Howdy all. What works: - I've setup Gotify and can receive messages using the "Test" button. - I get messages when I backup manually and set the "Notification Mode" to "Notification System". What I want: - I would like to get messages on events like: VM is rebooting, VM is shutdown, VM is...

I am using a pacemaker to create a cluster of 3 VMs. Is there a way to initiate a VM reboot automatically when the VM in the cluster fails in the pacemaker. I am not sure, but it looks like it is possible to use fencing. What are the steps to achieve this in Proxmox?

Hello all, we are facing a strange issue. We have a two node Cluster plus QDevice on the latest PVE version with HA enabled on the VMs. We are currently in the process of testing the cluster. In order to test the fencing and HA recovery, we pulled the network from one of the two nodes (Node 1)...

I have a 28 node PVE cluster running PVE 7.4-16. All nodes are Dell R640/R650 servers with 1.5 or 2TB of RAM and Intel Xeon Gold CPU's. They all have 2 x 1GB NIC's and 4 x 25 GB NIC's. We are connected to an external CEPH cluster. Node network config: 1 x 1GB NIC is used for...

Guten Morgen zusammen, wir hatten letzte Woche einen sehr seltsamen Fall. Wir betreiben seit mehreren Jahren ein 10 Node PVE Cluster (inkl. CEPH) und hatten bis jetzt noch nie nennenswerte Probleme. Das Cluster läuft extrem stabil und wir sind sehr zufrieden. Aber: Wir haben letzte Woche das...

Hi all Just some info about our environment: * Proxmox 7.4-3 Enterprise * 4 nodes in 1 cluster - * 1 dedicated for GPU workloads and as "extra resource when patching etc." * 3 others for all other workloads. * Each of the three are running with a 256 x AMD EPYC 7742 64-Core Processor...

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...

Hallo Forum, hoffe es kann mir jemand helfen. Ich suche Infos zum Thema fencing. - Ist das Software fencing ausreichend? - ist fencing via ILO möglich / sinnvoll? - Ich lese von den fence_tools. bei mir gibt es die nicht. - alle Infos zum Thema fenecing sind uralt (Proxmox 2 / 3 / 4) Wie...

Hi folks I have added a new node to my cluster today, then I realized the new node's network configuration might have an issue that it cannot communicate with the CEPH IP ranges, I have restarted the network service using "systemctl restart networking" after this, the disaster happened and I...

We have recently added a new node in our already existing cluster. Recently while moving a VM to the new node, the server failed unexpectedly. Since then, every time the server get started it get rebooted after a couple of minute. This prevent us to investigate and fix the problem on the node...

Hi all, Today, I rebooted one node and every node of cluster rebooted... Now, the details: I have a cluster of 4 nodes, where 1 is constantly down, because it has a hardware failure and we are waiting for spare parts. So, the cluster has 4 nodes, where 3 of them are alive. Now, I rebooted one...

We are currently running tests on a new three node HA cluster configured with 2x10G networking and shared (Ceph) storage. We are using the latest stable packages for Proxmox 5.3. The behaviour around reboots of servers is nowhere near as smooth as we would like. These are the issues that we...

Hallo, wir betreiben ein HA-Cluster mit 6 Nodes produktiv. Alle paar Monate wird ohne "erkenntlichen" Grund ein Knoten neu rebootet mit folgender nachträglicher Meldung "fencing: acknowledged - got agent lock for node" . Sämtliche Logdateien sind unfaufälig. Da ein Reboot immer mit Ausfällen...

I'm trying to run two node cluster for the first time. I'm using Proxmox latest version which is 5.1. Now I'm stuck at the fencing part. the guides says that I have to edit the following file but it does not exist on either of my nodes. nano /etc/default/redhat-cluster-pve there is no any...

Ich finde zu Proxmox 5 keine vernünftige Anleitung wie ich das mit fencing mache welches für HA eine Voraussetzung sein soll. Mir kommt das so vor als wenn ich per hand wie mit ceph noch was nachinstallieren muss. ich habe die datei /etc/init.d/pve-cluster abgeändert. dort den Eintrag...

Hello everyone, I build a Proxmox 3.4 two node cluster with two Dell R210 and a third node as iscsiTarget. This works still great. I use IDRAC for fencing and DRBD as storage. But after a powerfailure of node1, node2 tries to fence node1 with IDRAC. But IDRAC doesn't really work without power...

Dear colleagues, I moved to Proxmox 5 in a dev environment and was wondering how to setup the hardware watchdog. On the same hardware running Proxmox 4, a kernel module ipmi_watchdog has been loaded. Now I can only find the following modules. lsmod |grep ipmi ipmi_ssif 24576 0...

We are trying to build HA cluster with iSCSI storage over dedicated network interface. Looks like disconnecting storage network (in any way - physical fault or misconfiguration) doent lead to any reaction from PVE HA. For example, if node connection to iscsi storage failed, we got messages like...

I came from Vmware and have been happy with Proxmox the one dark spot is it seems like my cluster is doing false fences. Where it just takes down a node randomly and fences the VM. Also if I take down one node manually it seems to restart all of my nodes which doesn't make any sense. I check the...
