Just my 2 ¢ here. I do not pretend to have the TRUTH ....
Said you've 2 identical drives for the system.
Set up  2 partitions onto them exactly the same.
The fisrt one,  small will be used for /boot
The second one for everything else using LVM.
Set up software raid to make a first mirror of the two /boot
and another one for the LVM.
This way, you can boot and run your machine from any disk and you can 
even do a backup by splitting the raid....
IT has always worked except on my home machine where I was unable to 
insatall a Fedora system using software mirror AND lvm ..; Go figure ;-)
