failover

Hi, I have a 3 node Proxmox cluster in a data center setup. They are connected via public gateway to internet over 1 GBPS connection. Also these hosts are equipped with 10GBPS connection and connected to a private switch. Please see attached diagram. I am planning to configure CEPH private...

Hi, i got a question is possible to have 2 servers with proxmox running in mirror, when 1 of the servers fail the other continue without loss information Thanks, Best Regards

Hi everyone!

What is the best way to detect a cluster failover, meaning that my replicated VMs get started on another node? In /var/log/syslog I found the following maybe relevant messages, but don't know on which message to look after: May 27 17:10:22 bohr corosync[2084]: [MAIN ] Completed service...

We have a Proxmox cluster comprising two identical large machines, with 120 cores and 370+ gig of memory, and with each machine having two ZFS disk pools, Tank1 of 50TB HDD, and Tank2 of 2TB of SSD, and a third less powerful machine with just one ZFS pool, a mirrored paid of 10TB disks...

Hallo, ich betreibe mehrere 3 Node PVE HA Cluster (7.2-7) ohne Ceph (nur lokales ZFS mit Replication). Alle drei PVE Server sind an eine USV/UPS angeschlossen, welche bei niedrigem Batteriestand den Shutdown triggert. d.h. Alle drei Nodes werden (mehr oder weniger) Zeitversetzt...

The following scenario: Node 1 & 2 are a HA cluster. Node 1 hosts VM 1 Node 2 hosts VM 2 & VM 3 -> Node 1 crashes. VM 1 is handed over to node 2 by HA job. Is there a way to automatically shutdown VM 3 (low prio) to free resources on Node 2 for the downtime of Node 1 (duration of failover)?

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 ...

Hii everyone, So iv been playing about with HA on some OVH servers. It works but I need to code a script to point the VMs IP to the new node when they are moved. (I do not have access to vrack) . I'm wondering what the best way to do this is. I could write a function to query the Proxmox API...

Hi! I'm considering Proxmox for a new hosting environment. As we are going to leave a 12 node cluster with Virtuozzo. The intention is to have the hi or mid version of support agreement with Proxmox. We are going to start with 4 new nodes and the intention is to set up a cluster for...

Hi there, I just noticed that the shipped version of openvswitch (2.12.x on Proxmox VE 6.3) does not yet support specifying a primary member for an active-backup bond. Unfortunately, this means that there is no clearly defined state. Newer versions (since 2.14.x, I believe) do have that...

Hi, I would like to know if there are any possible methods of automatic failover VMs to another node in a cluster in a case of a unexpected network/power failure. My configurations are as follows: - - Both nodes are mounted with the same NFS pool - VMs are using the same NFS pool I am aware...

Hello, I have a bare metal server at OVH with several FO IPs. I'm trying to change my current configuration of Proxmox to the following: - PVE admin : 1.2.3.4 - OPNsense : 4.5.6.7 - VM1 : 4.5.6.8 - VM2 : 4.5.6.9 I also want to have a private LAN for the VMs and set up a VPN for administration...

So i have 2 servers, with proxmox 5.4 installed, with zfs disks, and configured in a cluster. They are identical. One very important thing is that i have no shared storage. So the vms run locally (as is, they have local disks.... so no live migration). So i have some vms on node1. From what i...

Hallo, aktuell haben wir 8 alte Server, die wir virtualisieren wollen. Die Idee ist, dass wir zwei Knoten haben. Auf dem einen laufen alle VMs und auf dem anderen werden die VMs repliziert. Im Falle eines Ausfalls soll die zweite Maschine die VMs starten. Hyper-V fällt für uns weg. Der Grund...

I have a cluster of 3 hosts and about 6 guests in an HA cluster. when I try to simulate a failure of one of the hosts by unplugging the ethernet nothing happens. I was expecting the guests to restart on the other nodes. after a few minutes of nothing I plug the ethernet back in and THEN the...
