Ocfs2 users - Oct 2007 - OCFS2 with clusterware

Hi Folks.

I am wondering how would fencing in conjunction with Clusterware and OCFS2
works?

I have a 2 Node setup with some 3rd Party Apllications and some Oracle 9iR2
DB?s.

Clusterware should manage the Applications and do the failover. The shared
storage should work with OCFS2.

The problem will be that we make use of two cluster management software
services. I am going a bit nervous thinking about the situation, that the
cluster services may do some different decisions concerning fencing. In worst
case, we will have a very expensive up and down game.

So my Idea is, to disable the fencing with OCFS2 and make the clusterware to the
primary cluster manager.

1. Does OCFS2 work in conjunction with cluster ware?
2. Is it possible and should I disable the fencing with OCFS2?
3. Is there some experience with clusterware and OCFS?
4. Is there documentation?
5. Any other suggestions?

Thanks in advance?

Typically what you just do is tune the timeouts in Ocfs2 and Clusterware
such that Ocfs2 fences and recovers before Clusterware even realizes that a
node is gone.
