<BR>
You cannot currently use these services and virtual servers in the same setup, if you do, any configuration you had for virtual servers will be lost.<BR>
You must have at least a 2 node cluster (a primary and backup) in order to use these failover services.<BR>
All nodes must be identically configured Linux systems.
<P>
Failover services provide the most basic form of fault recovery. If any of the services on the active node fail, all of the services will be
shutdown and restarted on a backup node. Services defined here will automatically be started & stopped by LVS, so a backup node is
considered a "warm" standby. This is due to a technical restriction that a service can only be operational on one node at a time, otherwise it may
fail to bind to a virtual IP address that does not yet exist on that system or cause a networking conflict with the active service. The
commands provided for "Initiation command" and "Stop command" must work the same for all nodes. Multiple services can be defined.
