Weird. Did you happen to try a 'cat /proc/mdstat' after the rescue boot, or a 'dmesg' to see what the kernel actually saw during bootup? The only time I've seen something like this is when I've forgotten to set the partition types to FD or the /etc/fstab entries didn't match what the booting kernel would find. -- Les Mikesell lesmikesell@xxxxxxxxx
