Yes - you didn't mention which version you used, but I'd definitely try 
something
current.  The bug rings a bell, maybe fixed now.

To be safe, you can always make an xfs_metadump image (use -o to not obfuscate
filenames for convenience), xfs_mdrestore that, and point repair at that fs 
image.
Then you'll see what it *would* do before you *do* do.  ;)

But yeah, depending on the damage done to the storage, you may be in trouble
that repair can't help with.  Depends on the failure, though.
