I wasn't the only one affected, there was another list member that reported the same bug, and that putting the uuid back into grub.cfg and /etc/default/grub fixed it.That, I think is a bug. Failing a drive should zero its superblock, to force a real resync if it gets added back to the array.Do you know if there are bug tracker entries for either of these bugs? I'm interesting in following them.
Not clearing the superblock when a drive fails is something that I just ran into. This one should probably be discussed upstream.
I think I remember seeing someone reporting the array assembly bug when it's not enumerated in rd.md.uuid, but I can't find the bug right now.
