good day to proxmox team and forum members,

i will upgrade my current (underpowered) ups to a more beefy one (most probably from Eaton or APC) and i dont know how to best connect my 3-node cluster to it.

The ups wil most probably has only one USB connection and i was thinking of connecting each node to the ups through a usb hub, the hib then to be connected to the usb itself.
Then, install nut on each node finally spin up a peaNUT server to monitor each nut client. This way, once a power...

Hello All,

I'm trying to get LACP working on a bridge interface.

Some background:

The bridge interface comprises 1 bond: 2 10g SFP connections to a Cisco 2960-X switch. Those two ports are configured as trunks in a channel-group, LACP.
Port config from switch here:

description ProxMox Trunk r330
switchport trunk allowed vlan 1,10,20,30,66,99
switchport mode trunk
channel-group 1 mode active

I have the SFP+ connected to a card on my server, enp1s0f0, and enp1s0f1

HOWTO - Proxmox VE 8-1.2 Wifi w/ SNAT

This is a HOWTO for configuring Wifi for Proxmox VE 8-1.2 w/ SNAT. I've read a bunch of various writeups but none of them are consistent so hopefully this will be a one-stop shop for people to get Wifi w/ SNAT configured. Hopefully this can be added to the Wiki.

Note: This configuration DOES NOT use DHCP for anything. It uses all static addressing.



Prerequisites:

1) Wired ethernet connection - this is required to install wpasupplicant

2) Configure your wifi router to route...

Quite a few changes with vGPU software on Kernel 6.8. The feature is called "Vendor-Specific VFIO Framework".

Note you will need 550.90.05 for this to work which you can download from nVIDIA. Things like mixed size vGPU (you can now have different memory allocations on the same GPU) and live migration on KVM are now a feature (haven't tested that feature yet, more to come).
Note: current versions of the 535 and perhaps other branches may now work as well (which you may need if you are...

Question about making a public mirror for pve-no-subscription

$

Hello,

I am currently an administrator who manages a mirror server at KAIST.

First, Thanks to Proxmox GmbH for developing the open-source virtualization solution.

In Korea, the Proxmox repository server is slow, so I am considering mirroring Proxmox.

Technically, I know that mirroring using pom and serving it works, but I wonder if this is possible in terms of policy.

Thank you.

PVE Recovery

I moved recently and now have a new ISP. I am unable to connect to my pve and need help getting back to the environment. I have tried messing around with the CLI and switching IPs and whatnot. Ultimately I need the help of someone smarter than me :)

I've changed my gateway IP and host IP. I used these commands to do so, 'nano /etc/network/interfaces' & 'nano /etc/hosts'

Please help, I'm stressing over here.

Migrating PBS: Syncing to Another Server

Hello everyone,

I have a few questions for which I haven’t found precise answers, and I’d like to clear up any doubts.

Context:
We have two separate backup servers, each with its own datastore. Server A is a fallback server used in case of an issue with Server B. We store the last three months of backups on Server A. However, Server B does not have enough storage to retrieve everything stored on A.

I would like to free up some space on B, and I’m wondering if, after cleanup, a...

I have a cluster with three Proxmox servers connected via Ceph. Since the beginning, the effective storage was 10TB, but over time, it has decreased to 8.59TB, and I don’t know why. The filesystem is RBD. Why is my Ceph RBD storage shrinking? How can I reclaim lost space?

use smtp to send ALL notifications

Hello,

I added an SMTP "Notification Target" from the notification screen it works fine (tested and mail received).
I disabled the "mail-to-root" target as I wanted to use the SMTP target for all notifications.
I also updated the notification matcher to use the SMTP target instead of the "mail-to-root".

But I'm a bit surprised that I still see logs that it's not possible to send mail using port 25 (it's blocked by my ISP):
Code:

After launching a replication, the task failed and I've received the following error :
Code:
end replication job with error: No common base snapshot on volume(s) local-zfs:vm-102-disk-0
Note that there are no snapshots associated with this VM.
Also, I've had this error with VM's and CT's too, neither having snapshots.

Then when trying to remove the destination disk, I get "zfs error: cannot destroy 'rpool/vm-102-disk-0': dataset is busy".
Also note that the replication seems to be borked...

Running 2 node HA, kernel-helper package update, after reboot, node 2 not connecting to HA

Hey everybody. Kinda new to Proxmox as I have been running it for a couple months in a 2 node HA cluster. I noticed there was a package update this morning for I think it was a kernel-helper package and after doing the update node 2 said I needed to reboot to take effect. I rebooted node 2 and now it's disconnected from my HA cluster. The node is back up, I can ping it, I can ssh into it, and I can actually access it through the shell menu in my node 1 proxmox GUI but the node shows with...

Correct way to edit cron jobs?

Hi,

what is the correct way to edit cron jobs on the Proxmox host?
In the file "/etc/crontab" I can see some default content:
Code:
root@pve:~# cat /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
