failover

Hi, I plan to build a new proxmox ceph cluster (3 nodes). LACP 2x25 Gbps for ceph LACP 2x10 Gbps for VMs My question is related to the switches, I want mlag switches indeed. Mikrotik was my first choice due to functionalities and low budget as well. I have 2 CRS310 and have settled a very...

I'm setting up Proxmox server with pfSense as a VM to act as the main gateway/firewall. The system is in a remote location with a single ISP connection in passthrough mode providing a public IP. My concern: If the pfSense VM becomes inaccessible, I could lose remote management access to the...

Hello Guys, first let me tell you im very much surprised how good proxmox is (only used Ubuntu Server and Unraid before, but proxmox is (for me) levels above them). Hardware: Hetzner Root Server AMD 3700x 64 GB ECC RAM 2x 1TB SSD (NVME) 4x 22TB HDD What do i want: I want to install an Offsite...

Wie würdet Ihr es angehen?: Ein laufende(!) VM hat eine Netzwerkkarte (net2), die an eine Brücke "gebunden" ist (z. B. vmbr2). Jetzt hat diese Brücke ein Verbindungsproblem, z. B. geht ping 1.1.1.1 an ihr nicht mehr. Dann soll in der laufenden VM net2 nicht mehr an vmbr2, sondern an vmbr1...

Hello! I am testing out Proxmox and really like what I am seeing so far. (can't wait for the native Veeam integration) Let me preface this with I am a VMWare guy as I imagine many here are/were. I have a vision for some of our remote sites to have a domain controller that can failover as well as...

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...
