It seems you fell into the standard two-disk failure mode during
resilver. If this is really the case, it seems like your pool is lost,
because raidz works by treating each block as a single raidz stripe and
spreading it over the component devices - as a result, most of your
blocks will probably be missing some data.

You can try and retrieve as much data from the pool as possible (via
something like rsync or tar), though I'm not exactly certain how well
(or whether at all) that will work.
