The only way I know of is fuser, which takes either device name or mount
point as argument:

# fuser -m /dev/mapper/mysql
/var/lib/mysql:       6694c

# ps 6694
  PID TTY      STAT   TIME COMMAND
 6694 ?        Sl     0:00 /usr/sbin/mysqld --basedir=/usr \
	--datadir=/var/lib/mysql --user=mysql \
	--pid-file=/var/run/mysqld/mysqld.pid \
	--skip-external-locking --port=3306 \
	--socket=/var/run/mysqld/mysqld.sock
