This is not and has never been supported.
Do you mean 1) using the same erasure coded pool for both rbd and cephfs, or 2) multiple cephfs filesystem using the same erasure coded pool via ceph.dir.layout.pool="ecpool_hdd"?
1)
2)

So I guess I should use a different ec datapool for rbd and for each of the cephfs filesystems in the future, correct?
Thanks & Cheers
