If you do a mount then unmount then rerun xfs-check, does it go

Did that a few times already, and the fs is getting mounted during boot anyway, but xfs_check still complains:

The fs is ~138 GB in size. I shall run a backup and then just let xfs_repair have its way. I just thought you guys might have an idea what these messages are about and why mounting the fs (Thanks, Dave) does not seem to care.
