I'm moving some files across different drives. I'm using

rsync -a --progress /mnt/disk#/media/<some folder> /mnt/disk#/media/<same folder name>

to move them around. This moves the file without any issue, and I can see that on the destination disk the disk usage has increased. I can see this from the webGui. However, the source disk does not reflect any changes. I do not have a recycle bin application of any kind.

 

 

When I execute `rsync -a --progress /mnt/disk2/media/movies/<some folder> /mnt/disk5/media/movies/<same folder name>` everything works as expected.

 

I then execute `rm -rf /mnt/disk2/media/movies/<some folder>` but do NOT see the webGui reflect the free'd up space. I have shutdown the array, executed a parity check, restarted the array, gracefully rebooted, etc. Nothing seems to get the number to change from 8.73TB to something smaller. These are 50GB+ files that are being moved.

 

I've tried using `lsof | grep deleted` but nothing is spat back out. I am not using `mv` as I am aware that this might not actually move the file from a different disk, but just change the path of it.

Executing the following increases the disk usage and appears correctly in the webGui.

cd /mnt/disk2/media
fallocate -l 10G delete.me

I then delete the file.
 

rm ./delete.me

Which then also correctly shows the file change in the webGui.

 

 

But doing rm on my existing files/folders doesn't. What gives?
 

Very interesting. I copied another movie to my home directory. I did so using the following command:

rsync -a --progres /mnt/disk2/media/movies/<movie folder> ~/backup_of_movie

This operated at a speed of about 150MB/s.

I then deleted the source directory.

rm -r /mnt/disk2/media/movies/<same movie folder>

But did not see a change in the webGui, but it was gone from the directory.

I then copied the movie BACK from my home directory to the disk2 folder, again using rsync.

The first 50% was at a speed of about 850 MB/s. These are SATA hard disks. Not SSDs of any kind. The webGui did NOT show any writes to the disks, nor did the disk usage increase. When I reached ~50% the speed then dropped down to ~80-90 MB/s and THEN the writes started.

 

Checksum of all files show they aren't corrupted. I can play them back without issue.

Looks like using Midnight Commander to delete files does it correctly. I used it to copy the same file to my home and then delete it from the disk. So how come using `rm` is giving a different behavior?
