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.
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.
vos changeloc takes the following options:
vos changeloc shows a brief message upon completion:
Changed location to server2 /vicepa for volume user.jdoe
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
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".
