Hello All, I just installed ceph iscsi target following "manual installation" at https://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli-manual-install/ When the api server starts it seems to work but in service status it reports: apr 30 07:22:51 lab-ceph-01 rbd-target-api[58740]: Processing osd blacklist entries for this node apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: No OSD blacklist entries found apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: Reading the configuration object to update local LIO configuration apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: Configuration does not have an entry for this host(lab-ceph-01) - nothing to define to LIO apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: * Serving Flask app "rbd-target-api" (lazy loading) apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: * Environment: production apr 30 07:22:52 lab-ceph-01 rbd-target-api[58740]: WARNING: This is a development server.
