Good catch.  /dev/sda1 was a scsi device in a former life.  Correcting
that fixed the problem.  Thanks!

Hello,

I tried to create a raid device starting with

foo:~ 1032% mdadm --create -l1 -n2 /dev/md1 /dev/sda1 missing
mdadm: /dev/sda1 is too small: 0K
mdadm: create aborted

Quick sanity check, is /dev/sda1 still a block device node with major
number 8 and minor number 1, i.e. does the following fix the issue?:

mknod /dev/sda1 b 8 1

Thanks,
