Datastore Images and systems Ceph erasure coding


I am trying to figure out why my datastore Images and Systems are reporting different sizes on Ceph erasure coding pool (EC_DATAPOOL value set). It’s like Images Datastore doesn’t care of the EC_Value .
Images Datastore reports datapool size
Systems Datastore reports EC-datapool size

Is there an obvious reason I am missing ?

OpenNebula 5.9.90 and Ceph Nautilus


I believe the above link have the answer.
It is stated there, ImageDS use different pool than SystemDS
