Hello.
I encountered the following problem:
I wanted to test how clusterIP works. So on 2 test machines I installed all the
necessary rpm's. I followed the tutorials from the site to configure heartbeat
and everything seems to be ok(I have two working nodes as shown by crm_mon).
Next, using hb_gui I created an IP Addr2 resource cloned on both nodes.
The Ip of the resource is in the same network as the nodes. When the resource
is started it raises a new interface on both nodes(I called it eth0:1 adding a
NIC parameter).
Now when I ping that IP from one of the nodes I get an ICMP reply. One as it
should... If I ping that IP from another host in the same subnet I three
replies. One ICMP reply and two DUPs - duplicated. Shouldn't respond just one
of the nodes maintaining the replicated resource? And how do you explain three
responses - reply + 2 dups ?
Do you have any ideea why this is happening ?
Maybe I configured something wrong...
Alex Gavrila.

If you are just trying to achieve simple failover, you do not need to
use a resource clone. Because it's cloned, it's starting on both nodes
at the same time.
The default behavior of heartbeat is to allow a resource to run on any
node, so there is no need to create the clone.
