Figure 1.10, “ 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

/etc/init.d/httpd (specifying httpd).

A file system resource — Red Hat GFS named "gfs-content-webserver".
