  1. Epyc Zen 2 with Proxmox 5.4-13

    Hi all, I was wondering if there are any compatibility issues with Proxmox 5.4-13 (kernel 4.15.18-20-pve) and the new Zen 2 architecture with the EPYC lineup. Specifically the new EPYC 7402P. Is somebody already using such a setup, and if so, are there any other issues? Regards, Andy
  2. error with cfs lock on zfs filesystem because of timout

    Hi @all, I am facing actually a problem where I am not able to create a iscis-zfs disk because the "cfs lock" gets an timeout. The problem that "zfs list" takes very long on my iscis server, because it has a lot of writes. Is it possible somehow to higher this wait-time so that we get no...

  6. [SOLVED] VM shutdown restults in timeout

    Hi everyone, I have a problem with VM shutdowns, specificaly Windows Server 2016 VMs. When I use the shutdown button in the Web UI, sometimes Server 2016 shuts down without issue, but other times Proxmox gets Error "TASK ERROR: VM quit/powerdown failed - got timeout".

  7. ISCSI LIO targetcli no config after reboot

    Hi @ all, I am expiriencing the problem that targetcli is not reloading the saved configuration in "/etc/rtslib-fb-target/saveconfig.json" after a reboot. So always after a reboot you need to do the command: targetctl restore /etc/rtslib-fb-target/saveconfig.json In the man page of targetcli...

  11. [SOLVED] Proxmox "apt upgrade" restart needed?

    Hi @ all, I am asking myself when a server really needs a restart after a "apt update & apt upgrade & apt dist-upgrade"? For example having a server with version pve-manager/5.3-5/97ae681d (running kernel: 4.15.18-9-pve) Ok sure if I upgrade the kernel to the newest "4.15.18-10-pve" I would...
  12. KVM Page Cache vs Proxmox ARC

    Hi @ all, I am experimenting with KVM Linux Guests (Debian) and asking myself if it really makes sense to have Linux guest OS use Page Cache at all? Because, as I understand, ARC should do the exactly same stuff directly on the node, right? But how to disable it at all in the guest, as sysctl...
  13. qm migrate --online --with-local-disks -> is copying block level

    Hello @ all, I am wondering if it is really nececerry to use block-level copying on "qm migrate --online --with-local-disks"?

  14. qm migrate -> deletes pve-zsync zfs snapshots

    Hello @ all, we are experimenting with the zfs live migration and have recognized that the migration to another node, will delete all the existing pve-zsync zfs snapshots. So that on the next backup pve-zsync will fail. Any idea if there is a option to kepp the snapshots on live migration...

  19. Separate "private networks" for VMs

    Hello @ all, I want to configure private networks for VMs, so that certain VMs can communicate directly with each other on a private IP. My first though was to create multiple virtual bridges "vmbr1" to "vmbr10" to have for example 9 different virtual private networks. Would this be the...
