ccs - Cluster Configuration System
A cluster environment that shares resources has information that is
essential to correct operation which must be available to
every node in the cluster. This information may include:
names of the nodes composing the cluster, I/O fencing methods, and
more. CCS is the system that makes it possible for the nodes in a
cluster to retrieve the information they need.
The following is a generic description of the steps one should take to produce
a working CCS environment.
Choose a cluster name. It is important to determine
a name for the cluster before starting. The cluster name is what
binds a machine to specific resources that can only be shared by
machines that are members of the same cluster name.
Create the directory /etc/cluster.
Create the /etc/cluster/cluster.conf file, according to the
cluster.conf(5) man page, on one node in your cluster.
Start ccsd and test the cluster.conf file by using ccs_test.
If you haven't started a cluster manager yet, you should use the 'force'
option to ccs_test - see the ccs_test(8) man page for more info.
If a failure occurs while parsing the config file, ccs_test should
report "ccs_connect failed: No data available" and /var/log/messages
should report "Unable to parse /etc/cluster/cluster.conf".
