vnconfig -l

That will tell you file system and inode. For example:

glacier:/opt/rainier/pkgsrc$ sudo vnconfig -l
vnd0: /opt (/dev/wd0f) inode 625836
vnd1: not in use
vnd2: not in use
vnd3: not in use

glacier:/opt/rainier/pkgsrc$ find /opt -xdev -inum 625836 2>/dev/null
/opt/home/reed/netbsd-i386.iso
