(Note this is a resubmittion since I had a wrong reply address) I was wondering if anybody has information on this. I have 2 node cluster and some shared storage between two nodes. The manual contains some information on the shared storage setup: http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-hardware-cluster.html#S2-HARDWARE-STORAGESETUP Section 2.5.3.1 at http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-hardware-connect.html. However I could not find a way to tell the cluster to use my raw devices and also test that any of these devices are being used. I also use my cluster w/o any shared devices and it seems to work. But in this case a 2-node cluster requires a quorum devices (usually shared storage) - I can see that when one node is down I still have a quorum w/o using any shared storage. So my questions are: 1. Do I have to have a shared storage? 1.a If yes then how do I configure and test it? 1.b If no then how is the quorum is achieved in 2-node cluster when 1 node is down?
