Mind if I ask why you suggest this rather than the new storage groups  
feature within Myth?

LVM is very useful for allowing the o/s & applications to see a  
number of drives as a single mount-point / directory, but a failed  
drive can surely h0se all of the recordings on all of the drives. As  
I understand it "storage groups" allows Myth to use several  
directories for storing its files, and the failure of one drive  
leaves recordings on the others unaffected. Basically, as I  
understand it, "storage groups" is a more "Mythy" way of using  
multiple drives in a non-redundant way (I am not so retentive as to  
regard my TV recordings as important enough to justify RAID) than LVM.
