Hello, I have a cluster 3 on 2 x F11 x86_64 nodes. main components are: fence-agents-3.0.0-14.fc11.x86_64 clusterlib-3.0.0-20.fc11.x86_64 resource-agents-3.0.0-12.fc11.noarch lvm2-cluster-2.02.48-2.fc11.x86_64 modcluster-0.16.1-1.fc11.x86_64 corosynclib-1.0.0-1.fc11.x86_64 cman-3.0.0-20.fc11.x86_64 corosync-1.0.0-1.fc11.x86_64 rgmanager-3.0.0-20.fc11.x86_64 It seems that on both nodes modclusterd is not able to start with this log in /var/log/clumond.log Mon Aug 3 17:04:31 2009 clumond: started Mon Aug 3 17:04:31 2009 clumond: unhandled exception in main(): ServerSocket(port=16851): socket() failed: Address family not supported by protocol Mon Aug 3 17:04:31 2009 clumond: died If I try to manual restart it (with cman, rgmanager, ricci aleady started and up), I get: [root ~]# service modclusterd start Starting Cluster Module - cluster monitor: Setting verbosity level to LogBasic [FAILED] Is this service supposed to start automatically (aka chkconfiged on) in cluster 3? In rh 5.3 my chkconfig situation is this: cman 0:off 1:off 2:on 3:on 4:on 5:on 6:off modclusterd 0:off 1:off 2:on 3:on 4:on 5:on 6:off openais 0:off 1:off 2:off 3:off 4:off 5:off 6:off qdiskd 0:off 1:off 2:on 3:on 4:on 5:on 6:off rgmanager 0:off 1:off 2:on 3:on 4:on 5:on 6:off ricci 0:off 1:off 2:on 3:on 4:on 5:on 6:off and when I have it: clvmd 0:off 1:off 2:on 3:on 4:on 5:on 6:off So that when I have to do maintenance on a node, leaving it open but without cluster infrastructure active I do : 1) eventual relocation of active services 2) stop of related services: service modclusterd stop service rgmanager stop service ricci stop service clvmd stop (if present) service qdiskd stop service cman stop At this moment in my F11 nodes I have the same chkconfig setup for these services (apart from qdisk that I have not configured at the moment). Has been changed anything in startup scripts config setup? Also, Description for modclusterd init script: # description: Starts and stops Ricci Cluster Module - cluster monitor Description for ricci init script: # description: Starts and stops Red Hat Cluster and Storage Remote \ # Configuration Interface (ricci) Not very clear (at least to me) what are the relative functions of these two services.
