Hi I am sure that this has been done before, but not exactly been able to out if this is possible. We currently a fairly large 3-node cluster on PVE with PVE-managed Ceph for the storage. Due to NIS2 and other local regulations we are being forced into having "encryption at rest" for all virtual...

Hi We have recently found that our DNS provider is supported in the PVE ACME client and we did therefore configure it according to the documentation Since the provider does not yet have specific form fields configured, we simply added the environment variables (for use with acme.sh) as key-value...

Hi We are looking into rotating our fleet of servers to gain more performance with less physical space used by going from Intel Xeon Gold 6226R to AMD Epyc Genoa based systems instead. Until now we have been primarily using Intel Xeon-based nodes in our cluster, but for our workloads we get...

Hi We have now been running Proxmox VE for a while and even before Proxmox Backup Server was released. After switching to Proxmox Backup Server we have noticed that during the time where the backup of a VM is running, the Disk IO graph spikes to somewhere between 2G and 5G, which means that if...

Hi We are looking into hardening our PVE setup. Currently access to the web UI is fairly locked down with restrictive inbound firewall rules and 2FA for all users, including root@pam. We do however plan to update the SSH server configuration to disable password-based authentication entirely, so...

Hi We recently deployed a small 3-node PVE cluster on-premise. All three nodes run Ceph OSD, Ceph Monitor, Ceph Manager and Ceph MDS. We run the setup with 3 switches and each server has 4 NICs. The two first NICs are configured as a linux bond in failover mode and have a cable to each of the...

Hi We have been doing some lab testing on creating a prebuilt image of Ubuntu for various application types where things like the qemu-guest-agent is preinstalled etc. These images are based off the official ubuntu cloud-images and we therefore use cloud-init inside Proxmox to do the...

Hi We are looking into optmization of parts of our virtual infrastructure hosted on PVE. For this we have looked at the official Proxmox benchmarks for both Ceph and local ZFS pools and have noticed a very specific configuration, where OVMF BIOS was used on q35 machines type. Are the any...

Hi We have some larger virtual servers running on a ZFS mirror of nVME drives. These virtual servers run various different applications, but mostly they run Microsoft Windows Server with Microsoft SQL server on top. In terms of ressources, they have 500-900GB of disk space on a single virtual...

Hi We have experienced an issue for some time now where a VM is running extremely slow and access to disk IO is almost impossible during the backup. Usually it is not a problem as backups to PBS finish within a few hours. It is however a problem when backups take longer than usual and run ov er...

Hi We rent physical hardware in a DC for storing the PVE guest backups off-site. On this server we have installed PBS. Now our PBS server is starting to reach 80% capacity and as per the dashboard it is expected full within the next 30-40 days. All backups are running with encryption enabled So...

Hi We have now started the process of replacing some nodes in our cluster. The cluster runs Ceph + HA. What we have done so far is "out" each OSD and let the cluster rebalance after each OSD. Then stopped the OSD and deleted MGR, MON and MDS roles from the node to remove. Then we rebooted the...

Hi I have found some documentation of the case that I am facing, but wanted to run it by some of experts here first :) We currently have a 5-node PVE cluster where 4 nodes are running a Ceph cluster and with Proxmox HA configured for all VMs on these nodes. Each node has two NVMe drives each...

Hi We are in the process of migrating services from servers running a local ZFS-mirror on 4TB nVME SSD drives. We are migrating to new servers with the same specifications and hardware as what is currently running, but instead of spreading services over two nodes (a 3rd node runs some internal...

Hi We have been doing some testing on HA with PVE and Ceph, which has given very possitive results in terms of our goals with exploring the setup. From our testing, we have found two issues that we had not really expected 1. When a host has failed and comes back online, VMs are not migrated...

Hi We are looking into hardening our infrastructure to better handle outages due to network or hardware failtures. We use OVH dedicated physical servers for our infrastructure and currently have 3 node PVE cluster. This cluster is currently configured with 2x4TB nVME drives per node, with one of...

Hi For some time now, we have had a strange issue with the VM running our Zabbix monitoring server. Zabbix runs as a VM on our PVE cluster and monitors all running virtual machines on the cluster. Zabbix VM is running CentOS 7 as the guest OS. Whenever a backup of this VM is triggered, it seems...

Hi For a few years, we have been running PVE on OVH dedicated servers in Europe and changed servers as we outgrew the ones we had. At this point we have their HG-servers, where components can be changed from month to month. In preparation for a drive replacement on our servers (larger capacity...

Hi Today we provisioned a OVH dedicated server as a new node for our PVE cluster. Upon adding the node from the UI and setting the ring0 address/link0 address, we could not get the node to join. We tried to figure out why and finally got it to join. However, there is a strange difference between...

Hi I am experiencing a strange issue with 2 VMs on our 4 node proxmox cluster. The 2 VMs are on the same host. When either scheduled or manual VZDump starts, it locks the VM completely and nothing more happens, Only way to get past the problem is to stop the vzdump job and do a unlock and reset...
