I'd try to recreate the array with a copy of the disks

do a ddrescue of the 3 good disks and then try a mdadm -C with the exact
parameters of the array creation with the same mdadm version (use missing
for slot 2).  It saved my raid10 array.

You mean you sdc and sde plus either sdb or sdd, depending on which
one I think is more sane a this point?

mdadm -E before http://pastebin.com/f46EWXEA vs after
http://pastebin.com/Kp145Mkx indicates sdb1 is missing a few events,
dunno if that's too much to be usable at this point?

Can the create-process be done "read-only", so that I don't have to
use extra disks? If I've understood things correctly --create will
only overwrite the superblocks, not touch the data?

So I could do:

mdadm -C /dev/md0 /dev/sdb1 /dev/sdc1 misssing /dev/sde1

I suppose the 33% restored spare sdf1 won't help any in this situation?
