Beispiel:
\nFestplatten sind \/dev\/sdc und \/dev\/sdd<\/p>\n

# Partitionieren und als Raid markieren:
\nparted \/dev\/sdc mklabel gpt
\nparted -a optimal -- \/dev\/sdc mkpart primary 0% 100%
\nparted \/dev\/sdc set 1 raid on<\/p>\n

# dasselbe nochmal f\u00fcr \/dev\/sdd
\nparted \/dev\/sdd mklabel gpt
\nparted -a optimal -- \/dev\/sdd mkpart primary 0% 100%
\nparted \/dev\/sdd set 1 raid on<\/p>\n

#
\n# Raid einrichten
\n#
\nmdadm --create \/dev\/md0 --auto md --level=1 --raid-devices=2 \/dev\/sdc \/dev\/sdd <\/p>\n

#
\n# Formatieren
\n#
\nmkfs.ext4 \/dev\/md0 <\/p>\n

#
\n# zu \/etc\/fstab hinzufuegen
\n# (damit das Raid beim n\u00e4chsten Booten gemounted wird:
\n#
\necho \"\/dev\/md0 ext4 defaults 0 2\" >> \/etc\/fstab<\/p>\n

#
\n# Aenderungen permament machen
\n#
\nsu -c \"\/usr\/share\/mdadm\/mkconf > \/etc\/mdadm\/mdadm.conf\"
\nupdate-initramfs -u -k all
\n<\/code><\/p>\n

Allgemeine Anleitung f\u00fcr Ubuntu:

Falls das Raid nach dem Booten nicht geht, hat mit dieser Tipp geholfen:
\nmdadm --stop \/dev\/md
\nmdadm --zero-superblock \/dev\/sd (do this for all your raid disks)
\ndd if=\/dev\/zero of=\/dev\/sd bs=512 count=1 (do this for all your raid disks)<\/code><\/p>\n
