/dev/simfs is 100% busy on the VPS and du is only 50%. How to find the rest?

Question

Network administration

Greetings!
There was a problem with VPS hosting. Writes - the place is over.
Here are the outputs of some commands:

9.5G    /

[email protected]:~# du -sh /var/lib/transmission-daemon/
7.4G    /var/lib/transmission-daemon/

On the last command, I see that 7.5GB is occupied by a torrent downloader (with downloaded files). I don't use a server anymore. Therefore, I can’t understand where another 9GB has gone (2 GB, I suppose, is occupied by the operating system)?
Actually, the hoster tells me that they say I have all the space / dev / simfs occupied and these are my files. But some sites say that this generally shows the size of the disk on the physical server, i.e. not just my quota.
I am being scammed and if not, how do I find what takes up the rest of the space?

Answer 1

Look at the log folder, it may have been bombarded with errors.

Answer 2

Yes, this is a typical garbage, it is treated by the hoster somehow, kick them. Maybe the host is overselling. I had this, they gave 80GB of space, df -h showed that 56GB was occupied, although du -sh / did not count more than 2.

Answer 3

sudo du -sh /*
and then deep down
you have 20G on your disk and the user found only 9G, so another 10G is somewhere under the closed folders

Answer 4

It was the same story with a VPS on one of the hosts, I was looking for a solution on the net - try these:
# du -h --max-depth=1 /
Display information about free and occupied disk space on mounted partitions, in a format that is easy to read , tree filesystem mapping depth 1
# ls -lSr | more
Displays a listing of files and directories, sorted in ascending order of size and redirects it to the more program for paging
. By the way, my problem was solved by changing the VPS to rent a dedicator

Answer 5

This is how openvz sees itself. The host is running out of space. Write to them.
