Installation Stuck

Finally installing Proxmox on bare metal server for the first time. Yesterday I got through to the installation screens without an NVidia video card i.e. through the motherboards on board VGA apator and an old monitor. However, this didn't work because there was a warning in the middle of the screen from the monitor which blocked all installation options. So today I installed a video card and connected a different monitor which has the appropriate DVI atapter.
Now the installation hangs...

PVE8.2 how to properly reinstall Ceph?

Running through a few DR scenarios and our scripts we used to reinstall Ceph (both at the cluster level and per node) are not working under 8. While we can pull Ceph off the node/cluster, when we go to add the 2nd node back in(on either an existing or new install) Ceph blows up at the cluster level and all Ceph members go back to an unconfigured state.

Below is the purge scripting we use, what are we missing?
-Mind you, we want to be able to do both a full cluster rebuild on Ceph if...

After I executed the command apt upgrade && reboot, I can't start pve, I get this error:

If I select kernel 6.8.12-4-pve, it can boot.

As a temporary measure, I switched to the old kernel "pve-efiboot-tool kernel pin 6.8.12-4-pve".

What should I do ? thx.

On Proxmox VE 5.1, inside an LXC container, I cannot ping with unprivileged user. It gives me the following error:

Code:

ping: socket: Operation not permitted

On the hostnode itself I can ping with both unprivileged user and root, but inside an LXC container only as root.

The following fixes it and gives all unprivileged users the required privileges to a open the socket:

I've decided that I'm going to remove my 2nd Proxmox node and go pfSense on baremetal. I had some issues last week and as part of that I started to play with the cluster, ultimately I ended up running the following that I found in another reddit post:

systemctl stop pve-cluster corosync

pmxcfs -l

rm -r /etc/corosync/*

rm /etc/pve/corosync.conf

killall pmxcfs

systemctl start pve-cluster

What I'd like to know, is there a way to do a health check on my primary host before I completely...

Moin, liebe Gemeinde!
Ich habe auf einem PVE-Host ein paar Container, als auch VMs laufen. Alles schick so weit.
Heute habe ich festgestellt, dass ALLE VMs keine Verbindung zu einem Zeitserver herstellen können (z.B. 2.debian.pool.ntp.org).
Ein PING ergibt 100% packet loss. Die CTs funktionieren einwandfrei und auch der Host synced brav. Firewallregeln fallen aus, da die Firewall aus dem RZ bemüht wird, also es für alle Maschinen gleich ist. Der timesync Service läuft. Der Befehl timedatectl...

Proxmox Helper Scripts - Do you all just spin up many LXCs or try to combine them??

I know that using LXC Containers is more resource friendly than using a full VM because you share the kernel and some other things among all the containers. Cool.

Now I have run in to many different apps that are easily deployable using the Helper Scripts and it is super cool that one-click and they are up and running.

I'm sure many of you have experienced the same.

But... is there any worry about wasting resources by having so many LXC Containers running for some pretty simple apps...

Hello everyone,


I have a node that is almost out of storage, so I added an additional node to the cluster to offload some VMs. However, I am unable to migrate them because they are stored in LVM-Thin, which does not support direct migration.


I attempted to set up a shared storage on the new node using ZFS, but it was unsuccessful. I also tried using Proxmox Datacenter Manager, but I couldn't make it work.


At this point, I urgently need a solution to move my VMs...

Issue Summary​

I recently encountered an issue where the Proxmox GUI would hang indefinitely when navigating to My Node > Disks, eventually displaying a "Communication Failure" error. However, the disk in question was fully recognized in the CLI (lsblk, fdisk), and I was even able to manually mount it. After debugging, I found that the issue was related to SMART data retrieval in Proxmox’s API. Disabling SMART queries resolved the problem...
