Here is my real life situation at home:
I have:
2x) 300GB PATA disks
1x) 500GB SATA
1x) 13GB ubuntu system drive

My interest is to make one large space out of the 500 and 300 GB disks - I understand I can do this with LVM.
I also know I can make a hardware JBOD.
That is the extent of my RAID "knowledge"

Here is my question:
Is there a storage technology that will allow me to have multiple disks connected into one large disk - and then GROW later as I add more disks  - WITHOUT- having to reformat the entire array?

For example: I set up my 1.1TB JBOD with my disks now, and fill it up. Then I go but a nice 750GB hard drive -  - obviously i cannot backup my 1.1TB of data anywhere - so can I somehow add the 750GB right in without upsetting my existing data?

All of my limited research points to no - i would have to reformat the entire array and start over anytime I added a disk.

Isnt there some kind of adaptive RAID?
