Phil will know much more about this than me, but I did notice that the
system thinks there should be FIVE raid drives. Is that an mdadm bug?
That would explain the failure to assemble - it thinks there's a drive
missing. And while I don't think we've had data-eating trouble,
reshaping a parity raid has caused quite a lot of grief for people over
the years ...
However, you're running a recent Ubuntu and mdadm - that should all have
been fixed by now.
