Things have slowed a little in that department at the moment as my main test hard disk underwent a 
rapid deceleration test from a table to a tiled floor and has somewhat ceased to function. (Don't 
try this one at home kids)

Prior to that I had got as far as intermittently creating raid-6 volumes that worked (the rest of 
the time the blocks were all intact but in the wrong order!) and kludging it to work with raid-5 
volumes over 2TB. (I did manage to reconfigure a 1.6TB array to be a 2.1TB array with no data loss).

I have a new set of test drives in my purchase queue, but have not quite got that far yet.

The raidtools-1.00.3.tar.gz package is the one I have been working with and seems to be pretty 
stable on anything under 2TB. I certainly did not hit any major flaws while working with it as is.

I'm currently thinking about how to do it while removing the dependency on raidtools and moving to a 
mdadm like setup, but have not got far down that path.

If you want to use raidreconf and you created your arrays with mdadm then use lsraid to generate a 
suitable raidtab, edit that to create the new one and have at it.
On <2TB I found it pretty solid.
