=head1 DESCRIPTION The B command moves the indicated read/write volume from its current site (specified with the B<-fromserver> and B<-frompartition> arguments) to the destination site (specified with the B<-toserver> and B<-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 B command. This command works on read/write volumes only. To move a read-only volume, use the B and B commands to define a new read-only site and release the volume contents to it, and then use the B 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 B command. Before executing this command, the B 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 to move volume =head1 CAUTIONS Unless there is a compelling reason, do not interrupt a B command in progress. Interrupting a move can result in one or more of the following inconsistent states: =over 4 =item * 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 B command to remove the other version.) =item * The backup version of the volume is stranded at the old site. (If this happens, use the B command to remove it.) =item * The volume is off-line. (If this happens, run the B command to bring it back on line.) =back 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). =head1 OPTIONS =over 4 =item B<-id> > Specifies either the complete name or volume ID number of a read/write volume. =item B<-fromserver> > 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 L. =item B<-frompartition> > Names the partition where the volume currently resides. Provide the full partition name (for, example, B) or one of the abbreviated forms described in L. =item B<-toserver> > 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 L. =item B<-topartition> > Names the partition to which to move the volume. Provide the full partition name (for, example, B) or one of the abbreviated forms described in L. =item B<-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. =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 EXAMPLES The following example moves the volume C from the F partition on the file server machine C to the F partition on the file server machine C. % vos move -id user.smith -fromserver fs3.abc.com -frompartition b \ -toserver fs7.abc.com -topartition g =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on the machines specified with the B<-toserver> and B<-fromserver> arguments and 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, L, L, L =head1 COPYRIGHT IBM Corporation 2000.
