I have had much the same problem. The Red Hat 9 startup scripts find the first level of raids (the Raid 1's), but then don't do a second pass to assemble the Raid 0 made from the two sets of Raid 1's. In my config file, they are in the order I would expect to work... Please post any info about this to the list, thanks!
