I have (had?) a ZFS pool setup through proxmox that stopped working. All the disks in shows up in Node > Disks, with "SMART: PASSED" but "Mounted: No"

After that i also saw that my interfaces are down. I also tried to bring them back up.

Here are the Photos for some information:

Windows RDP Performance

Hallo,

nehmen wir kurz folgendes Szenario an.
Man greift von einem Win11 Laptop per RDP auf eine Win11 VM zu die auf einem Proxmox Server läuft.
Ist die Darstellung auf dem Laptop dann flüssiger, wenn man der VM eine GPU per Passthrough zur Verfügung stellt oder ist das von der Performance her unerheblich?

Hello there,

I have seen a couple of comments on Reddit & Github that raidz expansion is currently being developed/has already beta state.
Will that feature also work for PVE or do I still need all disks available at zpool create?

SOLVED: NAS storage, limited space available

Hi,

I've searched the complete afternoon but can't find the right answer :-(
In PVE I've added my Synology NAS (via SMB and NFS) and it's showing the right disk capacity and used space. Capacity 9,83Tb, free space approx 2,46Tb.
Synology Proxmox.png
I've used the NAS to store the PVE backups (not PBS) and that worked okay.

Today I've installed the latest version of PBS (in a container and vm, just to find the differences).
If I add the Synology using 'add Datastore'. The datastore is added but the...

I just finished migrating my Windows 11 gaming VM from Unraid to Proxmox. Along the way I encountered some obstacles. To hopefully save other people some time I'm writing a detailed guide here on how I set up my system.

Disclaimer: I am by no means an expert on this stuff. It is entirely possible that I made some mistakes in this setup. If you notice something that is clearly wrong or something that could be improved please add your suggestions in the comments.

Hello Community,

I installed proxmox on a Strato VPS (KVM). Knowing, that virtual machines will probably not work but only containers - which is acceptable for me at the current state of the project.

1. I followed the instructions from https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm
1a. The reboot after installing the new kernel executed successfully
2. At the end of the guide, I have a working proxmox, including WebGUI, no obvious errors
2a. The error is...

Can PBS act as SAN as well?

I have been tasked with building a production Proxmox system where the intention was to have two PVE servers in a cluster, plus one PBS system to provide storage and backup services (and to be a QDevice). When it was designed, the PBS is the sole storage system and therefore has all the large SSDs (five 7.68TB SSDs), and the two VM servers contain just a basic 400GB SSD each to house the PVE host OS.

The assumption was that PBS would be a large storage pool that would be used for both the...

Allow unifi container to use multiple VLANs

My goal:
  • Have my unifi container's management IP and Office wifi network be on an untagged vlan (currently works)
  • Add other wifi networks with different vlans (ie guest vlan: 55, accounting vlan: 100)
Where I'm at:
Office wifi network works great. I can connect and get an IP as expected. However, I created a guest wifi network with vlan 55. When a client connects, they do not get an ip address.

SDN with EVPN controller: Routing loop when using multiple exit nodes

Hi all,

currently I am trying to set up a cluster with SDN with an EVPN controller using multiple exit nodes, but I can't get around an issue with a routing loop.
The packets I send are stuck in a loop between both exit nodes and never forwarded outside of the cluster.
Each exit node has a default route to the other exit node, forwarding the packet to the other node instead of sending it outside the cluster.

I confirmed this using tcpdump on both nodes, showing the same packet (sequence...

Hi,

I am not happy with current ceph balancer as there is too big difference in number of PG per OSDs.
I would like to try upmap-read but all clients must be reef, however they are luminous.

Why Proxmox use luminous clients for reef ceph? Can I change it to reef and activate upmap-read balancer?

Code:
