Space used not showing correctly

[machielr]

Hi guys

I wonder if someone can perhaps give me some info on this weird scenario.

We had a filesystem (/opt) that was @ 89% capacity.
We moved some data files (about 24G) from /opt to another filesystem called /oradata02.


however, the space was cleared from the /opt filesystem but was not "used" on the oradata02 filesystem.


the screenprint from the filesystems before and after is as follows:

Look specifically at the difference between /opt and /oradata02
