I am setting up a two node active/passive cluster to provide DHCP/DNS services, using CentOS 4 U2 and RHCS4. The rpms were compiled from srpms using the info provided by Sean Gray (thanks, Sean). The shared storage is on a NetApp filer using ISCSI. I think I've missed something somewhere. The output from clustat and clusvcadm: [root@ns1-node1 ~]# clustat Member Status: Quorate Not a member of the Resource Manager service group. Resource Group information unavailable; showing all cluster members. Member Name State ID ------ ---- ----- -- ns1-node2.mydomain.net Online 0x0000000000000002 ns1-node1.mydomain.net Online 0x0000000000000001 [root@ns1-node1 ~]# clusvcadm -m ns1-node1.mydomain.net -e DNS Member ns1-node1.mydomain.net not in membership list Any help/advice will be greatly appreciated. TIA. -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
