[mythtv] Is there a way to string together different hard drives for storage in MyThTV?

[Chuck Wolber]

Consider using LVM instead of RAID in this case. LVM allows you
aribtrarily string together as many hard drives as you want without having
to take down your system or worry about having to reformat to make a
partition larger (IE add more disk). Works great in RedHat 7.3 and 8.0 (I
suspect others too, but I have only used it in those two).

A good lvm HOWTO can be found here:

I'm also happy to help if that isn't clear enough for you. LVM on Linux is 
actually surprisingly easy to use.
