AFAICR, there is an undocumented location for a ceph.conf,
The config should have the following content.
rbd default data pool = ceph_pool_ec
Then rbd will use the data pool. This should probably work for all storage operations.
Newer ceph versions should also work with the config db option.
ceph config set client.xxx rbd_default_data_pool ceph_pool_ec
