corosync

A question regarding upgrading a proxmox cluster and corosync: If I start with a simple setup, ie I don't have a separate NIC and network for the proxmox cluster and ceph, how can I upgrade that later by adding the hardware to the nodes of a cluster? I mean, /etc/pve/corosync.conf can't be...

Hi, I wanted to create a Proxmox cluster and roughly followed this ( myatus.com/p/poor-mans-proxmox-cluster/) procedure. But I fail because the second node can't join the cluster because Corosync complains. Node 1 = skuld (10.8.0.1) Node 2 = urd ( 10.8.0.2 ) root@urd:~# systemctl --stat=failed...

Hi, On a 3 nodes cluster (with HA VMs), since few days, I have Totem retransmits everyday at 06:00 (during few seconds). ... Aug 08 06:00:05 dc-prox-13 corosync[2378]: notice [TOTEM ] Retransmit List: 26c62fb Aug 08 06:00:05 dc-prox-13 corosync[2378]: [TOTEM ] Retransmit List: 26c62fb Aug 08...

I have an issue where I get the following error when trying to create a new HA resource in my cluster (Datacenter -> HA -> Resources -> Add). parse error - uncexpected '}' (500) I am sure this is my own fault - I modified corosync.conf to add a separate corosync network as backup as per the...

Hi everyone, I'm trying to add a node to a cluster, but it keeps getting stuck at "waiting for quorum..." I can get past it by doing "pvecm expected 1" on the node, but it doesn't actually add it to the cluster. journalctl -f shows this over and over again: Jun 29 01:33:40 waifu-pve...

Hello and thank you for making such a great product. I need a little bit strange configuration of Proxmox cluster: 1. I need three nodes cluster; 2. node 1 and node 2 have the same hardware configuration and are not used by now (no storage/vms). 3. node 3 is running in production with multiple...

I am having a hard time adding SOME nodes to an existing cluster. all nodes are freshly updated and running same version of proxmox-ve, as follows: # pveversion -v proxmox-ve: 5.1-42 (running kernel: 4.15.15-1-pve) pve-manager: 5.1-51 (running version: 5.1-51/96be5354) pve-kernel-4.13: 5.1-44...

I have created a new cluster with 4 nodes, the problem is that when I reboot them all of them are working, but after some minutes some of them says that are disconnected. When this happens I execute in the shell node: service corosync restart After execute this command the node is online...

Greetings! I recently had to add a host to an existing cluster. By some reason I did it using web interface, not command line. The host added, but its ring0 address is now named with its IP in contrast to the rest that have ring0 equal to the hostname. I have 2 questions so far: 1) Why it...

Hi! I have 4 nodes cluster. I want to have a quorum when two of them are offline. I tried setting auto_tie_breaker in corosync.conf and corosync-quorumtool -e 2 but both methods didin't work. How to configure that? And another question, why changing corosync.conf after creating cluster with...

Hi there, I'm currently trying to setup a 3-host cluster in a datacenter where multicasting isn't possible (Hetzner) so after I read about UDPU in https://pve.proxmox.com/wiki/Multicast_notes and some tests locally I was fairly positive that this is going to work. However I only was possible to...

Hello, we have a cluster of proxmox 5 with four nodes in unicast (IPv4) and the syslog of the four nodes is appreciating the following message: ... corosync[1491]: alert [TOTEM ] Invalid packet data ... corosync[1491]: [TOTEM ] Digest does not match ... corosync[1491]: [TOTEM ] Received message...

Hi all, Playing with Proxmox, and it's been a blast. Had a small question, is it normal for Corosync to log the following lines every 2 seconds, on all nodes ? Jan 15 02:18:09 kvm4 corosync[24830]: notice [TOTEM ] A new membership (192.168.220.20:765924) was formed. Members Jan 15 02:18:09...

hi ! im building a new test cluster with 5.1 to try all the new features. im getting "corosync: using 'ring1_addr' parameter needs a configured ring 1 interface!" while adding the first node to the cluster regardless of using hostnames or ips. what i did: installed 3 basically identical...

Good day to everyone. Can anyone tell me what mean this messages in /var/log/syslog Sep 21 10:50:01 pve dlm_controld[3181]: daemon cpg_join error retrying Sep 21 10:50:01 pve fenced[3164]: daemon cpg_join error retrying Sep 21 10:50:02 pve pmxcfs[2950]: [dcdb] notice: cpg_join retry 21250 Sep...

Howdy all, So I'm trying to get an odd question answered here that I can't seem to find. I know that Proxmox uses Corosync to create and manage a cluster which will let you use a single interface to manage multiple physical nodes, as well as handling HA and live migrations, but from everything...
