Hi, I will have several critical VMs running as DDNS or OpenVPN or SSH bastion servers. They are not heavy workloads but are not allowed to stop. However, my company has only one physical server for budget reasons. So, I fancy that I could set up 3 nested Proxmox as guests, to only run above...

I am aiming to get a 3 nodes proxmox cluster with 2 nodes connected to a DAS with this topology : The idea behind this configuration is to have an HA cluster and a HA storage. What I had in mind was to have a zfs pool accessible in an active/passive configuration between nodes and...

Hi All, I have two questions regarding VM's and HA on PVE clusters. 1. Is there an option to add the VM to HA on creation via the GUI, I am not seeing anything in the GUI allowing me to add HA protection when creating the VM. 2. It looks like PVE will restart a VM even if it is shut down via...

I am building a Proxmox cluster and I want to get the most HA from my hardware. For the Proxmox cluster I have 3 x R720 and 2 of them have a LSI 9200-8e connected for the common storage to a DS4246 with 2 IOM modules. I have 4 cables connecting 2 x R720 to the DS4246 as in the following schema ...

We're currently testing ZFS replication in order to use it on our production servers. I made a test cluster of 3 nested Proxmox VMs: at1, at2 and at3. Each node has a single 16GB drive with a ZFS pool. I created a VM and a container (referred to as "VMs" from now on) on at1, enabled...

Hello I am volunteer administrator for a non profit organization in France . We have received a donation of an old hardware configuration with 2 servers and a SAN appliance: 2 Serveurs IBM 7944 52G 1x Six-Core Intel Xeon E5645 2.4 GHz (12 MB cache), 1x 4 GB PC3-10600 DDR3 1333 MHz LP SDRAM...

What’s the expected behavior here? I have a 3-node cluster with dedicated physical corosync network, and a 2nd faster network for storage and networking. The corosync network is configured to failover to the fast network if interrupted. High availability is configured on guests with shared...

Hi all, I 'm new to proxmox and networking and general. I currently face a problem on my proxmox cluster. I have a Proxmox cluster with 11 nodes, all have public Ips and all comunicate internaly with 1000mbit connection. The internal ips are assigned to the nodes by a hosting provider, so I...

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...
