Hi.
So I added new SSD. 2TB NVMe.
I did move some VMs to this SSD, I need free up space. at this moment proxmomx shows full VMs disk full size in admin panel
So I did enable dsicard on, than did login in Ubuntu 20.04 guest and did run trim commands.
But proxmox panel is showing there is no space on disk enough.
When I run zpool list, I see different values, which could more true with space.
Like here is picture about where free space for disk 1.37 tb.

Tape Backup: PBS markiert alle Medien innerhalb des Pools als "full" sobald ein Backupjob gestartet wird.

Hallo,

wir haben PBS seit längerem im Einsatz. Wir führen damit auch Sicherungen auf Band durch (Quantum Superloader3 mit LTO8 Medien).
Wir mussten nun unsere Medienpools um jeweils 1 Medium erweitern, da der Speicherplatz eines Bandes nicht mehr ausreichte.

Wir haben 2 Backup Jobs die auf den gleichen Medienpool sichern. Der 1. startet Montag morgen, und der 2. Backupjob startet Freitag Abend. Uns ist aufgefallen, daß PBS beide Medien als "Full" markiert sobald der 1. Backupjob startet...

Proxmox VE installed version in the web GUI is different to the ISO filename

Hello everyone. This is my first Proxmox forum post - please be kind :-]

I just installed Proxmox VE using the ISO called:

proxmox-ve_8.2-1.iso

I installed to a Dell R660 PowerEdge server.

For security reasons the server does NOT have any connection to the internet.

The install went through without any errors and I can login to the web GUI running on port 8006 and can upload ISO files and create virtual machines.

So what is my question?

Well, on the web GUI the version of Proxmox is...

Demo-Setup Proxmox + vGPU / Recommendations?

Hi there,

we're using VMware ESXi/VCSA in our productive environment and want to try if Proxmox could fulfill our needs.

We're using a CAD software (2D) in some VMs that are dedicated to single users. This software got an update and is now able to do CAD in 3D, which will need 3D hardware acceleration.

I would like to do a POC with Proxmox, following this article: https://pve.proxmox.com/wiki/NVIDIA_vGPU_on_Proxmox_VE. In addition, we're using VMware Horizon for lag-free remote...

Hello

Even tho Ubuntu 24.04 is in the proxmox repo we still get

unsupported Ubuntu version '24.04'

from what i can gather its not supported yet. (even tho its in the repo.)

what we can do is add 24.04 as a known verson in this file /usr/share/perl5/PVE/LXC/Setup/Ubuntu.pm

i will try and wait for the fix to be official. :)

Please fix this soon Proxmox devs, you are awsome :D

Hello there,

I'm trying to migrate from ESXI to Proxmox. I only have server, so I've simply added a 990 pro to the server. I installed Proxmox on it, and was hoping I could mount the 980 pro (on which ESXI is installed, and on which all of the VMs are) - but it appears to be impossible to mount and run the ESXI Vms from the existing 980 pro.

Is there any way to mount the 980 pro with ESXI on it, find the VMDK's of the VMs and simply run them, or move them to the newly added 990 pro...

What are people doing for cross-site replication?

I know of only a few options;

- Not cross site, but Proxmox natively ZFS replication
- Storage level replication, eg ZFS, or natively through the appliance like Pure Storage or perhaps something like Starwind VSAN
- Ceph to Ceph - https://github.com/lephisto/crossover

Not considering Proxmox Backup Server, Veeam Backup & Recovery or Vinchin Backup as they are exactly that, Backup, not DR.

I have tried rsync before, however it struggles to only transfer incrementally, it often will...

It seems the ACME DNS plugin he for hurricane electric is broken. It only has a field for "api" which HE doesn't actually have. If you look on the acme.sh GitHub page explaining how it auth's with he.. it mentions exporting HE_Username and HE_Password, however I've tried putting these values in the "api" field within Proxmox every which way and none of the ways result in the dns plugin authing with hurricane electric. I've done a few searches on this subject, but came up empty handed.. I'm...

Official way to backup proxmox VE itself?

Is there any official guide on how to backup proxmox VE itself?

My main concern is the amount of work that I have put in to make the current setup work, e.g. GPU passthrough etc.
If that breaks due to updates etc, I would like to have a way to quickly revert back to the last known working state.

Is Proxmox backup server able to do it? and is it the only way?
Or is there some way that is built-in to Proxmox VE itself?

We are working on a remote cluster of PVE machines and a PBS machine to act as an off-site backup of our local PBS, as well as provide some disaster recovery options. Ideally, we would build out the disaster recovery site to be identical to the local cluster, however costs are prohibitive at this time.

PBS has the ability to do a 'live restore' where a VM boots up and uses the PBS storage until the VM has been restored to local(or ceph) storage. Is there any ability to run a VM fromthe PBS...

Hello, I want to build a Proxmox host that I can also use as a standard workstation and I would like to know if anyone can advise what pitfalls to avoid.

I intend to have Proxmox as the only OS on the machine and use a desktop KVM connected to the onboard USB & video output so that it uses the CPU's integrated graphics chip. The KVM will also have a connection to the PCIe GPU and another USB port for mouse/keyboard/gamepad. My theory is that this will allow an easy switch between the host...
