VOS_CHANGELOC(1) AFS Command Reference VOS_CHANGELOC(1)NAMEvos_changeloc - Change a volume's entry in the VLDB
SYNOPSIS
vos changeloc [-server] <new server name>
[-partition] <new partition location>
[-id] <volume name or ID>
[-cell <cell name>] [-noauth] [-localauth]
[-verbose] [-encrypt] [-noresolve] [-help]
vos changel [-s] <new server name>
[-p] <new partition location>
[-i] <volume name or ID>
[-c <cell name>]
[-noa] [-l] [-v] [-e] [-nor] [-h]
DESCRIPTION
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.
CAUTIONS
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.
OPTIONS
vos changeloc takes the following options:
-server <new server name>
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 vos(1).
-partition <partition name>
Specifies the partition where the VLDB should believe the volume
resides. Provide the -server argument along with this one. Provide
the partition's complete name with preceding slash (for example,
"/vicepa") or use one of the three acceptable abbreviated forms.
For details, see vos(1).
-id <volume name or ID>
Specifies the name or volume ID number on which to operate.
-cell <cell name>
Names the cell in which to run the command. Do not combine this
argument with the -localauth flag. For more details, see vos(1).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
vos(1).
-localauth
Constructs a server ticket using a key from the local
/usr/afs/etc/KeyFile file. The vos command interpreter presents it
to the Volume Server and Volume Location Server during mutual
authentication. Do not combine this flag with the -cell argument or
-noauth flag. For more details, see vos(1).
-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.
-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.
-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.
-help
Prints the online help for this command. All other valid options
are ignored.
OUTPUT
vos changeloc shows a brief message upon completion:
Changed location to server2 /vicepa for volume user.jdoe
EXAMPLES
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
PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/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".
