As to the original question:  The odds are poor, but not zero.  If you
read my advice to Marcin, you know that some information from your
original array is needed.  Do you have any of it?

The array size error that mount reports suggests that you are close
to correct.  I suspect the original array was created with a different
data offset from the new array.  The default for that changed around
mdadm v2.6.9.

HTH,

Phil
