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.

(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?
