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.

Upgrade to OCFS2 1.2.9-1 shipping with the latest SLES9 SP4 kernel (2.6.5-7.312). http://download.novell.com/Download?buildid=27kCZ1qWwWo~ You are most likely hitting bug#6680001 as mentioned here. http://oss.oracle.com/projects/ocfs2/news/article_17.html Also, you might want to tone down the heartbeat threshold from 10 mins to 1 or 2 mins. http://oss.oracle.com/projects/ocfs2/dist/documentation/ocfs2_faq.html#TIMEOUT If you still have problems, log a bug with Novell. We may need more details. Sunil Kuang, Howard [WHQKT] wrote:> > Hi, Sunil or Tao, > > > > I have a 4 nodes OCFS2 cluster running OCFS2 1.2.8 on SuSE 9 SP4.

Sunil, ? This applies only to subdirectories or also to the number of files inside a directory? ?? Oracle Applications can easily have hundreds of thousands files inside the concurrent output and log directories.

subdirs only. No limit on the number of files in a dir or in a fs. No limit on the number of dirs in a fs too.
