[Bug 1680448] [NEW] Can't boot with degraded RAID 1

Thu Apr 6 12:28:44 UTC 2017

Public bug reported:

I just made a fresh install from ubuntu-16.04.2-server-amd64.iso,
updated all packages, and tested to boot without one disk. It failed.

See the attached screenshot for error messages.

This is probably the same bug as https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=859691

Workaround:
mdadm --run /dev/md0
[CTRL+D] (to exit initramfs shell)
