The hardware (and maybe the software too) must support hot-swap. > Assuming that I have a hot-swap disk in my machine and a spare disk on > my shelf, and that I was not using RAID or anything special on that > disk, would I need a special controller or customizations to the OS to > use it (i.e. be able to take out the failed drive and stick in the new > (formatted) drive)? Is hot-swap only for RAID arrays? Hot-swap is most useful when the missing data that was located on the failed disk can be auto-regenerated, either from a mirror disk or using a parity disk. > Hardware RAID: Hardware RAID is independent of the operating system, > right?

Ideally, yes, although the OS could possibly need to control some functions.

I believe Theodore Ts'o is working on writing (or is planning to write) a filesystem expansion program for ext2.
