Hello

I have a problem migrating VM between 2 servers using ProxMox VE 5.1

I have a cluster of 2 nodes. I want to migrate a VM from one node (called pve3) to the other (called pve5).
I use the UI, right click, option migrate and I got this message:

Task viewer: VM 109 - Migrate (pve3 ---> pve5)
OutputStatus

I executed the ssh line with verbose option and I got this:

Host key verification failed.​

I forced this node into the cluster and I had all the kind of problems with some ssh keyalias.

It happened because I have to remove and re join pve5 host to the cluster (a HDD with the OS partition broke). I replace a HDD and reinstalled it using the same name and IP.

I used the option described in https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node and https://pve.proxmox.com/wiki/Cluster_Manager#pvecm_separate_node_without_reinstall

However, it seems that pve3 kept some SSH key somewhere and I cannot find it and remove it.

Now it interferes with the operations on the reinstalled proxmox.

How could this be fixed? I tried removing and rejoining again the node, but it did not work. Should I delete the old pve5 key on pve3 server and re join pve3 host again? Where is this key?
 
Since my cluster is composed by 2 nodes, I could delete the cluster and recreate it from scratch in case of need. Will it work?
 
Install pve5 from scratch, with different IP and hostname and add it to the cluster.

I think I will do that.

Still, reinstalling a node is kind of normal if you have lot of hosts in a proxmox cluster. It is a punishment to have to rename a host and change its IP just because the cluster refuses to re accept the host with a different SSH certificate.

Is there a way to solve it? How could a reinstalled host (OS HDD formatted and proxmox reinstalled) be re accepted in a cluster when it has new SSH credentials?
 
I reinstalled the host with a new name and a new address. Now I get other error in the host:

First I created and it got locked in:

"waiting for quorum...Connection to pve6 closed by remote host."

so I rebooted the host and retried:

root@pve6:~# pvecm add 172.17.255.4 -f

I understand that we did not pay support. We are evaluating proxmox and about to do a decision between Proxmox VE or continue with VMWare ESXi 6.

I love Proxmox but I cannot make a recommendation if I cannot join a node to a cluster by creating a cluster of 2 machines. I know there is a price difference, but the fact is that VMWare works and Proxmox does not work for us and I hate to admit I invested so much time for nothing.

Please some help.
 
The host is not working now. I go to https://pve6:8006 and it does not work.

Here are the outputs of some services. Several are broken.

I found the problem. I think there is a bug in the command pvecm

I deleted the cluster. But the cluster was not the problem. The problem happens when you use pvecm add or create in Proxmox 5.1. For example, if you execute:

pvecm add IP-ADDRESS-CLUSTER

this command invoke a ssh-copy-id without parameter -i (same pvecm create). Or they invoke something that invoke ssh-copy-id without -i.

As you know, ssh-copy-id by default (without -i) invokes ssh-add -L that (from the man page) "... Lists public key parameters of all identities currently represented by the agent...".

So, IF you open a console using your GUI AND you login to the node using ssh AND use the ssh agent AND the command "ssh-add -L" lists some certificate of yours, THEN pvecm command will copy all YOUR public keys cached in the agent in Proxmox VE cluster configuration making them available urbi et orbi. This happens when you create the cluster too.

It has several ANDs but it will happen with each Linux user normally fancy enough to use a GUI and perhaps with Mac users too.

That is a horrible leak of your/my certificates, but until now, there is not error.

There is not error, until you add a 2nd node to the cluster. In this case, the certificates leaked by pvecm command are listed again so the command will try to re-store them in the cluster again, but they are already there, so you got a nice:

unable to copy ssh ID: exit code 1

and after that you never ever will be able to add a node to the cluster again.


The workaround is to use the browser console to execute any command in PVE hosts, or type commands in a text console opened physically in the host or remove your cached certificates from ssh agent (unacceptable, because if you have them there is for a good reason).
Still, those workarounds are not good enough because console browser could be available or not and perhaps the host is physically unavailable.

So this is a bug and this is a pub ssh certificate leak of the command pvecm.

PS: Please add:

pvecm remove node
pvecm destroy cluster
 
pvecm command will copy all YOUR public keys cached in the agent in Proxmox VE cluster configuration making them available urbi et orbi.
Public keys are public (known by everyone) by design. How can public information leak?

Please show 'pvecm status' from node pve3.
 
Also, please post all three hosts files specifying on which host they are from.
 
I did not imply PVE is leaking public information in a derogatory way. But the fact that I could not add a node because those public keys.

I reinstalled pve5 and renamed to pve6 and after I was unabled to add it as pve6, I reinstalled PVE in that node and renamed pve7 with new IP.

In pve3, after I was unable to add the node as pve6, I deleted the cluster using a variant of the procedure described in https://forum.proxmox.com/threads/removing-deleting-a-created-cluster.18887/#post-154815 .

I recreated a the cluster in pve3 and when I tried to add (again) pve7 from my workstation (with ssh agent caching my public keys) I got the error:

root@pve7:~# pvecm add 172.17.255.4
unable to copy ssh ID: exit code 1​

it did not happen when I executed the same command from the text console (without public keys cached in my ssh agent or perhaps the ssh agent not running. It was a classic text console in the server without GUI).

So either the problem happened because my public keys were present in pve3 (before I deleted the cluster) or because some interaction with ssh agent.

Here is the output of 'pvecm status'. This status is from the new cluster I re created after wipe out everything previously there.

but this is now with the new cluster that works fine.

I have some files from the previous cluster:

.
├── etc
│ ├── corosync
│ │ ├── authkey
│ │ ├── corosync.conf
│ │ └── uidgid.d
│ └── pve
│ ├── nodes
│ └── priv
│ └── authorized_keys
└── var
└── lib
├── corosync
│ └── ringid_172.17.255.4
└── pve-cluster
└── config.db

and
/etc/ssh/ssh_known_hosts
/root/.ssh/known_hosts

let me know if you want them. Still I believe it is some bad interaction of pvecm with ssh agent.

Do you still have a problem now that you re-created the cluster?

It will be practically impossible to troubleshoot something that no longer exists.

No. After I recreated the cluster all my problems are gone. I am finishing a 3rd host configuration and I will add it to the cluster next week. I will try using the same procedure I used the first time with the old cluster because I still suspect there ssh agent is messing pvecm commands. I ll let you know the result. In the meantime I say we stop because I do not have logs or all the cfg files from the old cluster.
