Hi I am going to migrate from proxmox6 to proxmox8.1 by installing a new cluster and re-provision all my lxc servers and Kvms in a kind-of blue/green upgrade. I am using ansible to create lxc and KVM so provision is simple and fast (well, not so fast, but it is automatic) , but I am not finding...

Hi, just writing this in case it helps anyone else. Suddenly all the lxc containers of a node in a cluster failed to start, the only clues were as follows root@proxmox-2:/var/log# pct start 129 setup_resource_limits: 2517 Unknown resource lxc_spawn: 1813 Failed to setup resource limits...

I have a 9 node production cluster based on pve6 (pve-manager/6.4-13/9f411e79 (running kernel: 5.4.143-1-pve)). The older server in the cluster have been up & running 563 days while the newest is 201 days so far. 2 days ago all servers in the cluster become grayed out, but I was able to access...

Hi I am writing this here in case it can help someone else or, worst case scenario, a future me. I have a 5 node cluster (pve6) with two corosync rings to avoid losing nodes or the cluster due to network issues, so it came as a total surprise that one of the nodes suddenly appeared as greyed...

Hi I have an existing proxmox 6.4 node with containers and vms which I have converted to a cluster to add a new node. This original node is using local-lvm thin for the guests (so basically I have local and local-lvm storages). The new node is having ZFS storage, one single raidz1, and I see on...

Hi i am planning to migrate a virtual server from VM to LXC on my production cluster. This VM is currently having about 30K active tcp connections on peaktime which is no big issue for a vm, but, is there any specific recommendations or concerns for LXC guest or Node host in order to deal with...

Hi all I have a 3 node-cluster for my development environment, all three nodes are basically same hardware. Cluster is pve6 and all lxc containers are centos7. In one of the nodes, all the containers have 0 swap memory, no matter what the configured amount is for any lxc. The main node las 16GB...

Hi I have a 3 node cluster as development environment; all the nodes are basically 200GB RAM, 48 cores dell R620. I have found recently that in one of the nodes, OOM is killing always the same daemon running inside an lxc container and also a VM. The host has a lot of empty ram, taking a...

Hi i am going to deploy proxysql in my Proxmox cluster, it will be done using KVM and not lxc in order to be able to use VRRP to get H/A between several VMS in different nodes of the cluster. Is there any recommendation to the VM hardware setup, the Proxmox node itself or the VM configuration...

Hi I have a 2 node cluster with pve6.2, it is working ok, both nodes are showing the green tick and i can connect to both via ssh or via webUI. Nodes can see each other in the networking. In one node all LXC containers are showing a question mark under a grey circle. However the containers are...

Hi there I have a LXC container which uses last access time to implement sort of LRU image cache; images not accessed in X days are automatically deleted. I have cloned the container, moved into another PMX node, shutdown the original one, and start the cloned container in the PMX, but the...

Hi all As per my previous post, i have deployed a 2 node cluster (will become 3 as soon as possible), where each of the nodes is connected to two switches in a nested bonding configuration: https://forum.proxmox.com/threads/bonding-lag-with-multiple-switches.48398/#post-279823 Simply put Bond0...

Hi I have just installed 2 proxmox nodes, applied the license and configure the network as nested bonding in my production environment. The network is up and from any of the two nodes i can ping internet and ping other hosts in the network. I can also ping any of the proxmox nodes from other...
