There's still a reference to the mapper.

Filesystem mounts, not being tracked by file descriptors, are a common
cause of this symptom.  There's probably a tool for finding them, but
my method is to look for processes that might own the mount, or
perhaps check /proc/*/mounts.

When time is short, there's nothing like an "i'm defeated" reboot.
