /vicepa for volume user.jdoe .Ve .SH "PRIVILEGE REQUIRED" .IX Header "PRIVILEGE REQUIRED" The issuer must be listed in the \fI/etc/openafs/server/UserList\fR file on each database server machine. If the \fB\-localauth\fR flag is included, the issuer must instead be logged on to a server machine as the local superuser \&\f(CW\*(C`root\*(C'\fR. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBvos\fR\|(1), \&\fBvos_move\fR\|(1), \&\fBvos_syncserv\fR\|(1), \&\fBvos_syncvldb\fR\|(1) .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2007 Jason Edgecombe .PP This documentation is covered by the BSD License as written in the doc/LICENSE file.
