Hi list, I have a question concerning number of OCFS2 volumes per cluster.
>From our storage vendor we received recommendations how to configure mount volumes per database to gain the best possible performance. Basically, we should separate redo logs,archive logs, temp, data, etc. This is not hard to configure but I'm concerned about this line that I've found on Oracle support site: Linux OCFS2 - Best Practices [ID 603080.1] Number of volumes The mounting of too many OCFS2 volumes (i.e. 50 or more) per cluster is likely to create a performance (process) bottleneck - this is not specifically related to OCFS2. Ideally, it is desirable to have no more than around 20 OCFS2 partitions per system. See also http://oss.oracle.com/bugzilla/show_bug.cgi?id=992 In our configuration we would need more than 60 OCFS2 mount volumes per cluster so I don't know should we expect any performance problems due to the number of OCFS2 volumes? What is your recommendation about number of OCFS2 volumes per cluster regarding performance and stability? Our kernel and ocfs2 version: # uname -rvp 2.6.18-274.0.0.0.1.el5 #1 SMP Mon Jul 25 14:33:14 EDT 2011 x86_64 # rpm -qa|grep ocfs2 ocfs2-tools-1.6.3-2.el5 ocfs2-2.6.18-274.0.0.0.1.el5-1.4.8-2.el5 ocfs2console-1.6.3-2.el5 Thank you very much for your help.
