SOLVED Free Space Not Recovered After Deleting Files

[demob]

After deleting at least 150GB of data my free space has not been recovered.

Below is the log entry from sickrage showing that the folder in question was deleted at 11:50

Code:

2017-05-23 11:50:33 INFO SHOWQUEUE-REMOVE-SHOW :: Deleted show folder /media/TV Shows/CSI Crime Scene Investigation

But on the screengrab below you can see that the used space has not changed.

I'm expecting to have recovered to 1TB free space, but there is still only 865GB free.

There are no hidden files/folders in the "TV Shows" directory, and even though these files were not deleted through an SMB share I have checked and the "Export Recycle Bin" option is not active.

I do not have any snapshots on this volume:

Can anybody share some light on what might have happened here? Is there anything I can try to recover the missing space?

It looks like I was just being impatient, as an hour later the free space has now appeared.

I'm a little bit surprised it took so long to process, but at least everything is working as it should.

Deletions are handled asynchronously because they can take a long time.
