There's no need to do anything to the filesystems. Later OCFS2
versions are backward compatible with earlier versions. I'm not
sure if there were any new features introduced in the latest OCFS2
version for EL5, but I'm pretty sure that all OCFS2 1.4.* versions
have the same network protocol, so you can do a rolling update
(install on node 1, reboot, install on node 2, reboot) without
having to unmount the fs on all nodes first.<br>
<br>
Thanks,<br>
Herbert.<br>

<p class="MsoNormal">First of all, why bother update to 5.5,
when you can
update to 5.8? Many bugs have been fixed since 5.5. Do you
really
want to run into those?<br>
<br>
OCFS2 and the kernel have to be upgraded at the same time. In
other
words, you have to make sure you install both the kernel and
the OCFS2 module
that goes with it at the same time, then you reboot into the
new kernel with
the new OCFS2 module. The easiest thing to do is to just run
yum update,
and let it update to the latest package versions, and then
install the OCFS2
package for the kernel that got installed.<br>
