On CentOS6.2 I cannot see the cluster when I run luci on that node, luci shows the cluster fine on the other node. Also, when I run luci on the node where it works from I cannot see "uptime&qu... [by Rick_Smith]
Hello Experts,
Please help me with the exact steps on configuring two node cluster on RHEL 6.2,
I failed to configure the simplest cluster by below steps,
1- install RHEL 6.2 64-bit on both nodes
2- add to hosts file of each server ( 1 IP in local NW and another in IP private NW).
x.x.x.x node1-pub
z.z.z.z node2-pub
y.y.y.y node1-pvt
t.t.t.t node2-pvt
3- yum install ricci ( on both nodes )
I am trying to setup an active/passive (2 nodes) Linux-HA cluster with corosync and pacemaker to hold a PostgreSQL-Database up and running. It works via DRBD and a service-ip. If node1 fails, node2 should take over. The same if PG runs on node2 and it fails.

I'd like to build a two or three node Pacemaker cluster that would manage Xen (or possibly KVM) virtual machines.
Is it possible to set up the Pacemaker cluster (or some of its components) in such a way that when all nodes are active the VMs will use all available RAM but when one node fails the cluster will reduce VM's memory to fit them all on remaining nodes?
I'm having trouble figuring out how to configure a 2-node setup with a third
simpler one for quorum.
It seems to think all the nodes have the capability to act as a full fallback node, when I only I want a quorum with STONITH working sanely for what is essentially a 2+1 DRBD-MySQL node system.
Any tips or documentation on how to make the 3rd node just a quorum member would be appreciated.
I'm in the process of configuring a sort-of Beowulf cluster, the major difference being that I want to be able to add nodes from any network. Because of this I can't run DHCP on the server to inventory all the nodes.
New nodes would run a package or script to configure SSH, MPI, NFS and the like. During installation they'll require the IP address of the server.
