Hi Abhishek,
I found a patch here - https://review.opendev.org/c/openstack/glance_store/+/896447 Can I just simplay apply this patch on existing glance and see if it works or not?

Hi Satish,
Which version of openstack are you using? In bobcat (glance_store version 4.6.0) we have added a feature [1] RBD Trash to cover the issue you described.
Pre bobcat (glance_store version < 4.6.0), deletion of snapshot will fail with the issue you described.

Thanks & Best Regards,

Folks,
I have two openstack clouds and both have their own Ceph backend storage.I am trying to migrate instances from openstack A to openstack B.
- Take a snapshot from A
- Export snapshot and import to B
- Create instance on B
- Delete snapshot - (I am getting error because its in-use)
Because it has a parent reference to that volume. How do I remove the reference so it will let me delete a snapshot. Reason I am asking is because I have so many VMs to migrate and don't want glance to have 100s of entities in those snapshots.
What is the alternative here? I can try qcow2 if that is the final solution to make it clean.
