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)
rgysi cephfs filesystem

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
