I just did a clean install of ubuntu 20.04 on my system (I used to have 16.04).
My system has 4 harddrives:
/dev/sdb contains the system software (/boot and /).
/dev/sda contains the home directory of the only user.
/dev/md0 is a raid, with physical drives /dev/sdc and /dev/sdd.
I can no longer mount the raid device. Where is the information stored that tells the OS that /dev/sdc and /dev/sdd are a raid?
Since installation, I booted from a clone of /dev/sdb before the upgrade, and the raid mounts properly.
