I've plenty of mount errors, which you've quoted, so I think you might
be addressing somebody else. Or have I missed something? But anyway,
dmesg's tail is attached, with a timecheck from earlier in the file so
that you can exercise forensic skills in tying the times above to
those in dmesg.
But the 2-1 vote wasn't whether error messages were emitted, but
whether the system should mount an already-mounted partition onto
another mount point. I get error messages and the mount fails.
Others get no error messages (though they haven't demonstrated
the lack) and a successful mount, so currently I'm in a minority
of one.
Cheers,
David.
