I decided to do it while i was onsite today for that very reason! It worked no issue! Thanks.

I have a Proxmox cluster (5 host nodes) where each host nodes uses vmbr0 for network access (contents of /etc/network/interfaces includes): auto vmbr0 iface vmbr0 inet static address 10.XXX.XXX.XXX/24 gateway 10.XXX.XX.X bridge-ports eno1 bridge-stp off...

OK Yes I decided to go with VxLAN and it seems to work alot better than OVS/GRE with my implementation described here: https://forum.proxmox.com/threads/openvswitch-bridge-for-cluster-vms-across-private-network.76866/#post-342238

This seems to work beautifully! Just to feedback vxlans work beautifully! Definitely better than openvswitch (ovs) bridge with GRE tunnels! For my cluster I have configured vmbr2 in /etc/network/interfaces as you mentioned on each host: auto vmbr2 iface vmbr2 inet manual...

Since I don't have a subscription at the moment I had to do this first: Make a copy of the pve-enterprise.list file run: cd /etc/apt/sources.list.d/ run: cp pve-enterprise.list pve-no-subscription.list run: nano pve-enterprise.list and comment the line using # at the beginning, save...

Thanks a lot! This is super helpful. I've started off by removing the ovswitch bridges from my nodes and tried to install ifupdown2 but getting this error?! # apt install ifupdown2 Reading package lists... Done Building dependency tree Reading state information... Done The following...

I am trying to install ifupdown2 on my proxmox hosts but when I try to do it with apt I get the follow: # apt install ifupdown2 Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed...

Thanks. That future SDN feature looks like it will be very useful! In terms of GRE tunnels I came across the need for STP for what I wanted to do and in the Proxmox documentation that to enable RSTP using: up ovs-vsctl set bridge ${IFACE} rstp_enable=true But here...

Hi did you get anywhere with this? I'm trying to do the same thing in Proxmox with ovswitch to create failsafe communications between VMs on different pve hosts ( https://forum.proxmox.com/threads/openvswitch-bridge-for-cluster-vms-across-private-network.76866/ ) I'm new to this but I've seen...

I have set up a cluster with VMs on different host nodes: h1, h2, h3, h4 I have used a OpenVswitch bridge (vmbr2) defined on h1: auto vmbr2 iface vmbr2 inet manual ovs_type OVSBridge post-up ovs-vsctl add-port vmbr2 gre1 -- set interface gre1 type=gre options:remote_ip=''ip...

Yes the VMs share the same ZFS (2 mirrored SAS disks) pool on a Dell R630 server (hba mode), it most likely is this I suppose. The server has 2 x 12 Cores so I would doubt it's CPU? In terms of VMs on a private network (bridge) with no ports/slave I assume sending data via scp on the private...

I have a VM with a 42 GB hard disk (format raw, zfs file system) which I'd like to reduce to 32 GB. I thought I could use parted to reduce the partition on the VM first and then decrease the PVE size but I'm struggling to find a method to do this? Is there any method / documentation available?

I am testing some file transfer speeds in PVE 6.2-4. I have got two VMs on a host both using same bridge (with no ports/slave) for private network (192.168.1.X). They are both using VIRTIO network device, a zfs pool for harddisk space and have 3GB or RAM and 1 socket, 2 Core CPU. The file...

well my initial plan was to use SLURM sitting on top of Proxmox for job submission/management so I may be able to use that in some way by defining different compute node pools confined to different physical servers

When you put it like that it makes perfect sense!!! Is there any software you know of that could run on top of VMs to duplicate a program running on a VM on one physical node to a VM on on another physical node so if one goes down there is redundancy. I have a feeling this is some kind of...

See references [1] and [2] Do the following on all nodes unless stated. (a) Prepare disks (Assumes the disk is /dev/sdd) fsidk -l /dev/sdd pvcreate /dev/sdd vgcreate vg_proxmox /dev/sdd lvcreate --name lv_proxmox -l 100%vg vg_proxmox mkfs -t xfs -f -i size=512 -n size=8192 -L PROXMOX...

I created a GlusterFS cluster across 3 nodes successfully, create a VM on one node and used the GlusterFS for storage. I set the VM as HA with 1 migrate/boot. I simulated a node failure (turn off / not shutdown). The VM migrates to another node but restarts rather than continues so all CPU/RAM...

Not exactly. I have configured a 5 node PVE cluster with VMs accessible via NAT. I created ZFS storage on each PVE node (using some of the hdisks) for VM disks. I then set up VM replication from node 1 to 2, 2 to 3 ... 5 to 1 every 10 mins and using HA could get VMs to migrate and (re-)start...

Thanks. I am very impressed with Proxmox so far. If we end up using it for production I would really like my organisation to get at least a basic subscription to support the great work you guys are doing! Thanks for now.

Thank you. I'll give that a try. Are there any other storage options (https://pve.proxmox.com/wiki/Storage) which could be used for " (virtual) hyper-converged"?
