Ha, that was your issue
RBD does not know that your space (on the filesystem level) is now free
to use
You have to trim your filesystem, see fstrim(8)

I think the command you are looking for is 'rbd du'
example
rbd du rbd/myimagename

They are 'thin provisioned' meaning if you create a 10GB rbd, it does
not use 10GB at the start. (afaik)

using ceph df i
using ceph df it looks as if RBD images can use the total free space
available of the pool it belongs to, 8.54% yet I know they are created with
a --size parameter and thats what determines the actual space. I can't
understand the difference i'm seeing, only 5T is being used but ceph df
shows 51T:
