In [2] I see Error: Could not stat device /dev/vdb - No such file or directory. /dev/vdb is the default and as per the logs it doesn't exist on your HCI node. For your HCI node you need to have a block device (usually a dedicated disk) which can be configured as an OSD and you need to pass the path to it as described in the following section of the doc. https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/ceph_config.html#configure-osd-settings-with-ceph-ansible Also, ensure your disk is factory clean or the ceph tools won't initialize it as an OSD. The easiest way to do this is to configure ironic's automatic node cleaning.
