[SOLVED] Cannot link nodes in Cluster

[gfngfn256]

That's exactly what I did.

That's not what your above post says. Maybe you did it after posting, (but seeing that that post was only 15 mins ago, you should apply to Guinness for world-record of shortest dual-install & update of 2 Proxmox nodes).

Yeah - you should see me typing :-D

Nah - I did this some two weeks ago without any positive result.

Look - I'm only trying to help. Bear in mind - the majority of users, install numerous PVE nodes & cluster them without any major event.
Sometimes something does go wrong, and although it is occasionally caused by HW/NW/software issues - in the majority of cases it is caused by human input/config error - that is just my experience.

So I repeat, try again & do the steps I outlined above.

Thank you for your patience!

Since two weeks, I'm repeating this process over and over again. Always getting to the same result.
What jumps out of the logs for me is the repetition of

corosync[1064]:   [TOTEM ] Retransmit List: 13 14 19 1c 1d 1f 20 21 22 23 24 33 35 36 37 38 39 3a

I just don't grasp it.
Where is this coming from? I just don't have a clue.

Did you follow my hint regarding "interfaces holding identical information" in https://forum.proxmox.com/threads/cannot-link-nodes-in-cluster.156330/post-716616 ?

You have one bridge vlan-aware and one without. I am not saying this is the source of your trouble, but it is not clean... and not usable in the final cluster if you want to be able to migrate VMs. Also we do not know which special configration the switch may have...

Building up that "Retransmit List:" is the problem and unfortunately I do not see the root cause, sorry.

Turns out it must have been an unreliable CAT Cable.
D'oh!
