Make sure you run only a non-destructive fsck. If the non-destructive
fsck shows no problem, do the following...
First run the sync command. The sync command forces all caches to be
written to their respective files.
If they're on a removeable drive, my next step after sync would be to
unmount the drive. Then physically disconnect it. Then physically
reconnect it. Then remount it. Then do your df -h.
Already did this. See my original post.
Also, if your removeable drive is some sort of SSD, you might need to
do fstrim, although I swear I remember space deleted but not yet
trimmed doesn't count in df. But I could be wrong.
Removable spinning disk.

Run fsck to make sure your disk isn't corrupted or damaged. Afterward,
your lost+found might get populated with the stuff that occupies the
space, done so in order for you to review.

I had some large files (over 200GB in total size) that I no longer
needed. So I removed them. They no longer show up in the
directory. However, df, still shows the space as being used. I
understand that if processes are still using the files they will not
be removed until the processes either release them, or are shut down
(or killed). I have tried using 'lsof -a -L1 MOUNTPOINT' to list the
open, but deleted files. It returns no files at all.
These files are on a removable drive. I can unmount the partition
and disconnect the drive, then reconnect the drive and remount the
partition, but the space still shows as being used. If the files are
still open, shouldn't 'umount' give an error?
I would rather not have to shut down the system. Is there some
other way to determine what is keeping these files open, or
otherwise preventing the space from being reclaimed?
