Problem with full VAR folder

Hi,

I do have a strange problem with my ESXi 6.7 server.

I tried creating a virtual machine, and I get the following error message:

"A general system error occurred: Failed to write header to "/var/log/vmware/journal/1566910456.2: Error while writing to file. There is no space left on the device"

So I checked the space on the ESXi server and with VDF command I see the following:

So the VAR folder is indeed full but I removed some files and this is still not changing.

If I run the command stat -f / I see the following:

It does seem to me that there is free space but where is it?

Tried deleting log files and is not changing a bit.

What is this issue?

Kind regards,
