[ceph-users] "ceph orch" not working anymore

Hi there, I have a three node cluster with latest Ceph 18 and cephadm as orchestrator. One node is dead. So the cluster is not healthy but working. Now: Working: cephadm ls or other commands with cephadm... However: ceph orch... does not work at all: Error ENOENT: No orchestrator configured (try `ceph orch set backend`) But it is set! And disabling and enabling it does not work! The cluster is running and working. All ceph commands are working fine. ceph mgr fail or restarting the MGRs did not help. Checked the configuration: ceph config get... everything is fine. Any ideas? Best, Malte
