[ceph-users] bucket index and WAL/DB

Hello everybody. I searched in several places and I couldn't find any information about what the best bucket index and WAL / DB organization would be. I have several hosts consisting of 12 HDDs and 2 NVMes, and currently one of the NVMes serves as WAL / DB for the 10 OSDs and the other NVMe is partitioned in two, serving as 2 OSDs to serve the S3 index pool. I saw in ceph-ansible a playbook (infrastructure-playbooks / lv-create.yml) that creates a division where we have an OSD living with a journal on the same NVMe. The problem is that in lv-vars.yaml used by lv-create.yml it is said that this only applies to the filestore. Is this correct or can I use this same structure with bluestore? Thank you all, Marcelo.
