    [SOLVED] section 'device' already exists and not marked as array! (500)

    Hi, I built 2 weeks ago a cluster with HA using 2 Proxmox servers. Servers version is 8.1.4 on both I made few changes to get the Quorum with only 1 server. I have 3 different networks on each : - One for storage - One for the cluster - One for the Prod They can reach each others on the 3...

    Suggesting a patch for pvecm? (adding qdevice when nodes are odd, but votes are even)

    Hi all, First off: I'm new to proxmox, and I only use this is a "homelab" setting. Proxmox (the software), this forum and it's members is a true gem, so big thanks all around! I just finished setting up a cluster with 3 nodes, where 2 of the nodes are expected to be on and off intermittently...

    Creating cluster with 5 nodes where many containers/VMs have same VMID/CTID

    Hello. I have 5 separate nodes running now and I'm planning to create 1 cluster for all of them. However, they each have VM/CT IDs starting at "100". Will this present a problem, as far as ID conflicts, or will pvecm resolve these automagically? If I have to change IDs on the 4 nodes I wish to...

    Cluster join problem

    I think there is a problem with pvecm since it can't seem to join a cluster that uses the secondary nic and IPv6 only. All the nodes are listed on /etc/hosts file and all the nodes can ping each other and echo using IPv6 (using both hostname and IP). But still every time I try to add a node to...

    Setting-up qdevice fails

    I'm trying to add an external quorum server (Qnetd) to my 2-node cluster to allow for safe HA operation. The cluster itself is setup, each nodes sees the other, migrations work, backup and restore works, etc. I simply installed corosync-qnetd on a 3rd box (fresh debian 10), without errors...

    PVE quorum on cluster

    Hi, Basically what I want to achieve is having 2 node cluster with offsite backups for redundancy. In case of node 1 failing, I will restore backups on node 2 and proceed using it. The problem is Quorum on node 2 when node 1 is dead - node 2 does not have a quorum and therefore cannot start...

    Kein Node in der Liste (Webinterface) beim CT/VM-Erstellen

    Guten Tag, erstmal ich bin neu hier, und bin noch nicht so erfahren, was Proxmox angeht :) Ich habe ein Problem bei der Liste von Nodes beim erstellen von CT/VMs. Generell scheint es, als ob keine Nodes mehr in den Auswahllisten "erkannt" werden. Der Node in der Sidebar verhält sich normal...

    pve-cluster (5.0-34) New Features

    I noticed that there's a new feature under the pvecm command to add a qdevice. I have been using Proxmox at home and for clients in a single node local storage configuration for almost a year now, and have been dying to mess with a proper shared storage/two node HA setup. My dream setup would be...

    pvecm firewall issues - no multicast

    Is there a way to configure the pvecm without using multicast? Is there a way using pvecm create cluster to force to use the internal, and not the public IP Address? We have proxmox nodes which own a public IP Address which automatically is used for cluster-management. I was able to run a...

    Can't add node to cluster

    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...
