That's right you'll found your cluster partitioned and if you "<cman two_node="1" expected_votes="1">" as redhat setting our cluster maybe you get data corruption
Because every node can operate with one vote an rich the quorum state Forse the fencing problem redhat implement a work around as permanent solution fence delay for some cluster agents For fence_scsi in Redhat 5.X the redhat support says it's ok for production BAAAAA not tre AND i the redhat technical tells the cluster don't require the quorum disk UMMMMMMMMMMMMM Il giorno 12 aprile 2012 16:47, Daniel Bourque <[email protected]>ha scritto: > A qdisk is just another way to maintain quorum in cluster. there is a > special two node cluster mode designed to allow for quorum to be maintained > by the surviving node. > > <cman two_node="1" expected_votes="1"> > </cman> > > But it's not very clear to me what happens with fencing if both nodes > get partitioned on the network.
