That message above looks like an unreferenced block or corrupted metadata rather than an actual file. Also, if it's part of a snapshot, you simply have to destroy the snapshot. I had a pool become corrupted due to bad memory, and all of the files were still able to be manipulated. The only time EIO popped up was on the specific block that had a checksum error.
