[Ocfs2-users] RAC and OCFS2 timeout interaction issues

[onedbguru at gmail.com]

If you move to 11.2.0.1 you can put ocr, voting AND shared binaries and/or fra in ASM/ACFS.  A much cleaner implementation.

Here are some hints:

-       Starting with versions 1.2.5 and later, the ocfs2 network timeout
may be configured. 

-       If using network bonding, you should set the network idle timeout to
at least 30 seconds.

-       Set O2CB_IDLE_TIMEOUT_MS to at least 30000. If the problem persists,
set it to 60000.

We have a RAC cluster as follows:

*	3 nodes with RHEL5, Oracle 11.1.0.7, and OCFS2 1.4.2 
*	Voting and OCR are on OCFS2, all other shared storage is on ASM 
*	Storage hardware is provided by a fibre-channel SAN fabric 
*	Interconnect uses two bonded NICs per server, connected to different
blades on a single switch

Previously we had an issue where all three nodes would reboot if one node
had problems. This
