Quorum says that the should be *more* than half of the original nodes. If a even numbered cluster splits into two halfs none of the nodes has quorum. Quorum will never work in a two-node cluster. Same applies to even-numbered clusters distributed even over two computer centers. Greetings, -- Dr. Michael Schwartzkopff Guardinistr. 63 81375 München Tel: (0163) 172 50 98
