We just recently compiled a new 2.6.8 kernel with GFS support. Can I still use the old userspace tools that we were using on 2.6.7? I'm having problems running the cman_tool join command after I start up ccsd. The message I'm getting is: [root@testhost1 cluster]# cman_tool join can't open cluster socket: Address family not supported by protocol Doing a tcpdump shows that it's only trying to hit 127.0.0.1 which might explain the address family bit. Here's my cluster.xml: <?xml version="1.0"?> <cluster name="cluster1" config_version="1"> <cman two_node="1" expected_votes="1"> </cman> <nodes> <node name="testhost2" votes="1"> <fence> <method name="single"> <device name="human" ipaddr="10.0.0.234"/> </method> </fence> </node> <node name="testhost1" votes="1"> <fence> <method name="single"> <device name="human" ipaddr="10.0.0.233"/> </method> </fence> </node> </nodes> <fence_devices> <device name="human" agent="fence_manual"/> </fence_devices> </cluster> Both hosts are in our DNS server. Any ideas? Looking to stay away from compiling userspace tools. Thanks in advance. Jim
