After copying to cephfs:
root@backup-server:/mnt# du cephfs/Win2003-002-198-bak_5-flat.vmdk -h 30G cephfs/Win2003-002-198-bak_5-flat.vmdk
How did you copy that file? cp tries to detect a sparse file but may have failed here. Try "cp --sparse=always /mnt/rbd/Win2003-002-198-bak/Win2003-002-198-bak_5-flat.vmdk /mnt/cephfs/Win2003-002-198-bak_5-flat.vmdk". AFAIK this has nothing to do with CephFS as filesystems do not automagically "thin provision" files.
