So I zero the superblock and do the create, and get this error: comp3:~# mdadm --zero-superblock /dev/hde4 /dev/hdf4 /dev/hdg4 /dev/hdh4 mdadm -v --create /dev/md4 --level=5 --raid-disks=4 /dev/hde4 /dev/hdf4 /dev/hdg4 /dev/hdh4 I was at the console when it happened, it indicated a could not access error. When I ran zero-superblock twice, and then tried it again it worked flawless. At least I know the correct syntax.
