mdadm: CREATE group disk not found Incrementally started RAID arrays. Incrementally starting RAID arrays...

mdadm won't boot in Ubuntu/Mint/Debian anymore.

You just get the following in a loop:

mdadm: CREATE group disk not found

Incrementally started RAID arrays.

Incrementally starting RAID arrays...

mdadm: CREATE group disk not found

Incrementally started RAID arrays.

Incrementally starting RAID arrays...

mdadm: CREATE group disk not found

Incrementally started RAID arrays.

Solution

In Linux Mint 17.2 which is based on Ubuntu/Debian the issue was I am using the 3.0 Kernel, but I upgraded the kernel to a 4.4.

Simply "hold shift" before the grub boot screen and boot your old 3.0 kernel and remove the 4.4 to boot again.

There is definitely some bug or incompatibility that was introduced, it may be in the initramfs etc.. but this is a quick fix in case you can't boot.
