I made plenty of RAID1 systems w/ ide disk: OK. Now I tried a SCSI system and I can't make the kernel recognize the partition to make into an array. Of course partitions are 'fd': raid autodetect. Kernel recognizes the scsi hw (aic7xxx compiled in), then starts "md: Autodetecting RAID arrays" that will just fail to find the arrays. If I start from a live CD, I can "mdadm -A /dev/md0 /dev/sda6 /dev/sdb6" and the array starts and I can mount it. Is there something peculiar of SCSI systems I'm just ignoring?
