We want to expand a Dell Poweredge 2800 with 2 disks in the front
(essentially what could be ordered as an option when new).

We already have 8 300GB disks inside in a Raid5 array on the built-in
PERC 4/di controller.

Is it possible to expand the existing RAID5 array without destroying

Or do we have to go the backup, destroy-reinstall, restore route?

Yes, we are awaiting a reply from Dell, too, but I'd like to hear
about in-the-field experiences as well :-)
