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!
