Ceph Storage - Is it possible to delete manually raw files on ceph?

Hello!

I have searching a lot and i know a lot about ceph, but i cant find a solution to delete manually a raw file (disk) on the ceph storage. It is not possible on the GUI (greyed out), and i find no other way to get on the ceph storage to delete the special one unused raw disk. Does anyone know a solution?

Background: Last week i moved a disk from NFS Storage to the ceph storage, but i must abort that after a while. Next day i repeat the move disk option from NFS to ceph. That works fine, but now there are two raw images, but only one of them is used.

Thanks in advance,

Roman
