Hi, Sunil or Tao,
I have a 4 nodes OCFS2 cluster running OCFS2 1.2.8 on SuSE 9 SP4. When I tried to do failover testing (shutting down one node), the whole cluster hung (I can not even login to any server in the cluster). I have to bring all of them up and then be able to use the system. What kind of behavior is it? Is it the fence of OCFS2? Below is my configuration. aopcer13:~ # /etc/init.d/o2cb status Module "configfs": Loaded Filesystem "configfs": Mounted Module "ocfs2_nodemanager": Loaded Module "ocfs2_dlm": Loaded Module "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ERP_UAT_APPS_OCFS2: Online Heartbeat dead threshold: 300 Network idle timeout: 60000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Active Please help. If you need more information, please let me know. Regards, Howard(Kuiyang) Kuang Principal Systems Engineer Linux Engineering - WHQKT United Airlines
