High-availability Service Management
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 /etc/
init.d/httpd (specifying httpd).
• A file system resource — Red Hat GFS named "gfs-content-webserver".
