Don't bother.  lsof isn't going to help until you could view its output
immediately before it attempts to unmount the partitions.

What you could try (prolly best from runlevel 3) is to remount the
partitions readonly.  That should effectively duplicate what the shutdown
is trying to do (flush the buffers to disk).
