Speaking of... If I already have a cluster set up that split brained itself (but the services are still running on one, and it wont un-split brain with the other box up...) how hard would it be to add a quorum disk? I guess I could post my whole problem and let smarter people figure out what I broke. -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of gordan@xxxxxxxxxx Sent: Wednesday, April 02, 2008 11:13 AM To: linux clustering Subject: Re: Why my cluster stop to work when one node down? > Nice Gordan!!! > > It works now!! :-p You're welcome. :) > "Quorum" its the number minimum of nodes on the cluster? Yes, it's the minimum number of nodes required for the cluster to start. This is (n+1)/2, round up number of nodes defined in cluster.conf. This ensures that the cluster can't split-brain. In the 2-node case this needs to be adjusted which is what the two_node parameter does. There's higher risk of splitbrain, though, but you can use tie-breakers of some sort.
