Comment 31 for bug 1611277

So am I able to switch from dmraid to mdadm to control the raid1 without affecting the hard drive in Ubuntu 14.04.4?

Because when I do a fresh install of Ubuntu 16.04.1, which comes with Kernel 4.4.0-34, mdadm (pre-installed in 16.04.1 already) says my raid device does not have recognized superblocks. If I try to load the disk directly, it will give me a unknown type ddf_raid_member.
