Title:
  snapshot keep in saving state backend with ceph

Status in OpenStack Image Registry and Delivery Service (Glance):
  New
Status in OpenStack Glance backend store-drivers library (glance_store):
  New

Bug description:
  I have glance backend with ceph  , nova images also run in ceph . Both
  vm creation adn glance image create works fine. However when we create
  snap shot both via horizon and via nova image-create it keeps in
  saving state even when size of pools showed correct image size as of
  parent vm.

   dpkg -l glance

  Now if we see rbd info it shows the correct size

  rbd info images/996726a5-7976-428f-8d1c-44fbc20b3b5f

  rbd image '996726a5-7976-428f-8d1c-44fbc20b3b5f':
  	size 20480 MB in 2560 objects
  	order 23 (8192 kB objects)
  	block_name_prefix: rbd_data.780581989a2f9
  	format: 2
  	features: layering

  
  Compare it with VM rbd

  rbd info  vms/a6f18d3e-6b5b-48a1-ab04-afc50665f4f1_disk
  rbd image 'a6f18d3e-6b5b-48a1-ab04-afc50665f4f1_disk':
  	size 20480 MB in 5120 objects
  	order 22 (4096 kB objects)
  	block_name_prefix: rbd_data.77fe06b8b4567
  	format: 2

  but after hour vm is keep in Image Uploading state . via nova list
  and nova image-list shows Saving state
