In a Proxmox cluster I'm seeing the following error more often when I try to rollback. ``` zfs error: Insecure dependency in exec while running with -T switch at /usr/lib/x86_64-linux-gnu/perl-base/IPC/Open3.pm line 176. ``` The cluster is currently a v 8.0.4 but I did see the error with v 7...

On a Windows Server 2019 VM on a Proxmox host (7.1-11 PVE, 5.13.19-6-pve kernel) I'm having a strange problem: The upload to a new Synology DS1621+ is horribly slow (1-3 MB/s). The fun part is, as soon as I start another upload to anything else in the network both uploads become fast. The...

I just tried to update a standalone (non-cluster) Proxmox 6.4 with 2 GPUs (1080 and 2080 SUPER) which are both passed through to different VMs. Maybe worth to mention I also pass through some USB controllers directly to those VMs. The mainboard in use is a X570 AORUS Pro. I blacklist GPU drivers...

In one of my server I frequently run into failed backups on a CIFS location and since this is the case for several month now I thought I start a new thread, also there already is this old thread from another user but probably with a similar problem. What I can say for sure is that this is not a...

Unfortunately my Google skill was not high enough to get this seemingly basic question for my ceph vs ZFS decision answered: When I add new nodes with better disk performance (which is my current case as I replace a cluster server and the new one will be the first with NVMes) to the pool, would...

When I boot with my recent kernel (5.3.10) I cannot start my VM which gets a RTX 2080 SUPER passed through (I'll attach the full log with error below). Another VM which gets a GT 1030 passed through still works normal. However, when I select the previous kernel (5.0.x) from the boot menu...

I'm playing around with Proxmox 6 and PCI/GPU passthrough in a desktop PC with two graphic cards. I basically followed the Proxmox guides and some other tutorials out there. The setup also already works perfectly for both GPUs with near native performance in the VMs but unfortunately only as...

Hi, I'm thinking about using Proxmox for a SOHO VDI setup. So no Citrix/VMWare Horizon/WhatSoEver but just a hand full (~10) plain Windows VMs accessed via Windows RDP or maybe SPICE and this also only via LAN (and the office in question even has 10GbE fiber laid out). The requirement for this...

I’m running a fairly active but small budget Proxmox cluster for circa one year now. Meaning depending on the current project workload it only consists of 3-4 nodes and uses ZFS due to its replication capabilities which allow nearly HA-like failover times (5 to 10 minutes in my case) with a...

Hi, one of my projects uses a Proxmox unicast cluster at Hetzner. A few month ago Hetzner introduced vSwitches and from my first impression they work very well. Meanwhile all cluster nodes have a bridged interface on a shared vSwitch which is also already used for all VMs. On this interfaces...

I'm currently looking for a way to mount a snapshot (local ZFS storage) of a VM disk read only in another VM. My best find so far is this article about moving virtual disks: https://pve.proxmox.com/wiki/Moving_disk_image_from_one_KVM_machine_to_another . But this involves a lot of renaming...

I'd like to automate snapshotting in my zfs based small cluster where every VM has replication enabled. The schedule should also have a pruning logic. Basically https://github.com/EnterpriseVE/eve4pve-autosnap/blob/master/eve4pve-autosnap pretty much looks like what I want. However the author...

Hi there, I'm currently trying to setup a 3-host cluster in a datacenter where multicasting isn't possible (Hetzner) so after I read about UDPU in https://pve.proxmox.com/wiki/Multicast_notes and some tests locally I was fairly positive that this is going to work. However I only was possible to...
