It sounds like things are badly scrambled.

The log failure is probably just the first error xfs encounters;
I imagine that after you zap the log, you'll find that everything
else is in equally bad shape.
You could _try_ an
# xfs_metadump -o /dev/whatever fs.metadump
# xfs_mdrestore fs.metadump fs.img
and then try your various metadata salvage techniques on fs.img
(recreating as necessary with another xfs_mdrestore after failure)
as practice runs, but I'm guessing that xfs_metadump will fail
in equally spectacular ways.
Unless you can get your storage somehow reassembled properly, I doubt
that there's much xfs tools can do to help you.
