# ************************ # *Description of problem: # ************************ Even auth_cluster/_service/_client_required in ceph.conf is set to *none*, there is an alert when you map images in RBD pool to localhost: # rbd map -p rbd test 2017-01-23 11:47:49.458350 7ff1cd1c1d80 -1 auth: unable to find a keyring on /etc/ceph/ceph.client.admin.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin: (2) No such file or directory # grep auth_ /etc/ceph/ceph.conf auth_cluster_required = none auth_service_required = none auth_client_required = none If RBD should not allow any hosts to map any images inside RBD pool in RADOS cluster, that message does make sense. But images are able to be mapped to localhost: # lsblk | grep rbd rbd0 252:0 0 100M 0 disk Version-Release number of selected component (if applicable): * ceph-common-10.2.3-17.el7cp.x86_64
