Last week, i tried configuring an HA cluster with 3 computers. Everything went fine till i tested the system by pulling out one of the nodes. The VM switched over just fine but could not start. It returned me the following error: After hours of trying different sollutions, i found a fix for the...

Hi community, i have created a hyperconverged ProxMox Cloud Cluster as an experimental project. features: using 1blu.de compute nodes: 1 Euro / month using 1blu.de storage node 1 TB: 9 Euro / month using LAN based on Vodafone Cable Internet IPV6 DS-LITE (VF NetBox) the ProxMox cluster uses...

Hi there! I want to know how can i use two nodes in HA but using 3rd node only for arbiter and gluster arbiter (not for VMs). I have two powerful nodes (CPU,RAM,HDD), and one very small node Any help :)

Hi everyone, Quick and simple set of similar questions: Before restarting a CEPH OSD, should you mark it as "Out"? Before restarting a monitor, should you do anything? Before restarting a node, should you do anything? Before restarting a manager or manager node, should you do anything...

Moin, ich bin ja gerne unendlich faul und lasse die Büchse beim Neustarten die VMs selbst verschieben und neu wieder reinholen. Im Testcluster (homelab) habe ich das ähnlich wie hier: Mein Gedanke war, dass die VM ein festes Zuhause hat und bei Bedarf _random_ verteilt wird, nämlich da, wo...

Hello people, I recently did some testing for our new cluster, and came to the conclusion, that virtual machines and containers don't get migrated to another node in the cluster when the underlying storage (a local ZFS pool) dies. Is it possible to configure such thing anywhere or does the...

I have a 3 node test cluster PVE (6.4.4), identical Nodes, 4 Networks, setup as mesh network with broadcast. WebAccess Network (192.168.178.x) Card 1 1GBit/s PVE HA Network (192.168.168.x) Card 1 1GBit/s Ceph Public Network (192.158.158.x) Card 2 10GBit/s Ceph BackEnd...

Hallo, ich kann aktuell kein QDevice hinzufügen. Beim Zertifikatrequest bricht er mit folgender Fehlermeldung ab: INFO: generating cert request command 'corosync-qdevice-net-certutil -r -n hks' failed: open3: exec of corosync-qdevice-net-certutil -r -n hks failed: No such file or directory at...

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...
