ha cluster

Hi all, long time lurker, new poster, please be gentle! :p I've been running a single node with 8 VMs in production for the best part of 2 years now and happily, it has been rock solid. I also have a second node which I use for test VMs and I also run a Windows 10 VM which I use as my...

Hi folks, I was wondering if there is any way to perform a 'stop' mode backup at HA controlled VMs or if anyone has a sweet solution for this. Cannot execute a backup with stop mode on a HA managed and enabled Service. Use snapshot mode or disable the Service. This is the regular status...

Solved after read the manual carefully.

Hi all. I wanna ask a few questions: 1. if proxmox nodes in HA cluster must have the same specs (ram, cores). Ive read the documentation for HA but im not sure if it is implied that nodes must have the same specs. i will create a test cluster anyways this week, but would save me time if i have...

Hey Everyone, We recently had a network failure in one of our data centers. The network failure caused all of the proxmox nodes in our customer to fence themselves. They're back up an running, and the cluster shows all nodes in, but we're having the following issues: 1. HA no longer works...

We've been working on upgrading our proxmox/ceph cluster to new machines and 10G for ceph. Another system engineer was in the process of removing 2 nodes from the cluster. He followed a tutorial that suggested manually removing the old nodes from /etc/pve/nodes. This was obviously false...

I'm planning for a Proxmox cluster consisting of 3 nodes for compute and 3 different nodes for Ceph with SSD, And it's important for me to have HA but I'm concerned about possibility of starting an already running VM on different node by HA controller in case of a network issue. Does proxmox...

Hi, I'm running a single node Proxmox server as my homelab. Is it possible to disable / switch off unncessary services? What services could I switch off? pve-ha-lrm pve-ha-crm spiceproxy (don't use) corosync Probably some (all) are vital, but I'd appreciate some insights on what I could...

Hi there, we're playing around with Proxmox VE 5.4-3 for evaluation. After enabling HA for a VM, the VM cannot be migrated anymore. Task logs: Requesting HA migration for VM 118 to node pxm01 TASK OK It says nothing more, but does actually nothing. Same happens when we try it from cmdline (qm...

Hi, I recently scored a good deal on two used Fujitsu TX100 S3p servers. I seem to remember Proxmox supporting the use of a quorum disk to replace the third required node in a cluster so I wanted to set these two servers up as a HA Proxmox cluster with external iSCSI storage. However the...

Hi There, I've seen this raised a couple of years back (https://forum.proxmox.com/threads/migrate-vm-with-local-devices.17369/#post-88296) and I'm wondering what is the best / recommended method for migrating a VM (with Intel IGP passthrough enabled) from one node to another? Currently, my VM...

Good Morning, We would like to create following setup: - HA Cluster with 2 or 3 proxmox nodes. Later there should be around 50 LXC Containers running on top of it - This Cluster will only be used for LXC Container. So there are no requirements for VM usage - Required are all Features...

Hi all! I tested rrp in our test environment with ceph. Two physical separate network switches, one for cluster network (the nodes 10.10.10.0) and one for ceph network (172.16.0.0). I had the same experiences like the others described; if cluster network on one node is broken or offline, the vm...

Hello everyone, I have 3 nodes in cluster. h1, h3, h6 Virtual Environment 5.4-5 All Vm are in a shared resource that all nodes access. A few days ago the node h1 was restarted but never returned. Wait for vm to be passed to the other nodes but that did not happen. The node h1 retained the vm...

I have troubles with upgrade to PVE 5.4, it launches /bin/systemd-tty-ask-password-agent --watch on several occasions and hangs forever. It happens when configuring pve-ha-manager and pve-manager packages. Freeze during pve-ha-manager is especially painful as it leads to unwanted reboot when HA...

I'm trying to add some HA config to my cluster, but the HA tab is locked due to an error saying: "unable to read file '/etc/pve/nodes/dog/lrm_status' (500)" "dog" is an old node which I have since removed. Any idea where I need to remove some config in order for PVE to not look for this config...

I am trying to setup the best minimum scalable HA setup and Configuration. I read the documentation on High Availability, however I have some questions that are not well discussed in the documentation. I was thinking of starting with 4 servers: 2 x front end server that will use a central...

Hello Community, after backing up (proxmox backup function) about 120VMs in a 4-Node-Cluster via NFS, a few (~20)VMs shows the HA in error state. The affected VMs still running fine and there was no trouble at all while running the backup. All VMs are managed by HA. Here are the notifications...

Hi, I am curious to ask if anyone can comment. I'm looking at setting up for a client, a modest sized Proxmox cluster. It will be running on OVH hosted environment, ie, we have access to various pre-configured server builds and my goal is to get a config which optimizes (monthly spend, features...

Building a small home lab HA Proxmox/Ceph cluster with 3 Dell 210ii boxes. I'm trying to do it on the cheap and have decided to forego a 10Gb ring in favor of LACP'd 1Gb based network with quad port intel cards in each of the three boxes and an HP 1810G-24 switch. Due to ignorance I was...
