Fig u re 1.10. Web Server C lu st er Service Example
Clients access the cluster service through the IP address 10.10.10.201, enabling interaction with the
web server application, httpd-content. The httpd-content application uses the gfs-content-webserver
file system. If node B were to fail, the content-webserver cluster service would fail over to node D. If
node D were not available or also failed, the service would fail over to node A. Failover would occur
with no apparent interruption to the cluster clients. The cluster service would be accessible from
another cluster node via the same IP address as it was before failover.
