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 ;) -- Lon -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
