Rules applied at the DC level apply to all nodes. Rules applied at the node level apply to the individual node. Rules for VMs/CTs need to be applied to the VM/CT. If you have sets of rules that apply to several guests, make use of Security Groups. There you can define the rules and then insert...

I was in a similar situation a few years ago. That where that guide came into existence. My advice is to test it in a VM first where you recreate the situation. Then you know the procedure and might can adapt it to your needs before you do it on the actual system.

Aaah, jup duplicate IP Probleme sind meh... :)

Ich sehe da jetzt nicht groß ein Problem mit dem Ansatz. Alternativ, wenn der Platz da ist, jedem Host einen ZFS storage geben? Dann kann die VM bleiben und man muss nur die Disks mit Move Disk verschieben. Noch alternativer, je nach use-case wofür Snapshots benötigt werden: Falls ein Proxmox...

Wurde der Traffic zum NFS dann via Router ins richtige Netz geschickt anstatt dass der Host direkt mit dem NFS share redet? Damit ich das auch verstehe :)

If you checkout the web UI: {node}->Updates->Repositories you can use the UI to disable the enterprise repos and configure the no-subscription ones without touching the CLI.

Things to check: * RAM memory test (included as advanced option in the Proxmox VE ISO) * anything overclocked? like XMP profiles for memory? * Power supply still working well enough? Random reboots can be tricky to troubleshoot unfortunately

There is works going on to make it easier to use external disks on PBS and also to import disk images and/or OVA packages AFAIK. When they will be done is a different question though :)

You could download these img files and when you need to restore them, first create a new VM (maybe without a disk) and then run qm disk import {vmid} /path/to/image {target storage}. But as others mentioned, other approaches would most likely be better.

Ein 5315Y hat 8 Kerne / 16 Threads. Das ist jetzt nicht so viel, je nachdem was alles auf dem Host läuft. Nein. Das hat auf die Performance einer VM keinen Einfluss. Ich meinte den IO Wait, welcher der zweite Graph im CPU Load Graph ist. Dieser ist ein Indikator, wie lange Prozesse darauf...

2 sockets mit 3 cores ist ein wenig seltsam. Ist der Server ein Multisocket System? Falls nicht, die Sockets lieber mal auf 1 und die Cores auf 6 geben. Was für eine HW hat der Server selbst? CPU cores/threads? Wie schnell ist die Anbindung an den NFS share? Sieht du im CPU/IOwait Graph auf...

Do you see any issues in the syslog/journal of the backup server around the same time that indicate some IO problem? I remember a case in our paid support where a customer ran into similar issues, that some commands would always be failing with an I/O error. In the end, the cause was that the...

From the first post: Needs new pve-manager 8.2.8 which is in pvetest only for now.

Thanks, I fixed the docs!

https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-server-on-proxmox-ve That is what I am using myself hat home where I only have a single server.

Unpriviledged LXC? Then you will have to allow access to the device(s) to the container. Alternatively, a priviledged container might work. Or if you already fix the PBS hard on that node, installing it side by side bare metal should also not come with any downsides that you don't already have.

If you use a somewhat recent virtio ISO, there should be an installer that will install all the virtiIO drivers and services (guest agent, ballooning). Otherwise you will have to manually install the drivers as they are needed. And yes, if you want to use the virtio network device, the drivers...

And with a recent Proxmox VE version, the GUI should now offer a second CD drive in the VM create wizard directly if you choose Windows as guest OS

Change the network config to use the correct GW? Otherwise, please provide more infos! What is the current network config of the host? (cat /etc/network/interfaces) and what is actually applied? (ip a, ip r)

A bit more infos would be useful. Config of the VM (qm config {vmid}). Is Ceph healthy or does it show any warnings? What is the actual error in the task log of the VM start?
