Ok, I rebooted the ols Slackware system and the array assembles fine there. The point was that debian didn't see the partitions sda1, sdb1 and sdc1 for reasons beyond me. c/sfdisk reported the partitons fine but they weren't in /proc/partitions, Bob knows why. So when debian scanned the disks, it saw an old UUID from my first raid steps when I made the entire disk part of the raid instead of setting up an 0xFD partition, guess the old UUID is somehow still around. Questions that remain are: why doesn't debian see the partitions and how do I get rid of the old relicts from the first try?
