OK, then probably you already confirmed these. - the error was returned by rename(2) in mv(1). - the destination /mnt/bulk-storage is not busy either. (again there are several reasons to make it busy) - any security modules don't bother you. - if there are several namespaces on your system, none of them are using these dirs. > The suspicious refcnt is all I have to go on and currently the only > difference I can see between being able to move the directory and not.

It should. I'd suggest you to try this. 0. aufs is not loaded, confirm it by "lsmod" or something. 1. "modprobe aufs", confirm its refcount is zero. 2. unload aufs, confirm again. 3. repeat the step 1. 4. mount aufs, confirm its refcount is one. 5. umount aufs, confirm its refcount is zero. 6. unload aufs, confirm again.
