[Ocfs2-users] future of ocfs2

[Jeremy Schneider]

At the company where I'm working right now, I'm part of an architecture 
effort to come up with our standard design for RAC on Linux across the 
firm. There will be dozens or possibly hundreds of deployments globally 
using the design we settle on.

We're internally debating whether or not we should include OCFS2 in this 
design right now, and I'm curious if anyone has arguments one way or the 
other to share. Our standard design on Solaris does utilize a cluster 
filesystem and we would welcome a similar design, but there are some 
concerns about the readiness, stability and future of OCFS2.

OCFS2 is being considered for these four use cases:
- database binaries (vs local files or NFS)
- diag top (11g) or admin tree (10g) (vs local files or NFS)
- archived logs
- backups

Other files will be stored in ASM.

I have seen mention in blogs such as 
http://bigdaveroberts.wordpress.com/ of something called ASMFS in 11gR2 
and I'm wondering - will this feature (if included) have any impact on 
Oracle's commitment to OCFS2 development? Could Oracle conceivably 
develop a whole new cluster filesystem and put their full weight behind 
it as they did for ASM storage, leaving OCFS2 as a lower priority for 
new features and improvements? Has Oracle demonstrated significant 
commitment to OCFS2 development and support in the past, and is this a 
mature enough technology for wide-scale deployment?

Just looking for opinions. :)

Thanks,
Jeremy
