Per,
Hi Jan
Many thanks for your response.
I spent some more time on this yesterday so I found out that the nodes
needs really to have 2 nics, 2 ip's and the resource ip gets assigned to
the node that becomes the running node.
You don't need two nics. Even tho it's better, because you have
separated cluster traffic from app traffic.
I have setup vmware fencing for each node, but I could not see anything in
the configuration to allow or disallow one node to fence of the other or
does this happen automagically? apologies if the question seem a bit stupid
Yes, it is happening automatically as long as you've configured fencing
for every node.
but 1 week ago I started this project with very little experience in
clustering :)
That's why I'm recommending you to ask linux-cluster@xxxxxxxxxx and read
some docs
(https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/High_Availability_Add-On_Overview/index.html).

it looks like none of your question is really corosync related (so I'm
CC'ing linux clustering <linux-cluster@xxxxxxxxxx> (this is really
better list) but I will try to answer at least some of your questions.
Hi all
I have redhat clustering running on a 3 VMware vm's 2 nodes and 1
management server I can join the nodes without any problems but I got a
couple of questions that I hope someone here can shed some lights on for
me.
If I want to add a ip resource to the cluster must both nodes be
configured
with a interface with that ip or is there a better way of doing it? If
not
You must make sure that NO nodes has this address assigned. IPAddr
resource will take care to add ip to interface.
then can one of the nodes have the nic in standby?
I don't think this is supported by any resource script.
How do I add fencing for a VMware vm's I notice that there is the VMware
soa must the each vm be configured with its individual VMware soa fencing
or is fencing not needed? From what I can read fencing is needed.
Every node must be able to fence any other node. So you have to
configure fencing method for every node.
In theory fencing is not needed as long as you are not using shared
storage, but it's still better to have it.
I am using Centos .6.5 with ESXI 4.1
Many thanks for your time
