Hello, dear forum users.
I installed ceph in k8s using rook for testing purposes.
Everything went up fine.
Then I created a cephfs pool for my app.
Then I deleted the app from k8s and cephfs pool and its metadata.
Now there are no pools in ceph.
But ceph tells me that "raw storage" use 0.56% space.
I don't quite understand what this data is and how to remove it.
Could you explain the situation?
Exactly what is this data for, that is assigned to a place?
How can I remove them to clear the space?
I would be very grateful for your advice.
Thank's in advance.
Below is the ceph df detail command info.
```
