4 TB My Cloud full, because of 1,5 TB other files

Hi,

I’m using about 2,5 TB of my 4 TB My Cloud. I regularly check this, but now all of a sudden my My Cloud is full. And i have not added 1,5 TB of data!

I checked the dashboad and i suddenly see 1,5 TB being used by “other files”.

So i start googling, so far i’ve learned about SHH, WinSCP, putty, seeing hidden files with putty, etc, etc.

I’ve read that there are issues WDSync, but i’m not using WDSync. I can’t find hidden WDSync folders either.

So here i am, logged in with WinSCP and putty, i see a LOT of folders, but how do i find out where the 1,5 TB of “other files” are located?

So i did a little more digging.

First of all deleting files off the My Cloud does not lead to extra space. It just increases the size of the other files, i still have 0 bytes available after deleting a lot of files.

I’ve noticed that all my files are in the DataVolume folder, but also in the NFS folder.

Is this normal?

I’m not really sure i know what NFS is…

The files are in both locations. But there is only on copy of them on disk. If you do a df you will see that both the DataVolume and nfs are mounted using the same disk partition /dev/sda4. Not sure how you are getting the impression that deleting a file increases the size of other files. Deleting a file will in fact increase the free space on the disk partition. Look at the output of the df command. Then delete a file. Now look at the df command again. You should see the in use number decrease and the free space increase by the size of the file.

I have deleted a lot of files off my My Cloud, but the dashboard keeps saying it’s full. After deleting a lot of files the space used by other files has increase according to the dashboard.

Edit,
i have started putty and used the DF command.
After deleting files use% of /dev/sda4 is still 100%

To get the du command to show less than 100% you would need to remove a lot of files. If you use the du command with out the -h. You will see the values in bytes. If you delete a 1K file then the numbers should show that used decreased by 1K and free increased by 1K. You also should do a du -d1 on each of the mount points.
The df shows the inuse and free for the /dev/sd4 partition not the mount points.
Show the results of a df command and the du -d 1 for /DataVolume /CacheVolume /nfs/[Public,Audio,Foto,System,Files,Video,TV_Shows

If you will notice /DataVolume/shares contains that same folders as /nfs.
But what you could do is delete a few files and redo the du command. It should show
less space taken up.
