With the help of https://en.wikipedia.org/wiki/Mdadm, I found the right
commands to (re)assemble the raid arrays in the emergency console, in this
state:
mdadm --stop /dev/md0
mdadm --stop /dev/md2
mdadm --assemble /dev/md0 /dev/sda1 --run[repeated for all the arrays]
mdadm --add /dev/md0 /dev/sdb1
And wait for the synchronization to finish, before rebooting. Checking this
with:
cat /proc/mdstat
So it isn't an unrecoverable state, but still rather inconvenient. Specially if
the machine is at a co-location and you have to drive for a X amount of time to
go to the location to find out what happend and fix it...
