Dear all I am having problems when trying to deploy my initial monitors via ceph-deplyoy on centos 7 . The version of ceph I am running is ceph version 10.2.7 (50e863e0f4bc8f4b9e31156de690d765af245185). When I run ceph-deploy mon create-initial, i get the following errors ; [root@dumbo008 my-cluster]# ceph-deploy mon create-initial [ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf [ceph_deploy.cli][INFO ] Invoked (1.5.37): /usr/bin/ceph-deploy mon create-initial [ceph_deploy.cli][INFO ] ceph-deploy options: [ceph_deploy.cli][INFO ] username : None [ceph_deploy.cli][INFO ] verbose : False [ceph_deploy.cli][INFO ] overwrite_conf : False [ceph_deploy.cli][INFO ] subcommand : create-initial [ceph_deploy.cli][INFO ] quiet : False [ceph_deploy.cli][INFO ] cd_conf : <ceph_deploy.conf.cephdeploy.Conf instance at 0x27b5fc8> [ceph_deploy.cli][INFO ] cluster : ceph [ceph_deploy.cli][INFO ] func : <function mon at 0x27ad5f0> [ceph_deploy.cli][INFO ] ceph_conf : None [ceph_deploy.cli][INFO ] default_release : False [ceph_deploy.cli][INFO ] keyrings : None [ceph_deploy.mon][DEBUG ] Deploying mon, cluster ceph hosts dumbo007 dumbo008 [ceph_deploy.mon][DEBUG ] detecting platform for host dumbo007 ...
