mdadm –build saves the day!

yes, this made my /home on my desktop mountable again!

mdadm --build -c8 --level=0 --raid-devices=2 /dev/md1 /dev/hda5 /dev/hde5

Debian or Ubuntu overwrote the RAID superblock obviously. It’s funny how it really doesn’t work well when you silently change the stripe size of a raid volume.
