I reproduced it here. The problem is that mdmon isn't running. Simply
try running "mdmon /dev/md127", and the mount should proceed.

oh, ok, I should have noticed.

You'd avoid the problem by running "mdadm -IR /dev/sda" in the first place.

Actually this is how arrays are assembled during boot on some
distributions (Fedora for example). They incorporate disks as they're
discovered and then they run the array (degraded or not). Therefore
booting with a missing disk doesn't work.

Thanks
