Thank you Ernesto. Yes - so I see that all the eno1, eno2, and docker0 interfaces show up with an MTU of 1500 which is correct, but since these interfaces are not being used at all, they shouldn’t be flagged as a problem. I’ll just ignore the errors for now, but would be good to have a way to

Thanks, Kai! We moved the Dashboard tickets to a separate subproject. I just moved that tracker. It should be easy to remove at least the NICs down. Kind Regards, Ernesto On Fri, Aug 6, 2021 at 9:13 AM Kai Stian Olstad wrote: > On 04.08.2021 20:31, Ernesto Puerta wrote: > > Could you please

Yes - you’re right. It’s complaining about eno1 and eno2 which I’m not using. I’ll change those and it will probably make the error go away. I’m guessing something changed between 16.2.4 and 16.2.5 because I didn’t start seeing this error until after the upgrade. -Paul > On Aug 4, 2021, at

I’m seeing the same issue. I’m not familiar with where to access the “Prometheus UI”. Can you point me to some instructions on how to do this and I’ll gladly collect the output of that command. FWIW, here are the interfaces on my machine: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group

Hi J-P, Could you please go to the Prometheus UI and share the output of the following query "node_network_mtu_bytes"? That'd be useful to understand the issue. If you can open a tracker issue here: https://tracker.ceph.com/projects/dashboard/issues/new ? In the meantime you should be able to
