Hi all, i have a 3 node cluster. In my HA section i created a group with all nodes and i added my VMs as resources (in this case VMID 200). If i shutdown the VMID 200 from console/ssh (using "shutdown -h now" or "poweroff") or using "shutdown" from PVE GUI, the VM goes down but after a second HA...

Hi What is the best way to manage two (or more) "independent" PVE servers in the same frontend? I don't need any high availability, automatic failover or shared/synced storage. If one server goes done, then it should have no influence on the others (I should still be able to start/stop VMs...

Hello, I'm a beginner in proxmox so maybe I'm doing something wrong or misunderstood. I have a problem with 2xnodes Fujitsu RX300 S7 with connected 2x Fibre Channel to each node by Emulex Lightpulse to storage Eternus DX90 S2. I want to do HA cluster - I have on other machine - Dell R620...

Hello guys, I would like to setup a Proxmox HA cluster and as for now, I see multiple approaches for making the VM's accessible when moved to a different node. For example, having a 3 node Proxmox cluster. Each PVE node has its own public static IP address. The machines will be running inside a...

Hi all, I would like to upgrade my pve cluster from 2 nodes + qdevice and qnap shared storage to a 3 nodes cluster with ceph - what are the requirements to have 3/4 tb of storage for the vm? - are 10gb network cards enough for ceph traffic? - are there favorite models of ssd for ceph? -...

Hallo allerseits, ich hätte eine Frage: angenommen ich habe ein Proxmox Cluster mit jeweils 128GB RAM á 3 Server. Auf node1 läuft ein Server, welcher 96GB RAM zugewiesen hat. Auf node2 und node3 sind jeweils nur 50GB RAM zur freien Nutzung verfügbar. Fällt nun node1 aus sollte die HA Gruppe ja...

Hi Everyone, We've been struggling moving away from a mal-performing CEPH cluster at a customer site for a little while now, however, our NAS supports iSCSI and NFS, but not CEPH or ZFS over iSCSI. Is there truly no solution to include HA, Live Migration, and PBS Live Backups using an iSCSI...

Hey all, I deployed two servers in a cluster previously and how finished deploying 3rd for HA and having some issues with getting replication working on all three. it seems to be ssh key and hosts related, then dug deeper and likely to do with my host names being wrong. Currently 3 servers are...

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...
