Hello, I have set up three node Ceph cluster to store VMs. It works very well. Altough I don't know whyfreeing spaces does not work. For example I create Linux VM with 500G disk. It only takes smallfraction of that space after installation. Then I create two big files let say 20G. With "ceph -w"...
