Hi All,
For a while now I've been using 'ceph fs status' to show current MDS
active servers, filesystem status, etc. I recently took down my MDS
servers and added RAM to them (one by one, so the filesystem stayed
online). After doing that with my four MDS servers (I had two active
and two standby), all looks OK, 'ceph -s' reports HEALTH_OK. But when I
do 'ceph fs status' now, I get this:
# ceph fs status
Error EINVAL: Traceback (most recent call last):
File "/usr/share/ceph/mgr/mgr_module.py", line 1811, in _handle_command
return CLICommand.COMMANDS[cmd['prefix']].call(self, cmd, inbuf)
File "/usr/share/ceph/mgr/mgr_module.py", line 474, in call
return self.func(mgr, **kwargs)
File "/usr/share/ceph/mgr/status/module.py", line 109, in
handle_fs_status
assert metadata
AssertionError
This is on ceph 18.2.1 reef. This is very odd - can anyone think of a
reason why 'ceph fs status' would stop working after taking each of the
servers down for maintenance?
The filesystem is online and working just fine however. This ceph
instance is deployed via the cephadm method on RHEL 9.3, so the
everything is containerized in podman.
Thanks again,
erich
