Hi all, Could someone point me to design doc for OCFS2? I could get OCFS V-1 design doc, but could not find any design doc for OCFS2. I read somewhere that OCFS2 has got lots of design changes as comapared to OCFS1. Thanks in advance.

[Ocfs2-devel] Please help me in getting OCFS2 design doc.
Look into docs in ocfs2 projects page. While there is no design doc, there is a presentation which lists out the changes. http://oss.oracle.com/projects/ocfs2/documentation/ Sum Sha wrote:> Hi all, > Could someone point me to design doc for OCFS2?

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: 1. Node manager 2. Heartbeat module 3. TCP Protocol module 4. DLM But once I install and configure OCFS2, I can see the following modules getting loaded: 1. configfs (with filesystem mounted) 2. ocfs2_nodemanger 3. ocfs2_dlm 4. ocfs2_dlmfs (with filesystem mounted) and the following threads created: 1. ocfs2_wq (perhaps it's the kernel worker thread) 2. ocfs2_vote (for voting requests. Is this the listener thread?) 3. ocfs2_cmt (perhaps this is the node monitoring thread?) 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? Any help would be highly appreciated!! Thanks.
