Do they all "See" each other before you power off node 1 (where 1 == A) ? Apart from having a node with 2 votes, the rest of the concept is pretty similar to qdiskd's design for "all-but-1 die" case. Expected behavior is that any of the following constitutes a quorate cluster: A+Qdisk (4 votes) B+Qdisk (4 votes) C+Qdisk (4 votes) A+B+Qdisk (5 votes) A+B+C (4 votes) A+B+C+Qdisk (7 votes) Effectively, you want to look at 'cman_tool status'. Before losing a node, you need to verify that each sees 7 votes. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
