Not sure I understand this fully. Does that mean you can use the IB cards and switch like you would otherwise use ethernet cards? But you can't use the switch with ethernet cards and cables directly, right? There seem to be splitter cables that connect to the SX3036 (or other IB switches) and...

So, the SX6036 I received is on 3.6.8008. This means that my switch can do QSFP56 already (I don't have the cables for that atm -- they cost an arm and a leg, so this is only theoretical), right? (The most current version I could find, seems to 3.6.8012 (which is from end of 2019). I will try...

The next issue I'm facing is that, with 10gbe, I am running 3 networks: Corosync, Ceph and backup. But with the Infiniband cards, I only have two ports per node. The first network I am going to replace is backup. But I then need to decide what to do with the other two networks. - Only switch...

One more question about the infiniband cables: There seem to be (normal) copper cables and there also seem to be fiber optical cables. Both seem to have the same plugs at the end. Can I use either copper or fiber or can I only use copper? And if I can use either, can I mix them in one switch...

Okay, so it's working again. I don't know what exactly did the trick and it might not be a solution to apply in similar situations, I'm afraid... So what did I do? Well, I have been waiting to switch from 10gbe ethernet to Infiniband for a while (I opened another thread in that respect). My...

Yes, I have not rebooted.

Fortunately, I migrated the important VMs away from the upgraded node before upgrading. So they reside now on the quorate two node part of my cluster. I think I will wait and hope that tomorrow the Proxmox guys know what to do. But thank you for your thoughts and time!!!

No dice

I checked the output of systemctl corosync.status and, among other stuff it says on the upgraded node: A new membership (4.6c7) was formed. Members joined: 4 whereas on the other nodes it says: A new membership (1.6c1) was formed. Members left: 4 Since you suggested that there might be an...

I am just now looking into pve-cluster.service with corosync.service being the next in line.

Ext4 on all of them. (I think I did install PVE on ZFS a few years ago (prior to my current cluster) and this gave me some other (booting?) issues and so I refrain from using ZFS on the boot drive.) So, unfortunately, upgrading is a one way ticket for me...

It would seem so. Unfortunately, neither is an appealing choice...

Oh, okay, at the datacenter level it is set to "no" (which makes sense as I can't remember activating the firewall).

cat /etc/pve/corosync.conf logging { debug: off to_syslog: yes } nodelist { node { name: node1 nodeid: 4 quorum_votes: 1 ring0_addr: 192.168.123.6 } node { name: node2 nodeid: 3 quorum_votes: 1 ring0_addr: 192.168.123.1 } node { name: node3...

Firewall is set to 'yes' on all three nodes but no rules have been defined.

I can also ssh from all of the nodes into all of the other nodes. So it doesn't seem to be an ssh certificate issue (if there is such a thing).

Would it make sense to upgrade also the other two nodes to PVE 8.2.2? I am a bit reluctant to try in case none of the nodes will be able to see the others anymore...

As per this thread, I have added all hosts to each host's /etc/hosts file: https://forum.proxmox.com/threads/one-node-cannot-see-other-nodes-in-a-cluster.97367/ Unfortunately, this does not solve my issue.
