am i getting this right: a raid config stored under 5.3 will probably
not get corrupted???

as i had problems with an nfs-server (with SiI0680) running 5.2 for no 
obvious reason, i upgraded to 5.3 - and did not encounter the above 
mentioned problem since the release of 5.3 to date. i had to recreate 
my raid configuration, though, which seemed not to harm my data.
(like this: atacontrol create RAID1 ad4 ad6)
is this the expected behaviour: doesn't recognise raids created under
5.2, but works fine with raids created under 5.3?

wondering,
Volker.
