Hi Ben, Thank you for getting back.
According to this documentation [1] and the osds.yml [2] from the stable branches (3.x) , it appears that Ceph-Ansible is able to create separate partitions on different devices for the non-collocated scenario for both Filestore and Bluestore. The problem is that I could not find where to set the size for the WAL and DB partitions on the journal device. As per the Ceph documentation [3], the DB partition size should be no less than 4% of the underlying OSD capacity. I do not know how to take that aspect into configuration for Ceph-Ansible.
