You should be able to use spinlock to do this, I'm sorry you'll have
to find more on this on your own.  However this WILL decrease the life
of your drives.  Drives are much happier staying on (assuming the
proper environment) than coming on and off.
As Paul said using an LVM increases your change of data loss with
every drive you add.  That said I use it, but I don't hold a high
price on my tv recordings and I have everything else running nightly
backups.  There's a chance when your LVM fails (provided its not
striped) that you will not suffer complete data loss.
