two RHEL 5.4 clusters on same Network segment
Two years ago, I have set up two node Active-passive cluster on VSphere 4.0 and it is in production ever since.
I've tried to setup another cluster for testing purposes on the same VSphere, and failed.
And what is interesting is that those new two nodes came up with cluster.conf of the production cluster, even though I did not try to bring them in the existing production cluster.
I googled a bit and found something stating that two different clusters might behave strane if on the same network segment.
Question is, did anyone try to create two different clusters on the same hardware, or on the same network VLAN?
I will do some more digging after weekend, and get back to you.
generally you wouldn't run cluster services on a production interface, you would generally expect to add a dedicated cluster vlan for each clusters interconnectivity.
