There might be. Try umount -f
The information about current mounts is recorded in /etc/mtab
(basically an old relic, but sadly still not put down). The real
(kernel) information about mounts is in /proc/mounts. When copying root
filesystems or working on a read-only / the mtab file can easily
contain stale information.
If you really know what you're doing, simply remove the file (protip:
after cloning /, always remove /etc/mtab from the clone), or
copy /proc/mounts over it.
