Thanks Sunil for this information. I tried going through the docs
mentioned there, they are useful, but there are details which I wanted
for my learning purpose which are not in those docs. It would be
great if anyone can share any good doc mentioning details about
Clustering Services which OCFS2 uses. I know that clustering services
which OCFS2 uses has the following components:<br>
<br>
1. Node manager<br>2. Heartbeat module<br>
3. TCP Protocol module<br>
4. DLM<br>
<br>
But once I install and configure OCFS2, I can see the following modules getting loaded:<br>
<br>
1. configfs (with filesystem mounted)<br>
2. ocfs2_nodemanger<br>
3. ocfs2_dlm<br>
4. ocfs2_dlmfs (with filesystem mounted)<br>
<br>
and the following threads created:<br>
1. ocfs2_wq (perhaps it's the kernel worker thread)<br>
2. ocfs2_vote (for voting requests. Is this the listener thread?)<br>
3. ocfs2_cmt (perhaps this is the node monitoring thread?)<br>
<br>
Can't think of OCFS2 in 10g environment where we have another required
and reliable clustering service CRS (with 10g) running and managing
Oracle's resources. Do CRS and OCFS's clustering services co-ordinate
in some manner or do they take actions independently on their own
during crash and other conditions?<br>
<br>
Any help would be highly appreciated!!<br>
<br>
Thanks.<br>
