The 14.01.x output is not that surprising, dmraid is setting up the raid1 as device-mapper targets. The problem is that dmraid has been abandoned upstream. So the package is unchanged since 14.04 (that could mean it does not even compile anymore).
So there might be some options: 1. Sicne mdadm is supposed to be supporting ddf signatures, the question is was the user-space side actually installed on upgrade (package name mdadm)? If it is installed, then at least in 14.04 there were boot options (either /etc/default/grub or some file in /etc/default/grub.d) that were used to modify handling of ddf signatures. So maybe those need to change, then run update-grub and reboot. 2. The other possibility would be to force a re-compile of dmraid in 16.04 and see whether that works or needs fixing. I could do that but I cannot promise how quickly I get to it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611277 Title: Kernel Shipped With Ubuntu 16.04.1 Cannot Recognize fakeRaid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1611277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
