Red Hat's CLVM suite is a heavyweight high-availability system based on CMAN and depends on fencing of failing nodes. I've never been happy with it, especially since we lack a proper out-of-band way to do fencing from one node to another. After a couple of gruesome evenings kicking this around I found a better solution in [http://pixelchaos.net/2009/04/23/openais-an-alternative-to-clvm-with-cman/ openais]. This is based on building a quorum of nodes in order to do locking; the only processes required are corosync and clvmd. | Red Hat's CLVM suite is a heavyweight high-availability system based on CMAN and depends on fencing of failing nodes.
