Comment 22 for bug 1635049

It seems that this is still somehow broken with Xubuntu 17.04

I just tried mdadm within Xubuntu 17.04 in Virtualbox using the following setup:
1 virtual disk containing the OS.
2 virtual disks running as a RAID 1.
Whenever I disconnect one of the RAID disks, Xubuntu cannot boot.

I wrote the script shown here:
https://askubuntu.com/questions/789953/how-to-enable-degraded-raid1-boot-in-16-04lts
to the file /usr/share/initramfs-tools/scripts/local-top/mdadm
After that, Xubuntu can boot properly with the degraded RAID.

Is this the intended behaviour?
Thanks
