I don't want to remove cephfs_meta pool but cephfs_datapool. To be clear : I have now cephfs consisting of a cephfs_metapool and a cephfs_datapool. I want to add a new data pool cephfs_datapool2, migrate all data from cephfs_datapool to cephfs_datapool2 and then remove the original cephfs_datapool. My goal is to end with a cephfs with cephfs_meta and cephfs_datapool2 (i.e replace the original cephfs_datapool by cephfs_datapool2). But from what I've seen, there should be also some "metadata" in the cephfs_datapool (it sounds weird to me) which should remains after moving objects and prevent its deletion. F.

I still have few questions before going on. It seems that some metadata should remains on the original data pool, preventing it's deletion (http://ceph.com/geen-categorie/ceph-pool-migration/ and https://www.spinics.net/lists/ceph-users/msg41374.html). Thus does doing a cp and then a rm of the original files (instead of mv) allows to get rid of the remaining metadata in the original data pool ? Is it then possible to remove the original pool after migration (and how, because I guess that I have to define before the default location for data to the new pool) ? How snapshots are affected (do I have to remove all of them before the operation) ?
Why you need to remove cephfs_meta pool?
