Although the segfault is probably less than ideal, the nanny process killing the node is probably fine since the node needs to be fenced at this point anyway. What should of happened with rgmanager is: * it should have seen a negative quorum transition, * halted cluster services uncleanly, and * wait to be fenced. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
