Hello all Recently upgraded to 19.2.1 and started facing .. Invalid grafana certificate on hostnode1: Invalid certificate key: [('PEM routines', '', 'no start line’)] Tried suggest steps, even re-deployed grafana but no solution? 1. [WRN] CEPHADM_CERT_ERROR: Invalid grafana certificate on host node1: Invalid certificate key: [('PEM routines', '', 'no start line')] Detected invalid grafana certificates. Please, use the following commands: > ceph config-key set mgr/cephadm/node1/grafana_crt -i <path-to-ctr-file> > ceph config-key set mgr/cephadm/node1/grafana_key -i <path-to-key-file> to set valid key and certificate or reset their value to an empty string in case you want cephadm to generate self-signed Grafana certificates. Once done, run the following command to reconfig the daemon: > ceph orch daemon reconfig grafana.ld6-converged03n.ld6.netskrt.org Also, when I exit my host from maintenance, I get below… but when I rerun same command, it works fine, why? 2. # ceph orch host maintenance exit node2 Error EINVAL: Traceback (most recent call last): File "/usr/share/ceph/mgr/mgr_module.py", line 1862, in _handle_command return self.handle_command(inbuf, cmd) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 184, in handle_command return dispatch[cmd['prefix']].call(self, cmd, inbuf) File "/usr/share/ceph/mgr/mgr_module.py", line 499, in call return self.func(mgr, **kwargs) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 120, in <lambda> wrapper_copy = lambda *l_args, **l_kwargs: wrapper(*l_args, **l_kwargs) # noqa: E731 File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 109, in wrapper return func(*args, **kwargs) File "/usr/share/ceph/mgr/orchestrator/module.py", line 805, in _host_maintenance_exit raise_if_exception(completion) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 238, in raise_if_exception e = pickle.loads(c.serialized_exception) TypeError: __init__() missing 2 required positional arguments: 'hostname' and ‘addr' Regards Dev
