Q. Can I use LVM or MD to create my OCFS filesystem on top of it?*
A. LVM and MD are not cluster aware and it makes it very difficult to
manage in a cluster environment. No tests have been performed using LVM
or MD. It may work, but it also may not. Corruptions are likely to
happen since they are not cluster aware software.*
