  • Cinder supports creating new volumes from the source volume, which is known as volume cloning.
  • Cinder supports two types of cloning – full clone and copy-on-write clone.
  • Full clone copies all content from source volume to new volume.
  • Copy-on-write clone only create a link to source volume, only changed content is saved for new volume.
  • By default, cinder does copy-on-write clone until the clone depth exceed rbd_max_clone_depth.
  • Ursula sets rbd_max_clone_depth = 5 by default. It could be set to zero to enable full clone if customer requests.
