Hello Marc, For add node to ceph cluster with Proxmox first I have to install Proxmox hehe, this is not the problem.
File configuration is revised and correct. I understand your words but not is problem of configuration. I can understand that cluster can have problems if any servers not configured correctly or ports in the switches not configured correctly. But this server never became in a member of cluster. I extracted a part of logfile when ceph down. A bit weeks ago, I have a problem with a port configuration and remove mtu 9216 and various hypervisors of cluster proxmox rebooted. But today the server not relationated with ceph cluster. Only have public and private ips in same network but ports not configured. ________________________________ De: Marc <m...@f1-outsourcing.eu> Enviado: miércoles, 13 de octubre de 2021 12:49 Para: Jorge JP <jorg...@outlook.es>; ceph-users@ceph.io <ceph-users@ceph.io> Asunto: RE: Cluster down > > We currently have a ceph cluster in Proxmox, with 5 ceph nodes with the > public and private network correctly configured and without problems. > The state of ceph was optimal. > > We had prepared a new server to add to the ceph cluster.

But I would say the most important part is your ceph cluster.

Just change the files manually if you did not edit one file correctly or the server reboots before you change the ip addresses you can get into all kinds of problems. > What happened when restarting the network service is that I lost access > to the cluster.

So now you know, you first have to configure networking, then ceph and then proxmox. Take your time adding a server. I guess the main reason you are in the current situation, you try to do it quick quick. > Why has this happened if the new server is not yet inside the ceph > cluster on the proxmox cluster and I don't even have the ports > configured on my switch?

Nothing should happen if you install an OS and use ip addresses in the same space as your cluster/client network.

No worries, your english is much better than my spanish ;) _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
