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@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
