I was using the version as installed by 5.3-BETA7-i386-disc1.iso downloaded 
on 3rd October..   I did notice that it didn't spot the array already 
present on the drives from a 4.10 test installation, but assumed that was 
because of the different versions.  My worry is that it doesn't spot a raid 
array that it created itself!

I'll download the miniiinst, and see how that fares tomorrow, and will also 
read up on gmirror.  I've not really delved into pure software raid much, 
after scrubbing a couple of discs trying to get  vinum going :-) - I'd 
bought the 0680 cards initially thinking it was a proper hardware raid, but 
it seemed simple enough to get going with atacontrol under 4.10 - I just 
didn't expect to get any problems with 5.x when setting up another machine.

Thanks for the suggestions,

Rob.
