Chapter 1. Red Hat Cluster Suite Overview
Figure 1.10. Failover Domains
Figure 1.11, "Web Server Cluster Service Example" shows an example of a high-availability
cluster service that is a web server named "content-webserver". It is running in cluster node B
and is in a failover domain that consists of nodes A, B, and D. In addition, the failover domain is
configured with a failover priority to fail over to node D before node A and to restrict failover to
nodes only in that failover domain. The cluster service comprises these cluster resources:
• IP address resource — IP address 10.10.10.201.
• An application resource named "httpd-content" — a web server application init script
(specifying ).
/etc/init.d/httpd httpd
• A file system resource — Red Hat GFS named "gfs-content-webserver".
