Hi I am having this exact same problem, for more than a week. I have not found a way to do this either. Any help would be appreciated. Basically all of our guests are now down, even though they are not in production, we would still need to get the data out of them.

Kaygorodov Sent: 12. toukokuuta 2015 20:41 To: ceph-users Subject: RBD images -- parent snapshot missing (help!) Hi! I have an RBD image (in pool "volumes"), made by openstack from parent image (in pool "images"). Recently, I have tried to decrease number of PG-s, to avoid new Hammer warning. I have copied pool "images" to another pool, deleted original pool and renamed new pool to "images". Ceph allowed me to do this without any warning. But, after a some time my VM-s was stopped and cannot be started again, because they cannot open volumes, which had parent snapshots on "images" pool. I have an original image unchanged, I can made a snapshot if it was not copied by "radios cppool", but RBD images linked to parent snapshot on pool with old ID, now this pool has new ID. So, I need to change the link to parent snapshot for RBD images, or change pool id of "images" to old one. How to do this? Help, please!
