Truly courageous :)

Kidding!!


raid5 can grow already - both size of disks (ie replacing each existing
disk with a bigger one) and more recently, number of disks.

There's not been much traffic about it - but what there has been has
been good.

You'll need a very recent kernel/mdadm though... and a backup is always
recommended.
