DESCRIPTION
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 one.
CAUTIONS
A volume's VLDB entry accommodates a maximum number of 16 site
definitions. The site housing the read/write and backup versions of the
volume counts as one site, the backup snapshot counts as one site, and
one site should be reserved for a transient clone for volume moves and
similar operations. 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
error.
OPTIONS-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 vos(1).
-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 vos(1).
-id <volume name or ID>
Specifies either the complete name or volume ID number of the
read/write source volume.
-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 them
explicitly. This option is available in OpenAFS versions 1.5.61 or
later.
-valid
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 or 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).
-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.
EXAMPLES
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
PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/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".
