Hi, it worked (kind of). Thanks. I was able to recreate (the all appear in /proc/mdstat) and in the rescue I've mounted the /boot which maps to /dev/md0. But I can't mount any other partition. they all complain with the same error mount: Mounting /dev/mdX on /tmp/mountpoint failed: no such file or directory Any ideas?
