vos_addsite - Adds a read-only site definition to a volume's VLDB entry

The vos addsite command defines a new read-only site (partition on a
file server machine, specified by the -server and -partition
arguments) in the Volume Location Database (VLDB) entry of the read/write
volume named by the -id argument. When the vos release command is
next issued against the read/write volume, a read-only copy of it is
distributed to all of the read-only sites, including the newly defined
A volume's VLDB entry accommodates a maximum number of site definitions,
as defined in the IBMAFS Release Notes. The site housing the
read/write and backup versions of the volume counts as one site, and each
read-only site counts as an additional site (even the read-only site
defined on the same file server machine and partition as the read/write
site counts as a separate site). The limit in the VLDB entry effectively
determines the maximum number of copies of the volume that are available
to AFS clients.
Attempts to create additional sites by using this command fail with an
-server <machine name>
Identifies the file server machine where the read-only volume is to
reside. Provide the machine's IP address or its host name (either fully
qualified or using an unambiguous abbreviation). For details, see
-partition <partition name>
Identifies the partition where the read-only volume is to reside, on the
file server machine named by the -server argument. Provide the
partition's complete name with preceding slash (for example, "/vicepa")
or use one of the three acceptable abbreviated forms. For details, see
-id <volume name or ID>
Specifies either the complete name or volume ID number of the read/write
-roid <readonly volume name or ID>
Specifies either the complete name or volume ID number of the readonly
volume. This will only be honored if the source read/write volume does not
already have a readonly volume ID associated with it. If the source
read/write volume already has a readonly volume ID, the specified ID will
be ignored, and a warning will be printed.
If this is not specified and the source read/write volume does not already
have a readonly volume ID, a volume ID for the readonly volume will be
allocated for it when the vos release command is run.
The automatically allocated readonly volume IDs should be fine for almost
all cases, so you should almost never need to specify this option.
Marks the site as up-to-date in the VLDB. You should only do this if the
new site already has a current readonly replica of the volume, but for
some reason it is not in the VLDB as a replica site. This is useful when
an existing read-only volume is dumped and restored with the -readonly
flag at the new site. This option is available in OpenAFS clients 1.4.7 or
later and 1.5.31 and later. This option can be used with OpenAFS server
versions later than 1.4.1 or 1.5.0.
-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).
Assigns the unprivileged identity anonymous to the issuer. Do not combine
this flag with the -localauth flag. For more details, see vos(1).
Constructs a server ticket using a key from the local
/etc/openafs/server/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).
Produces on the standard output stream a detailed trace of the command's
execution. If this argument is omitted, only warnings and error messages
Prints the online help for this command. All other valid options are
The following example, appropriate in the State University cell, defines a
read-only site for the cell's "root.afs" volume.
% vos addsite -server sv7.stateu.edu -partition /vicepb -id root.afs
The issuer must be listed in the /etc/openafs/server/UserList file on the
machine specified with the -server argument and 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".
