    3 node proxmox link failure, reboots node even when second link is up

    You can see the status of both "rings" this way: ~# corosync-cfgtool -s Local node ID 6, transport knet LINK ID 0 udp addr = 10.3.16.7 status: nodeid: 1: disconnected nodeid: 2: connected nodeid...

    ArchLinux not found in LXC template

    That's not an arch-specific "problem". While the download page lists debian 10/11/12/13 only 12+13 are integrated in the PVE 9.x offerings. So my personal understanding is that only compatible and tested distribution templates are actually offered in each release. Disclaimer: I run VMs, not...

    Migrating PVE install from flash to NVMe

    Did you test that? I know that you know that pve is a fuse-mounted database; a snapshot of the "/"-filesystem is... empty: ~# ls -Al /.zfs/snapshot/manual/etc/ | grep pve; echo "inside pve:"; ls -Al /.zfs/snapshot/manual/etc/pve/ drwxr-xr-x 2 root root 2 Aug 26 2023 pve inside pve...

    Per-node resource allocation view in PDM / Proxmox cluster

    I cannot answer your question, sorry. I just want to mention this project: https://github.com/credativ/ProxLB From my limited(!) point of view PDM is meant to be helpful when managing multiple and independent clusters (or multiple single hosts).

    [PVE 9/ZFS-Based VM/LXC Storage] Why Shouldn't I Disable Swap Inside Linux VMs?

    Correct. That's the reason I didn't test it myself, yet. Please do not hesitate to tell us you findings :-) Fortunately my professional cluster has more physical Ram than it needs. And for my homelab I bought some MiniPC with 128 GiB Ram just before the current craziness emerged. Now for...

    new drive setup, considering RAIDZ1

    This gives the IOPS of a single spindle. Recommended is to use (two) mirrors --> double IOPS for writing data and four times the IOPS for reading data. And... for rotating rust I highly recommend to add two fast - but small - SSD/NVMe as a so called "Special Device". It really speeds things up...

    IBM Plugin

    Is there some documentation for that plugin? It should show details about the supported protocols and features, right?

    [PVE 9/ZFS-Based VM/LXC Storage] Why Shouldn't I Disable Swap Inside Linux VMs?

    Did we mention this (much newer) article in the other threads? https://chrisdown.name/2026/03/24/zswap-vs-zram-when-to-use-what.html I must admit that I haven't had zswap on my agenda at all. I read the article twice - and did not understand it completely... :-(

    What are these default root crontabs and what do they do?

    Note that there may be additional systemd-timers, which are not visible in the classic crontab context. Run systemctl list-timers -a instead. You also did not mention user-specific crontabs, editable by everybody by crontab -e - including one for the "root"-user.

    [SOLVED] Zfs boot disk replacing

    Well..., I hesitate to answer - because none of my machines has "booted with legacy bios", all of them report "booted with uefi".

    [SOLVED] Zfs boot disk replacing

    There are multiple symbolic links pointing to the same device. My example shows that in detail: https://forum.proxmox.com/threads/fabu-how-to-select-the-correct-disk-or-what%E2%80%99s-in-a-device-name.182741/

    [TUTORIAL] FabU: how to select the correct disk, or: what’s in a (device)-name?

    The different names for disks may lead to confusion. I show some different names to specify the "right" device. Why is this important? Well..., the obvious thing is that “zpool create” will destroy the old content. You will lose any data stored on it. And the “classic” names like “sda” may...

    Geo IP block help

    From my point of view it is not best practice to connect a PVE cluster directly to the outer internet. There should always exist a router with filtering capabilities. In that picture the router would do Geo blocking, beside other things. My recommendation is to re-evaluate the possibility of an...

    PDM: migrate VMs across firewall

    There is no additional PVE involved ;-) The "external relay" is just a common reachable rendezvous point to establish the tunnel. All payload traffic would then go through this device, which vastly influences the reachable bandwidth. Automatically for the chosen subnet - which needs to be...

    PVE9 VM suddenly stops when finishing backup to PBS

    I would further slow down. My goal would be to adjust to the speed the PBS is actually capable to absorb - to keep the fleecing file small. If that runs stable I would (relatively) slowly increase the bwlimit. Just my thought... and a very slow and time consuming process.

    PDM: migrate VMs across firewall

    My personal choice would be to establish a Wireguard tunnel. My preferred method is to handcraft something like https://www.wireguard.com/quickstart/. But this requires one endpoint to be able to reach the other one; in a single direction is sufficient. If that is not possible I build an...

    Proxmox installing to incorrect nvme disk

    My thoughts: Erase both disks. Completely! (If you just delete partitions some signatures may still be present.) Use any rescue image to boot and run something like "dd if=/dev/zero of=/dev/nvem0 bs=1M status=progress" for both of them. Remove nvme1 during installation. Then there is only one...

    Was soll der Architektur-Eintrag in den LXC-Optionen?

    Und das war ein Fehler. Es suggeriert aktiv, dass es keine anderen Hersteller gab/gibt. Doch. Es weist nämlich darauf hin, dass Zellstofftücher nicht unbedingt "Tempo"-Taschentücher sind. ;-)
