Hi, I ran those commands as usual: $ ceph orch host ls Result is as expected by hosts names and addresses. $ ceph orch ls Again, Expected result as before. Then I started to upgrade via this command: $ ceph orch upgrade start --ceph-version 15.2.6 It failed with attached logs. Please see logs.txt for detailed output. It says; orchestrator._interface.OrchestratorError: DaemonDescription: Cannot calculate service_id: daemon_id='cephfs.host-1.shsruc' hostname='host' This cluster have 2 nodes. Then I just ran same command again: $ ceph orch ls Result is NOT as expected. I got;
Error EINVAL: DaemonDescription: Cannot calculate service_id: daemon_id='cephfs.host-1.shsruc' hostname='host' (See attached logs.)
If I restart "host-1" then i can execute "ceph orch ls" command. After I start upgrade it errors again. Interestingly I only have cephfs mounted in node "host". Not "host-1". How can I fix this issue? Thanks, Gencer.
