[ceph-users] is replica pool required to store metadata for EC pool?

Hi, https://docs.ceph.com/en/reef/rados/operations/erasure-code/#erasure-coding-... A replica pool is required to store metadata for EC pool? My case is RBD with OpenStack. With EC pool, the RBD image has to be created like this? rbd create --size 1G --data-pool ec_pool replicated_pool/image_name What about all other RBD operations, like snapshot, import, export, etc. Thanks!
