Hi all, We are running a ceph cluster with filesystem that contains 5 servers. Ceph version: 19.2.0 squid If I run: ceph osd status when all hosts are online and in the output is the way it should and it prints status for all osds. If just a couple of osds are down status is printed and specific osds are stated as down. One of the servers went down and we ended up with a health warning. If I run: ceph osd stat I get the information that 64 out of 80 osd is in. If I try to run: ceph osd status I get an python error: Error EINVAL: Traceback (most recent call last): File "/usr/share/ceph/mgr/mgr_module.py", line 1864, in _handle_command return CLICommand.COMMANDS[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/status/module.py", line 337, in handle_osd_status assert metadata AssertionError I suppose this is some type of bug when one host is down? Thanks! Marcus
