Please unmount and run xfs_repair (>= v4.3) to resolve.) If you could provide an xfs_metadump image (compressed) I can take a look at it. A metadump contains no file data, should obfuscate most metadata, and should zero out unused portions of metadata sectors. Feel free to provide it off-list for maximum privacy. I'm actually looking at something right now that may be similar, so you have good timing. Thanks, -Eric
