I checked all five nodes. All have nothing in cat /etc/pve/replication.cfg. 0 byte file on all nodes.

I'm having a hard time following the thread at this point. I seem to have only one problem but multiple places to have to look to fix it. I can ssh fine without passwords using the command line but I cannot migrate between hosts from the GUI. This means the GUI is using different keys than ssh...

This I need to make a note of. >it is critical to power off the node before removal, and make sure that it will not power on again(in the existing cluster network) >with its current configuration. I feel like I need to rebuild everything but since I cannot migrate, that's a problem. I've...

All this worked. Thank you very much for your help. And, now I know better how to remove a node correctly.

Thank you. All good now.

I had already shut down the 'p' node but on the new node, with no cluster, I still see the node in one of the files. # ls /etc/pve/nodes p pro01 # cat /etc/corosync/corosync.conf cat: /etc/corosync/corosync.conf: No such file or directory

You mention multiple places for ssh-keys which is what I've come up against. It seems once in this kind of situation, it's easier to rebuild everything and start over, especially since I don't have the knowledge yet. However, that would mean moving vms, rebuilding hosts, creating a new cluster...

Sorry for being quiet, I didn't get any notice of these replies. I'll check them now and try to respond to everything, or solve the problem :). Maybe I just need to migrate vms from the .76 host then re-install so make sure everything is clean again if you think it's only this host causing the...

Thank you very much. I'll check that link and see what I can learn from it. BTW, running those commands on the new node worked as you mentioned. Running them on the 'p' node (yes, should have named it better) never removes the other node. It's always shown in the Datacenter list. Looking at...

Now the question is. If I build a second host, create a new cluster, will I have something left over that will break doing that?

I understand that now :). Thank you for helping me. I booted the node I tried to remove. On that node (p), it cannot see any nodes or any status; root@p:~# # pvecm nodes root@p:~# # pvecm status root@p:~# # pvecm status root@p:~# # pvecm nodes root@p:~# # pvecm nodes Yet, the node remained...

I set up a temp cluster so I could migrate vms from the old host to the new host. When done, I wanted to remove the node (called p) from the cluster but I get this. # pvecm delnode p Killing node 1 unable to open file '/etc/pve/corosync.conf.new.tmp.78679' - Permission denied # pvecm status...

Hi, I hope I can respond to all of this. >Can you confirm you can log into this specific machine that has this in the log and from this very machine you can >manually SSH into pro06 without any issue from the CLI? Yes, I can ssh into all of the hosts with only one error as seen below. First...

They keys are definitely different but that's what I don't understand. I can ssh between hosts without using passwords thanks to the ssh keys but only the GUI is not allowing interconnections between hosts.

Does anyone have any thoughts on this? I've been stuck with this for well over a week. Not sure how to get things working again.

Hi, certainly. Keep in mind I've tried the suggestion shown in the GUI notices as well. This, I don't recall ever setting manually, "you have requested strict checking". 2023-11-02 08:48:36 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=pro07' root@10.0.0.76 /bin/true 2023-11-02...

I'm able to ssh between hosts but using the cluster, I cannot move vms around without getting key related errors. I've run this set of commands on first one host then all of them and no change. pvecm updatecert -f systemctl stop pve-cluster systemctl start pve-cluster I have read everything I...

Months later and this comes back to haunt me again. I'm able to log into any host, control all hosts from there but cannot migrate or do anything else that is inter-host communications. I thought this was solved, but it's back again to haunt me. I wish the devs would consider some sort of...

I know, it's an old question and I've read many many posts but nothing seems to solve the problem. I'm trying to import a win7 machine which works but then it never boots. I've tried removing as many drivers as possible, changing the controller, removing the network but the vm never boots. I've...

Actually, I used control-F5 multiple times to refresh the browser every time I did anything with the certs. So, I can only guess but it seems the reboot is what finally did the trick? If that's the case, it's too bad to even have to reboot a host, ever, unless there is something physically wrong...
