I think it is better to leave these as two separate HowTos because they describe two different setups. The traditional one is well supported by default CentOS, but requires more effort in case of failures. The partitionable raid is more fault tolerant but requires patching mkinitrd (check http://bugs.centos.org/view.php?id=3566). > > Maybewe can merge the two documents somehow, but before thinking about > > that, I need to know what is in the article :) And what about the second guide?
