Hello Dominik, rpool does not have a data dataset. It was a clean install over debian, and all commands are provided in my post. I have access to the system this afternoon, then I will provide the zfs list output. Did I miss a command while creation?

I know, this is always possible. But is there any way, having booted it into a rescue system and having access to the disks? I ask, as /etc/pve is mounted via fuse, which is not available in rescue system.

Do you have a solution for https://forum.proxmox.com/threads/pvecm-addnode-via-ssh.47596/#post-224904 ? And how can I send you a PM? I tried to join the cluster members over the vlan interface of hetzner....

Having enabled via Datacenter>Firewall>Options Firewall enable did drop me out. How can I change the /etc/pve/firewall/cluster.fw hence I do not have any access to my host now. Any hints are welcome.

Perfect :) Thank you!

Looking around the installation, we find references to rpool/data. But creating the pool using commandline causes an error.... I did /sbin/zpool create -f -o ashift=12 rpool mirror /dev/sda4 /dev/sdb4 pvesm add zfspool pve$(hostname -s)-data -pool rpool/data pvesm set pve$(hostname -s)-data...

Hello, is there the possibility to add the Certificate for the hostname of the proxmox host via commandline? Currently we manage it using Host > System > Certificates and upload/paste key + fullchain. Thanks for your help in advance!

Hello, any ideas on this?

Do you have any ideas what is going wrong?

And as you can see, the pvecm create was done on vm20, and the pvecm add was initiated on vm92.

I tried following approach which did result in the weird message, as the vm20 is added to cluster, and not the new node vm92. So while vm92 is performing the waiting for quorum, I added on the vm20 (master) the config stanza for the qnetd. root@vm20 ~ # cat /etc/corosync/corosync.conf logging {...

Oh, now I see the problem. While using the pvecm add command, the vm20's corosync.conf is being replaced! There is no information about the qnetd device and my former config any more. Is this a bug, or what were we doing wrong? Best regards Thomas

Hello Wolfgang, I do not run it on a cluster member. But I did not reference the vm20 (which created the cluster above). pvecm add vm20 -ring0_addr 10.40.20.20 -use_ssh Now I end up in The authenticity of host 'vm20 (10.40.20.20)' can't be established. ECDSA key fingerprint is...

Now go to the next node, as vm92 should be added to the cluster root@vm92 ~ # pvecm status Corosync config '/etc/pve/corosync.conf' does not exist - is this node part of a cluster? Cannot initialize CMAP service root@vm92 ~ # time pvecm add vm92 -ring0_addr 10.40.20.92 Please enter superuser...

So, from the beginning: omping -c 10000 -i 0.001 -F -q 10.40.20.84 10.40.20.92 10.40.20.20 works: 10.40.20.84 : unicast, xmt/rcv/%loss = 10000/9998/0%, min/avg/max/std-dev = 2.724/2.770/2.920/0.032 10.40.20.84 : multicast, xmt/rcv/%loss = 10000/9998/0%, min/avg/max/std-dev =...

Still the question, is there any way to add cluster nodes manually? It is really hard to see that pvecm add compromizes the master node, as the new node requires a quorum... is there any way to add and get the new node arbitrating ?

We have now 10.40.20.92 : unicast, xmt/rcv/%loss = 9309/9309/0%, min/avg/max/std-dev = 0.214/0.254/0.417/0.023 10.40.20.92 : multicast, xmt/rcv/%loss = 9309/9309/0%, min/avg/max/std-dev = 0.232/0.290/0.465/0.023 10.40.20.20 : unicast, xmt/rcv/%loss = 10000/9999/0%, min/avg/max/std-dev =...

pvecm nodes only shows the local node, root@vm20 ~ # pvecm nodes Membership information ---------------------- Nodeid Votes Name 1 1 10.40.20.20 (local) root@vm84 ~ # pvecm nodes Membership information ---------------------- Nodeid Votes Name 2...

What does the parameter "votes" do? And, I use use_ssh, as I always get an error 500 when trying it with the API.

/etc/hosts and /etc/hostname are not identical. I have in /etc/hosts 10.40.20.20 v20-int 10.40.20.84 v84-int # and external, official IP 5.9.20.20 v20 188.9.20.84 v84 hostname matches on name of official IP. Do you have any ideas how to solve?
