The fact that the three event counts we have are near-identical is a
good sign. The worry is that sde2 disappeared a long time ago - have you
been monitoring the system? If you ddrescue it will it give an event
count almost the same as the others? If it does, that makes me suspect a
controller issue has knocked two drives out, one of which has recovered
and the other hasn't ...

But as I can see, two drives are out on a RAID1+0 array, so the array is gone.
I think we can only hope that these two disks were on different
mirrors (but this isn't
easily readable on mdadm output, I think i've sent an email asking for
a better output
some days ago)

That's why I really really really hate anything with redundancy < 2,
like a standard RAID1+0
Only 3way mirrors or RAID6 here.
