Hi, I upgraded a test cluster to 15.2.11 and after the upgrade has been finished the cluster status was in HEALTH_WARN because of: AUTH_INSECURE_GLOBAL_ID_RECLAIM_ALLOWED: mons are allowing insecure global_id reclaim According to the documentation at https://docs.ceph.com/en/octopus/rados/operations/health-checks/#auth-insecu... I ran ceph config set mon auth_allow_insecure_global_id_reclaim false because no client was reporting using insecure global_ids. Now "ceph -s" cannot connect to the cluster any more: # ceph -s [errno 13] RADOS permission denied (error connecting to the cluster) What should I do?
