NAME
cluster.conf - configuration file for cman, fence, dlm, gfs, rgmanager
DESCRIPTION
The
cluster.conf file is located in the /etc/cluster directory. It
is the source of information used by cman, fence, dlm, gfs and rgmanager.
It's accessed indirectly through libccs (see
ccs(7)). This file
contains all the information needed for the cluster to operate, such as
what nodes are in the cluster and how to I/O fence those nodes.
This man page describes the generic contents of the
cluster.conf
file. For other information see man pages for cman(5), fenced(8) and
dlm_controld(8).
cluster.conf is an XML file. It has one top-level
cluster
section containing everything else. The cluster section has two mandatory
attributes:
name and
config_version.
name can be up to
16 characters long and specifies the name of the cluster. It is important
that this name is unique from other clusters the user might set up.
config_version is a number used to identify the revision level of
the
cluster.conf file. Given this information, your
cluster.conf file might look something like:
<cluster name="alpha" config_version="1">
</cluster>
Nodes
The set of nodes that make up the cluster are defined under the
clusternodes section. A
clusternode section defines each
node. A clusternode has two mandatory attributes:
name
and
nodeid
The name should correspond to the hostname (the fully qualified name is
generally not necessary) on the network interface to be used for cluster
communication. Nodeid's must be greater than zero and unique.
<cluster name="alpha" config_version="1">
<clusternodes>
<clusternode name="node-01" nodeid="1">
</clusternode>
<clusternode name="node-02" nodeid="2">
</clusternode>
<clusternode name="node-03" nodeid="3">
</clusternode>
</clusternodes>
</cluster>
The next step in completing cluster.conf is adding fencing information;
see fenced(8).
