We plan to use OCFS2 in a project running Red Hat Enterprise Linux (RHEL) 5.6 because we found OCFS2 to be much simpler to set up than GFS.

I am, however, worried about the upgrade process since I understand OCFS2 depends on the kernel version number. If I perform yum update on my RHEL host I might receive a newer kernel version. What would be the correct way to keep OCFS2 updated and working?

What is the best practice to have an OCFS2 system that runs a long time and also gets kernel updates?

I just saw that the guys are Oracle have only made OCFS2 available for their own kernel. I cannot see the source to it or patches for the vanilla kernel anywhere on their website. Am I missing something? – wzzrd Apr 15 '11 at 13:37
Hi, you can grab OCFS2 off their project website. Just make sure you get the right kernel version then you can use it with RHEL/CentOS, etc. – Stephan Apr 18 '11 at 15:01
Yeah, I should have said "the 1.6 version of OCFS2". The older version (1.2 and 1.4) are available as source downloads and (as I see it) have been merged upstread. If anyone can point to a source download of the 1.6 version of ocfs2, that would be grand. – wzzrd Apr 19 '11 at 7:44

We have exclude = kernel* in our yum.conf file to avoid this exact problem. I should add that we only kernel update when there is a urgent need to do so and when oracle blesses the kernel

Are you sure? AFAIK, the whole point of RHEL is not to change anything on the same system release. You just get bugfixes, not upgrades.

Unfortunately I am sure. Also RHEL bounces you from 5.5 to 5.6 without you really noticing. I have had several kernel updates during the last few months. You can imagine my surprise when I found out. – Stephan Apr 13 '11 at 19:37
