high avaibility

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...

Hi I have a question about bonding and HA. I want to create a HA PVE cluster, but I am confused with the bonding and its mode. See this simplified picture. I have two switches (Mikrotik CRS317, not stackable) and multiple PVE nodes (just one signed). What should I configure to create a HA...

Proxmox version: 5.2-8/fdf39912 I'm trying to find out, which node a vm is currently routed to, so I thought this command might be useful: pvesh get /cluster/ha/resources/vm:101 However, it only sends back the following error message: Use of uninitialized value in string eq at...

Hallo zusammen, ich stelle mir die Frage ob bei 3 Nodes im Cluster, aber fehlendem Shared Storage, die HA option irgendwas bringt? Ich kann ja durch die Replication z.b. ein minimales "failover" threoretisch machen? Also alle 2min Replication wäre für meinen Anwendungsfall "ok" Daher meine...

Hi there, I'm quite new to Ceph and Proxmox. And I was wondering what the minimum requirements are for running a full high available cluster. Right now to my understanding this would be: - 3 PVE nodes. - Ceph with 6(?) OSDs And of course the redundant power/network etc. but this question is...
