    Hello everyone, I installed Proxmox (7.2-4) using ZFS (RAID1) and one of the two drives have failed. I thought Proxmox would use both entire disks for the ZFS rpool during the installation but it appears Proxmox created three partitions and included only one partition in the ZFS rpool. With...

    Hello everyone! I've been using Proxmox on NUC's for a while now and recently purchased a new ASRock NUC Box 1165G7 then installed Proxmox 7.1 as a ZFS mirror on two internal disks (Sata SSD and NVMe M.2). I started experiencing odd things where pings and the Proxmox UI would stop responding...

    Hello everyone, I have a fresh install of Proxmox 7.1-7 with the WebUI being on a 192.168.1.0/24 network and I'm trying to access it from a 192.168.35.0/24 network.

  6. What's Causing My External USB HDD To Mount After A Reboot?

    Hello Everyone, Using Proxmox 6.2-14, is there anything built in to Proxmox outside of: /etc/fstab that would cause my external USB HDD to mount after a reboot? I previously added this USB HDD under: Datacenter --> Storage --> Add --> Directory but it has since been removed and is not listed...
  7. [SOLVED] Mailq Shows Undelivered Emails But I Do Not Have Postfix Setup

    Hello everyone, I have a Windows 10 VM (with the latest updates) running on Proxmox [pve-manager/6.1-5/9bf06119 (running kernel: 5.3.13-1-pve)]. I've gone into the OVMF EFI settings and adjusted the resolution to 1920x1080 but booting back into Windows 10 I'm still stuck at the 800x600...

  13. Where Are The Default Firewall Rules At?

    Hello Everyone, According to the Wiki: "If you enable the firewall, traffic to all hosts is blocked by default. Only exceptions is WebGUI(8006) and ssh(22) from your local network." My question is, where are the configuration files for these two rules (WebGUI and SSH)? I checked in...
  14. Is It Best Practice To Use Proxmox Firewall or Firewall In VM?

    Hello everyone, Just curious what others are doing, but is it best to use Proxmox's firewall that is available in the webgui for each VM or use the VM's firewall available within the OS (e.g. ufw, firewalld, etc...)? I'm on Proxmox 5.2-2 and most of my VM's are a Linux distro (Ubuntu, CentOS...

  16. [SOLVED] ZFS Missing or Invalid Label Issue

    Hello everyone, I came across this error on one of my Proxmox installations and although replacing the bad HDD would more than likely fix the problem I was concerned that the output of zpool status -v is saying the failed disk was the same device name as the online disk. Shouldn't the device...
  17. [SOLVED] Install Proxmox 5.1 on USB Flash Drive?

    Hello Everyone, According to this older thread installing Proxmox on a USB flash drive was discouraged. Is that still the case with Proxmox 5.1? FreeNAS, for example, encourages installing onto a USB flash drive for their ZFS setup. That's why I was wondering if this has changed for the...

    Hello Everyone, In the ZFS: Tips and Tricks Wiki about 3/4 the way down discussing copying the partition table, it appears the syntax for the sgdisk command is wrong: root@pve:~# sgdisk --replicate=/dev/sdb /dev/sda /dev/sdb is the failed disk and in this example we are suppose to be copying...

    Hello, I am testing PCIe Passthrough on a friend's Proxmox machine (kernel: 4.4.44-1-pve) before I purchase any hardware for myself so I wanted to ask before moving forward with patching the kernel if that becomes necessary.
