ha cluster

I'm currently managing a Proxmox cluster with three nodes configured for high availability (HA). I've observed some behaviors regarding LXC container management and failover mechanisms, and I'd appreciate any insights or clarifications you might offer. Preventing Duplicate LXC Instances: In our...

Hello there, I want to create two separate pools in my CEPH. At the moment I have a configuration made on 4 nodes with m.2 NVMe drives as OSDs. My nodes also have SATA SSD drives which I'd like to use for 2nd pool but I don't see any option to select these OSDs, you just add them and that's it...

Hi there. I have a PX cluster built on 4 nodes, they have pretty much the same hardware spec which is 2xCPU sockets, 256GB of RAM and 3 network cards: 1x 2-ports 40Gb 1x 2-ports 10Gb 1x 4-ports 1Gb 1x 2,4TB SSD hardware RAID5 1x 2TB NVMe m.2 Because some configs are difficult to change and I...

I'm in the process of designing a new HA cluster across two locations. The two locations are connected together with multiple dark fibers and I would like to create an robust HA system that can migrate vm's between the locations. For storage I'm planning on using Ceph as I have experience with...

Hello everyone. I've tried to find a way to implement HA (High Availability) across all nodes, but I haven't found how to do it, except on NFS where I managed to. However, the issue is that when I turn off this NFS server, it makes my machines that rely on NFS unavailable. Is there a way or...

Currently, I have 2 nodes of proxmox cluster with a quorum device as Raspberry Pi ( on which I am running openmediavault as well) I created an HA group and added the CT, to test the HA I just shut the node the CT migrated to another node however they failed to start. Action Taken Removed from...

Hello. I'm new to proxmox and I'm trying to configure a High Availability Cluster with two nodes. I have some VMs in one of the servers (node 1), and, in case it gets down, I wanted them to continue operating in node 2 without losing information. Currently, I am using an external vote to...

Hello everyone, I have configured 5 Proxmox nodes to use FC multipath. The only way to achieve high availability is to mount them as LVM, but LVM does not seem to support QCOW2 format disks. I want thin disks, otherwise disk resources will be consumed quickly, but I also want HA. Is there any...

Hi guys, I've setup a HA cluster and added all the VMs. I have a question.... if I have VMs that are linked clones ... do I need to also HA the original templates? I have a shared storage for the VMs. Thanks

Hallo, ich betreibe mehrere 3 Node PVE HA Cluster (7.2-7) ohne Ceph (nur lokales ZFS mit Replication). Alle drei PVE Server sind an eine USV/UPS angeschlossen, welche bei niedrigem Batteriestand den Shutdown triggert. d.h. Alle drei Nodes werden (mehr oder weniger) Zeitversetzt...

The following scenario: Node 1 & 2 are a HA cluster. Node 1 hosts VM 1 Node 2 hosts VM 2 & VM 3 -> Node 1 crashes. VM 1 is handed over to node 2 by HA job. Is there a way to automatically shutdown VM 3 (low prio) to free resources on Node 2 for the downtime of Node 1 (duration of failover)?

Hello, We are having issues with one particular server proxmox 6.4 Proliant DL360 GEN9. Cluster fence it then, server goes down, logs being wiped off. Any suggestion how to fix, troubleshoot, its only this server that is having issues, but hardware seems to show no errors? Much appreciated. Ladi

Hello, Wanted to ask if proxmox mail getway can support 22000 mailbox? and if so, can we use HA structure in different network segment?

Hi! I have a proxmox cluster of 3 nodes, (node1, node2, node3) but 2 days ago I started to see a picture of how the cluster is losing node2. This node is active, it works, the VM continues to work on it, I have access via ssh and web. All nodes see it on the network. This problem prevents VM...

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...
