NAME
vos_addsite - Adds a read-only site definition to a volume’s VLDB entry
SYNOPSIS
vos addsite -server <machine name for new site>
-partition <partition name for new site>
-id <volume name or ID>
[-roid <readonly volume name or ID>]
[-valid] [-cell <cell name>]
[-noauth] [-localauth]
[-verbose] [-help]
vos ad -s <machine name for new site>
-p <partition name for new site>
-i <volume name or ID>
[-r <readonly volume name or ID>]
[-va] [-c <cell name>] >>> [-n] [-l] [-v] [-h]
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 site
definitions, as defined in the IBM AFS 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
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 this
option.
-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 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).
-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
/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).
-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.
-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 /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".
