If I try
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sdc /dev/sdd /dev/sde /dev/sdf
I have this error:
mdadm: layout defaults to left-symmetric
mdadm: chunk size defaults to 64K
mdadm: /dev/sdc appears to be part of a raid array:
level=raid5 devices=4 ctime=Mon Nov 20 14:48:46 2006
mdadm: /dev/sdd appears to be part of a raid array:
level=raid5 devices=4 ctime=Mon Nov 20 14:48:46 2006
mdadm: /dev/sde appears to be part of a raid array:
level=raid5 devices=4 ctime=Mon Nov 20 14:48:46 2006
mdadm: /dev/sdf appears to be part of a raid array:
level=raid5 devices=4 ctime=Mon Nov 20 14:48:46 2006
mdadm: size set to 143374656K
Continue creating array? y
