[Ocfs2-users] Kernel panic when deleting a file

[Sunil Mushran]

Or, you could upgrade one node from rhel4 to rhel5 u3 and install
ocfs2 1.2.9. That node could then be brought online. Repeat the
process until all nodes are on rhel5 u3.

Then shutdown the entire cluster and upgrade all nodes to 1.4.7.
Bring them back online.

The last step would be to upgrade the nodes, one by one, from u3 to u5.
