Hi, Thanks for the reply. Yes I agree, our other clusters we own are all on private IPs only accessible via VPNs, but in this case we have a 3 node cluster with a server vendor in a Datacentre in London. The Datacentre, do not offer... -
UdoB replied to the thread [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...

UdoB reacted to Johannes S's post in the thread Proxmox Backup Server configuration , change listen address and port with
Like.
One possible alternative to VPN is to use s reverse proxy as described by @meyergru https://forum.proxmox.com/threads/using-a-reverse-proxy-to-limit-pbs-exposition-to-api-endpoints-only.182188/ Personally I would still use a vpn like wireguard... -
thanks to your help, here is what I did and seems to work (I did reboot on each sole drive to validate the boot mirror => it's ok) I give all if it can help other people: me@myhost:~# sgdisk /dev/sdf -R /dev/sdb The operation has completed...

UdoB replied to the thread 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...

UdoB reacted to Mike_Scholes's post in the thread Migrating Servers/Fresh Installs - Sanity Check with Like.
Suppose it would work but if you lose the primary server you then lose your backup server if it's a vm. Just more hassle recovering as you would have to install a backup server somewhere in order for you to access your backups. Personally my home...

Looks like the boot partitions are under proxmox-boot-tool's control. You'll need to remove the old ESP and add the new one on the new drive, using proxmox-boot-tool format and proxmox-boot-tool init as the manual prescribes...

UdoB replied to the thread [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".

UdoB reacted to Johannes S's post in the thread [TUTORIAL] PoC 2 Node HA Cluster with Shared iSCSI GFS2 with Like.
But PVE has snapshots on lvm/thick although that feature is still in technology preview

UdoB reacted to gfngfn256's post in the thread error smart on disk SDA but from gui not confirm this . with Like.
Since it appears that the Current_Pending_Sector has not risen (19) since May 2025, & assuming this is a server that the drive is in constant use, it is possible that the drive is still "usable" or may even be perfectly alright. However this is...

UdoB replied to the thread [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/

UdoB posted the thread [TUTORIAL] FabU: how to select the correct disk, or: what’s in a (device)-name? in Proxmox VE: Installation and configuration.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...

UdoB replied to the thread 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...

PVE blocks changes to cluster file system: 1. Stop the cluster services on the node you're changing (Server5) systemctl stop pve-cluster systemctl stop corosync 2. Mount pmxcfs in local mode (bypasses cluster lock) pmxcfs -l 3. Edit...

UdoB reacted to Johannes S's post in the thread Internetzugriff auf Proxmox VMs / Docker Container hinter OPNsense mit Reverse Proxy with Like.
Weil sich bislang kein/e Freiwillige/r zum Maintainen gefunden hat, wäre meine Vermutung.

for all intents and purposes this could be malware, so no thanks. not going to trust an unknown exe from a source without known good reputation without available sourcecode.

UdoB reacted to TErxleben's post in the thread Internetzugriff auf Proxmox VMs / Docker Container hinter OPNsense mit Reverse Proxy with Like.
Geschichten, die das Leben mit LXCs schreibt und es hierhin passt. Ich setze seit gefühlten Äonen Apache Guacamole als Fernsteuerungsproxy ein. irgendwann kam ich auf die naheliegende/dusselige Idee, selbiges zu virtualisieren Da ich damals noch...

I use headscale, too. But establishing a common network between my otherwise segregated PVEs means to circumvent my inner firewall. If I were willing to do this, it would easier to remove the firewall instead of making an effort to circumvent...
-
There are also alternatives to tailscale who works similiar ( they all base on wireguard) like netbird or headscale and there are even more. Personally I use headscale which is an open source Implementation of tailscales protocol. For your...
