That's a key reason.  There are advantages and disadvantages to both
approaches.  It comes down to preferences, mostly.

Using linux-cluster (aka RHCS, in this case)...

- You do not need to provision raw devices for membership (or anything
at all, actually)
- You get the benefits of fencing (for those who are paranoid ;) )
- You can use ext3 as the back-end store for any and all parts of the
database installation.

Obviously, whether any of the above is an advantage to you is a matter
of preference too ;)
