I'm sure I read somewhere, that the current code is considered beta.
If I'm making that up, It's implied by the fact that the DLM is quite

It is if you've got shared storage that implements raid.

I'm sure Red Hat's product for RHEL is nice, stable, and production
ready. You are playing with relatively fresh code.
