How do you access those disks? Do you have /dev/sd[ab][13]. Is it some
kind of VM? If none of /dev/sd[ab][13] /dev/sd[ab] exist it probably
means that there is a bug in udev. Mdraid detection is probably done in
kernel and so presence of nodes under /dev is irrelevant. But any action
attempted with devices from userspace is obviously bound to fail.
