Public bug reported: Kernel shipped with Ubuntu 16.04.1 cannot recognize fakeRaid created from Ubuntu 14.04. I've tried three ways but none of them work.
1. Update 14.04.4 to 16.04.1 2. Fresh install 16.04.1 3. Update kernel to linux-images-4.4.0-34-generic only The result is that the mapper was seperated into /dev/sdb and /dev/sdc and cannot be rebuild with dmraid (said no raid disk) or mdadm (said no superblock). Something interesting is that when I reinstall Ubuntu 14.04.1 with my old CD, during the installation Ubuntu is able to recognize /dev/mapper/.... But when I do a fresh install in Ubuntu 16.04 with the CD, I get /dev/sdb and /dev/sdc The motherboard I'm using is Gigabyte X79-UP4 The fakeRaid with Marvell chipset on my motherboard shows the following information with fdisk in Ubuntu 14.04.4.
