why do you use qcow2 file on top of cephfs ??????????

you should use ceph as a block device through rbd.

(performance will be awfull with qcow2 on top of cephfs)

Getting this error ever time I try to clone a VM or move its disk 



Src Disk is a ceph rbd image. I've tried using ceph rbd as the dest with the same error.
