Hello everyone, I was asked to investigate why the rgmanager is not running on a red hat cluster. The cluster is on RHEL 5.3. #rpm -q cman rgmanager cman-2.0.98-1.el5 rgmanager-2.0.46-1.el5 Currently cman is running, rgmanager not. # clustat Cluster Status for prod-clust1 @ Wed Jul 13 15:42:16 2011 Member Status: Quorate Member Name ID Status ------ ---- ---- ------ pnl-p 1 Online psd-p 2 Online, Local # cman_tool status Version: 6.1.0 Config Version: 14 Cluster Name: prod-clust1 Cluster Id: 3382 Cluster Member: Yes Cluster Generation: 1136 Membership state: Cluster-Member Nodes: 2 Expected votes: 1 Total votes: 2 Quorum: 1 Active subsystems: 7 Flags: 2node Dirty Ports Bound: 0 Node name: pnl-p Node ID: 1 Multicast addresses: 224.0.0.1 Node addresses: 10.0.0.2 # cman_tool services type level name id state fence 0 default 00010002 none # service rgmanager status clurgmgrd dead but pid file exists this is the situation on both nodes. for one of the nodes I cannot see any message from rgmanager, and it was confirmed that the error is older then the oldest log file. on the other node I can see the messages when rgmanager was started (after reboot) and here they are: messages.3:Jun 26 02:00:13 node-pnl-01 clurgmgrd[8720]: <notice> Resource Group Manager Starting messages.3:Jun 26 02:00:13 node-pnl-01 clurgmgrd[8720]: <err> Error storing ip: Duplicate my question is what the second line means and what are the consequences? Is it possible that a duplicate IP would shut down the rgmanager? because after a few seconds (25 seconds as we can see) I can see the following: messages.3:Jun 26 02:00:35 node-pnl-01 clurgmgrd[8720]: <notice> Shutting down and later on: messages.3:Jun 26 02:00:59 node-pnl-01 clurgmgrd[8720]: <notice> Shutdown complete, exiting Right now it is not an option to start the rgmanager and test. I have to figure it out only from the log files. Thank you in advance for any ideas. Laszlo -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
