NAME
ccs - Cluster Configuration System
DESCRIPTION
- A cluster environment that shares resources has informa
- tion that is essential to correct operation which must be avail
- able 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.
OVERVIEW
- The following is a generic description of the steps one
- should take to produce a working CCS environment.
- Step 1
- 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.
- Step 2
- Create the directory /etc/cluster.
- Step 3
- Create the /etc/cluster/cluster.conf file, according to
- the cluster.conf(5) man page, on one node in your cluster.
- Step 4
- 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/clus
- ter/cluster.conf".
