Hello. We have a strange situation with rgmanager on a two node (active/passive) cluster, on physical servers. Nodes are N1 and N2. Out investigation is to simulate how the cluster will react after a kernel panic of the active node. Kernel panic is "simulated" with echo b > /proc/sysrq-trigger Fence agent used: fence_scsi Common storage is: EMC (with powerPath installed on both nodes) The scenarios are: S1. Active node is N1 passive mode is N2 After kernel panic of N1, the N2 resumes the services previously run on N1 (Expected behavior). N1 re-boots and after a while re-joins the cluster. (Expected behavior) S2. Now, active node is N2. We perform a kernel panic on N2. N1 resumes (correctly) the services previously run on N2. After the reboot of N2, cman starts OK (with all other processes), as well as clvmd. But the rgmanager process seems to hang and in 'ps' it appears three times (the normal is two). The logs from N2 show: rgmanager[4985]: I am node #2 rgmanager[4985]: Resource Group Manager Starting rgmanager[4985]: Loading Service Data ps -ef | grep rgmanager root 4983 1 0 15:19 ? 00:00:00 rgmanager root 4985 4983 0 15:19 ? 00:00:00 rgmanager root 5118 4985 0 15:19 ? 00:00:00 rgmanager Versions: rgmanager-3.0.12.1-19.el6.x86_64 cman-3.0.12.1-59.el6.x86_64 corosync-1.4.1-17.el6.x86_64 fence-agents-3.1.5-35.el6.x86_64 clusterlib-3.0.12.1-59.el6.x86_64 lvm2-cluster-2.02.87-6.el6.x86_64 Any help appreciated.
