=head1 NAME vos move - Moves a read/write volume to another site =head1 SYNOPSIS B > -fromserver > B<-frompartition> > -toserver > -topartition > [B<-cell> >] [B<-noauth>] [B<-localauth>] [B<-verbose>] [-help] B > -froms > B<-fromp> > B<-tos> > B<-top> > [-c >] [B<-n>] [B<-l>] [B<-v>] [-h] =head1 DESCRIPTION The vos move 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 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 I to move volume I =head1 CAVEATS 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: =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 bos salvage command to bring it back on line.) =back If the > 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 a second time; press any other key to continue the operation. =head1 OPTIONS =over 4 =item -id Specifies either the complete name or volume ID number of a read/write volume. =item -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 the introductory reference page for the B command suite. =item -frompartition Names the partition where the volume currently resides. Provide the full partition name (for, example, B) or one of the abbreviated forms described on the introductory B reference page. =item -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 the introductory reference page for the B command suite. =item -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 on the introductory B reference page. =item -cell Names the cell in which to run the command. Do not combine this argument with the B<-localauth> flag. For more details, see the introductory B reference page. =item -noauth Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the B<-localauth> flag. For more details, see the introductory B reference page. =item -localauth Constructs a server ticket using a key from the local B 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 the introductory B reference page. =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. =item -help Prints the online help for this command. All other valid options are ignored. =back =head1 EXAMPLES The following example moves the volume user.smith from the B partition on the file server machine B to the B partition on the file server machine B. % 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 /usr/afs/etc/UserList 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 B. =head1 SEE ALSO L, L, L, L, L, L =head1 COPYRIGHT IBM Corporation 2000.
