Can you restart the primary MDS (not sure which one it currently is, should be visible from the mds daemon log) and see if this resolves at least temporarily? Because after we recovered the cluster and cephfs we did have output in 'ceph fs status' and I can't remember seeing these error messages. This old bug [1] describes the same issue, it seems, and it was just recently updated. Not sure though if the backport made it into latest quincy. And 'ceph mds metadata 0' also results in missing output: root@node01:~# ceph mds metadata 0 {} Error ENOENT: [1] https://tracker.ceph.com/issues/24403 Zitat von Manolis Daramas <mdaramas@motivian.com>:
The current ceph version that we use is 17.2.7.
We see in the Manager logs the below errors:
2 mgr.server handle_open ignoring open from mds.storage.node01.zjltbu v2:10.40.99.11:6800/1327026642; not ready for session (expect reconnect) 0 7faf43715700 1 mgr finish mon failed to return metadata for mds.storage.node01.zjltbu: (2) No such file or directory
and in
# ceph fs status Error EINVAL: Traceback (most recent call last): File "/usr/share/ceph/mgr/mgr_module.py", line 1759, in _handle_command return CLICommand.COMMANDS[cmd['prefix']].call(self, cmd, inbuf) File "/usr/share/ceph/mgr/mgr_module.py", line 462, in call return self.func(mgr, **kwargs) File "/usr/share/ceph/mgr/status/module.py", line 109, in handle_fs_status assert metadata AssertionError
Does anyone know what they are and what we can do to fix them ?
