Hi,
I am currently debugging an issue with the ceph config checks.
We have some random hosts that alert
"HOSTNAME does not have an interface on any public network"
but they have. It is IPv6, static configured and, because we don't have a
cluster_network, OSDs are bound to that IP in the specific network.
I went through the netplan config and they are basically the same on all
hosts.
And after rebooting the hosts some of them resolved and some didn't.
How can I dig deeper to figure out what is going on.
Can you find some log output related to these events (docu here [1])?
All services are ceph-orch podman containers
All hosts are ubuntu 22.04 with latest HWE kernel (6.8.0-79-generic)
What version of Ceph are you running? We have ubuntu 22.04 clusters
configured exactly like this (IPv6 only), so I'm really curious. We
haven't seen this behavior yet (18.2.4).
