craig, u can grow via md which is what u do first, then grow the fs.
ex;
mdadm --grow ... to add a drive
then,
mdadm --add ... to gorw the raid onto it
then,
pvresize ... to grow your filesystem onto it.
atleast this is how i've dun it.

you must format those drive to the desired fs after raiding them
Those where my initial thoughts, damn it! Hmm, going to have to bring a sand box server home from work, oh the hassle. Thanks for the confirmation though. ...
md (software raid mechanism or watever u wanna call it) allows u to grow so if your raid is formatted with an fs that allows u to grow, then u r good to go (lvm will allow u to grow).
This was also my current belief, again thanks for confirming that.
you will not be able to add more physical drives to an existing RAID-5 array. You can however, add new available storage space (RAID or drives) to an existing LVM partition with some of the LVM commands.
Just so we are clear...
RAID is physical drives. LVM is a partitioning scheme.
