Dear community,

I'm new to proxmox and now stucked with uid / Gid mapping for my nfs share mapped to my container.
Here is my lxc-conf:

hostname: plex

mp0: mp=/mnt/media,path=/mnt/media
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=bc:24:11:b7:12:65,ip=dhcp,type=veth
ostype: ubuntu
rootfs: local-lvm:vm-105-disk-0,size=20G

Good afternoon All,

I have been frantically attempting to resolve an issue that, i have to admit, has been keeping me awake at night. Like lots of people, i have been migrating away from ESXI and over to PM VE. So far so good with my homelab server.

I have a fresh install of the latest 8.2.2 on a ZFS SSD, set iOMMU to on, followed every tutorial i can find but when i attempt to pass my HBA card through to a VM, i get the error below. It did work fine in ESXI so i know the bios is set...

Hi Everyone!

I decided to write a tutorial for PCI/GPU passthrough for the HPE ML/DL servers, because many information you can found is old/misleading and not working.
Here you you can found the a working method.


1., Requirements:
Code: 
-HPE ML/DL series server
-PCI-E card / GPU card
-ILO access


2., BIOS Settings:
Code: 
F9 BIOS (RBSU), and Press CTR+A (Hidden menu will appear at the bottom "Service Options"):

- "System Options" > "Intel(R) VT-d" > "Enabled"
- "Advanced Options"...

LXC Usage Graphs in GUI Blank with Wrong Date/Time

I swapped to a new motherboard and initially upon boot the usage graphs of the host were empty, showing 1969-12-31 (screenshot below). I followed some instructions in this post, which fixed the issue for the pve host.

However, I'm running into the same issue for all containers and VMs. I tried deleting the file for an individual lxc, e.g., rm -rf /var/lib/rrdcached/db/pve2-vm/102, and then systemctl restart rrdcached.service, to no avail. The date/time in the LXCs...

Hi everyone!

1000066435.png
Can you help me with my internal network please?

I have a cluster with 2 nodes, my internal network is managed by PFSense on node 2 (x.4). I passed NIC 1 directly to the VM and NIC 2 connected with bridge and use vmbr0 as lan in PFSense. In this mode, all traffic goes through my PFsense.

I created a Vlan 100 derived from vmbr0 to segregate my devices.

For example, on node 1 (x.3), I created a lxc and set the bridge network as vmbr0.100, but without success, I...

VMs in multiple backup jobs

HI, I'm trying to work out the best way to achieve something like the following:

A backup job that performs a nightly backup of every VM on the cluster with no exclusions. This is a failsafe job to ensure that we don't forget to backup a new VM, and for many VMs a simple nightly backup is adequate.

A second job that runs hourly and keeps good historical retention, for those VMs that require it (e.g. file and database servers).

I am finding that VMs that appear in both jobs keep getting...

Validation using API Token authentication (with regex)

Hey,

I am using the Proxmox VE API in my app, and I want to create a whitelist for fields related to authentication: Hostname, Username, Realm, Token-ID, and Secret.
I use regex to ensure only valid characters are inserted as part of the authentication. I have two questions:
  1. As far as I know, the realm can only be one of the following: “pam”, “pve”, “ldap”, “ad”, and “openid”. Am I right?
  2. Is the secret always a UUID?
Thanks

Moin,
wie kann man aus 2 x 2 M.2NVME SSD und 2 x SATA SSD die beste Leistung raus bekommen?

Wenn ich diese 4 Laufwerke in ein ZFS konfiguriere, wie wirkt sich das auf die Leistung aus oder sollte man besser 2 ZFS Volumes anlegen?

Also eins mit 2 x 2 M.2NVME SSD und eins mit 2 x SATA SSD.

proper versions for upgrading Reef to Squid

Hi,
I'm going to be upgrading my ProxMox hosts from 8.2.4 up to 8.3.1 and my Ceph from Reef 18.2.2 to Squid. I'm following the directions here (https://pve.proxmox.com/wiki/Ceph_Reef_to_Squid) for ceph and I'm wondering if I can go from Reef 18.2.2 up to Squid directory? In the Introduction section of that document it says Reef(18.2+) to Squid but then in the "Assumption" section it says 18.2.4-pve3 or higher. Can I upgrade from 18.2.2 or do I need to be at 18.2.4?

Thanks

I previously wrote up a HOWTO for configuring Proxmox 8-x.x Wifi with SNAT and am now providing a HOWTO for Wifi with a routed configuration. The reason why I ditched the SNAT configuration is because I simply wanted full routing capabilities between VMs/containers hosted with Proxmox over Wifi and the rest of my network devices. Specifically, I wanted to use barrier to share my mouse and keyboard with my Windows VM that runs iGPU passthrough for my Ryzen 7840HS w/ Radeon 780M...

Hello everyone,

I have a server where PROXMOX 8.3.3 is installed. On this server, I have a USB 3.0 LVM key 512Gb. Is it possible to install Windows 11 on this USB key using it as a SCSI disk in the dedicated VM?

If this is possible, how would you do this?

Thanks in advance

I have problem with backup and disk or Kernel

Hello everyone,

I’m experiencing issues when running backups on Proxmox. Every time I attempt a backup, the machine returns the errors shown in the screenshot.

1739261717344.jpeg

I suspect the problem might be related to the disk, but I also have doubts that it could be caused by the Kernel. Has anyone encountered a similar issue or has any suggestions on how to fix it?

Proxmox Version: 8.3.3
Kernel Version: 6.11.11-1-pve

Thanks in advance for your help!

Verify State error "old" in Yellow - what to do?

Hello!
I have PBS installed in a VM, it's been running great for a couple of months now. I pruned some old backups of vm/102 that were corrupt, and now when I look at my datastore, most of the groups have Verify State with a Yellow "All OK (old)" indicated. See screenshot below.

I have tried manually starting the Verify job, but it just runs and says "Success" but the column stays yellow.

How do I address this warning please? Is there a way to kick off a "full" re-verification, either...
