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.
