high avaibility

Hi, relatively new to PVE in a Home Lab. I already have successfully set up a 3-node cluster and can manage the HA and zfs replication with no issues. Question 1: Up to having 2 nodes down due to lack of power, I am left with 1 node that can work on UPS when power is down, and in that case it...

bonjour, I am aware of the fact that local storages do not support containers/VMs with HA. But I have to restore some LXCs backups (in .tar.lzo format) in local storage from time to time and I always fail (local storages are not meant for HA enabled containers/VMs ) Is there a way to disable HA...

Just sharing a possible issue some people may run into in the future experiencing a broken pipe when migrating a VM, during a replicate operation, etc. BACKGROUND I recently upgraded the CPU and motherboard for my alternate node. There were some issues during the upgrade and considering I had...

Hello proxmox fourms! I'm recently getting this error (and the same error minus line 1 when starting without using HA) when attempting to start this container. Im a bit stressed, because the backup for this container is a bit old, and id really like to restore this container to functionality. I...

Good morning all, I have set up my Proxmox 6.2-12 nodes and enabled high availability for my VMs and containers and now I would like to test the HA functionality. I tried rebooting a node but quickly found this does not work - the VMs remain in a frozen state as the shutdown is graceful. Short...

Hi ! I hope you are okay and that COVID19 is not too restrictive for you! I want to create a new HA cluster with proxmox. My goal is to use it in production mode. I am wondering about public ip. For example : If I create a virtualized web server available on the internet with a public ip...

I am evaluating an 5 node cluster (nodeA to nodeE) where every VM is bound to run on a specific node by assigning a specific HA group I have for every node. Example: group: prefer-nodeA nodes nodeA:1 nofailback 0 restricted 0 my datacenter.cfg contains ha: shutdown_policy=migrate...

Hi all, I'm in the middle of creating my cluster and adding new nodes. I kept pve-ha-lrm and pve-ha-crm services disabled since I'm removing cables and rebooting nodes etc. I need all nodes not to fence In the middle of deployment one of my team added vms to HA resources. I need to delete...

Hello all, [Background] We recently set up our first Proxmox cluster with four new HP ProLiant DL360 Gen9 servers and a HP-2530-48G (J9775A) switch. The servers' NICs configured to form LACP bonds to the switch, and we have set up CEPH and HA in Proxmox. [Issue 1] We were getting random...

Hi, I am about to manually change the corosync config on my PVE cluster to introduce a 2ng Ring-Interface. I have read up on how to do that and although I am pretty sure, I got the config right, I was wondering if I could somehow prevent my nodes to be fenced, should I have messed up the new...

Hello everyone, I'm running into an issue with container migration that I just wanted to get some clarification on. I currently have a two node cluster that I will be adding a third node to for HA. Both nodes have the following drive config: OS: 120GB RAID 1 VM/LXC Image Storage: 500GB RAID 1...

Hello, I have 2 proxmox PVE 6 nodes in HA (softdog) at two different sites connected by internet through a VPN. I use a third computer (Synology) to keep the VM (high availability) using the NFS. The problem is that I don't want the HA process to start just for the loss of connectivity for 30...

I have CEPH and HA configured and working properly, however in testing when I shutdown a physical node the VM is migrated and rebooted what I want to understand is if this is normal behavior or if there is a way not to reboot the VM when the physical the node fails

I had a server die this past week and I removed it from the infrastructure. I can confirm that the server is out of commission and is pulled from the rack. I removed the node and all is well, or so I thought. The cluster is giving me an issue with regards to it seeming not being able to find the...

Hello, I have been running 1U Xeon e5 2620 v4 CPU with 4 Sata SSD(Adata SSD 1tb SSD, very slow for ZFS:( ) configured on ZFS mirrored stripe. It run well for me but it doesn't have enough IO for my VM needs. So I recently we purchased Amd Epyic 7351p with 8 NVME ssd (Intel P4510 1TB) to solve...

Hi, I'm running PVE cluster on 6 nodes. In total 2 different server models are used, but all are from Lenovo. In the server configuration I can define 3 types of server timeouts: OS Watchdog Loader Watchdog Enable Power Off Delay I read here that by default all hardware watchdog modules are...

I'm not sure if there is the correct site to explain this case. I want to make a firewall cluster with load balance and High Availability. I thought to use Proxmox for the cluster and make 2 nodes for the load balance and 2 more for the HA. The problem is, how can I make the load balance? I...

Hello, I'm curious to get feedback if this setup makes since or I'm looking at things from a bad angle. I currently have a Ceph cluster setup with 4 servers 11x4TB HDD's 10g for pub/priv. I'm thinking of setting up 3* proxmox servers with 1HDD for OS and 2 SSD to act as OSD's for a proxmox...

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...

Hi all, I have a 3 nodes cluster with a ceph storage (3mon, 3 OSD and a CephFS installed). I enabled the High Availability feature for my virtual machine and when I shutdown one of the nodes, my VM migrates to another and restarts. My VM is a Windows 2012 R2 server. My question is : is there a...
