Hello guys, I am planning to perform regular rbd pool off-site backup with rbd export and export-diff. I've got a small ceph firefly cluster with an active writeback cache pool made of couple of osds. I've got the following question which I hope the ceph community could answer: Will this rbd export or import operations affect the active hot data in the cache pool, thus evicting from the cache pool the real hot data used by the clients. Or does the process of rbd export/import effect only the osds and does not touch the cache pool? Many thanks Andrei
