This looks rather fishy. Are you sure you did not try any sort of manual
surgery on the backend (like moving around metadata backups)? You would
have gotten the same problem on the next mount.s3ql unmount if you had
not upgraded.
If you did something like that, you can try to get things in order by
removing the s3ql_metadata_bak* files from the storage backend, as well
as the local cached copy of the metadata (.db and .param file) and then
running S3QL 2.17's fsck. But no guarantees.
