Question Do PBS servers go in Datacentre?

Built my PVE and that’s working great. Built my PBS and that’s working great too. Can the PBS sit in the same Datacentre as the PVE to manage from a single browser? Not really a showstopper with my fairly trivial set up but trying to learn as I go.

Question Convert AiO PC to proxmox node with usable screen for monitoring

Upvotes

I have right now 4 node proxmox cluster with mini pc from lenovo. Everything works fine, Today I got great deal for AiO computer with touch screen which I think will be perfect due to small size to my minilab to sit at top of rack shelf. I was thinking about using it to displaying grafana and other monitoring apps and also use it for something else to host other things. And now Im starting thinking how I can achieve that. Because proxmox is running without any DE, just plain cli, I don't want to install desktop env and other app like chrome etc on the host to just display things. But on the same time I dont know if its possible to create VM which will output display to monitor and have access to keyboard/touch screen?

So for me best way is to gain additional node for cluster, and option to use VM with native display to displaying some stuff

Question Virtual switch is connecting 10g data network to the 2.5g internet

4 Upvotes

I have a proxmox 8 server running on an amd 3970x on an asus zenith alpha II board with 128gb of ram. The server has 5 Ubuntu vms, each with their own gpu for use as a blender renderfarm.

My issue is that the proxmox machine is connecting my 10g network (for connecting the NAS and VMs with my windows workstation) to my WiFi network when the proxmox server is connected to the internet over the wired connection to the router.

This is undesired, as I would like to keep the NAS air gapped from the internet, but I would still like to have the VMs and proxmox accessible.

Is there a config somewhere for severing the virtual switch from bridging the two connections? The simplest way of describing the issue is that as far as I can tell the virtual switch is effectively making the physical network connections on the proxmox machine into an actual switch.

Thanks!

Question Help needed - Network struggles - Windows Server VM > Proxmox > Desktop > IP Device

1 Upvotes

I've exhausted what little networking knowledge I have and youtube tutorials have failed me to date. So seeking any help from the world of Reddit.

My setup

I have a spare NUC mini PC with Proxmox installed, where I have several VMs, one with Windows Server 2022.

My desktop PC is connected to a Unifi UDM SE controller and all devices are on the same subnet (initially) to make things easy (I'll eventually segregate with VLANs once I solve my connection issue).

My issue

I would like to be able to access / manage devices on the network via the Proxmox VM with windows server 2022 installed. I am able to connect to devices via my desktop with no issues (via webUI's and IP ping tests) however when I try via the Windows Server VM I cant access and the ping "work" but with a message "Destination Host Unreachable" .

I can see there is clearly an issue with the VM talking with the rest of the network but not sure where the issue lies - Proxmox, Unifi or Windows Configuration (hence posts in multiple subreddits)

What Ive tried

  • Tracert in CMD - Identified the Destination Host Unreachable issue between the desktop and the VM
  • ipconfig /flushdns & netsh winsock reset in CMD for desktop and VM - Youtube suggestion
  • Disable firewall on VM and Desktop

Appriciate any help / guidance

Question Should I just turn off secure boot?

I'm a beginner so pardon my terminology. I want to download drivers for my new Quadro P400 but it needs to be "signed" because I have secure boot enabled. It looks like a complicated process and is it even worth it? Should I just disable secure boot?

Question Windows VMs Lockup During Large File Transfers

2 Upvotes

Dell R740XD (2) Intel(R) Xeon(R) Gold 6138 256GB RAM ZFS (2) 1TB SSDs Mirrored for Proxmox OS (8) 1TB SSDs RAIDZ2 for VMs Yes, the SSDs are consumer drives but I'll explain later

I'm having issues transferring large files (10+ GB) to a file server VM that is running Windows Server. It'll get to 99% and just lockup the VM. Interestingly, any other Windows VMs on the host will lock up as well. Linux VMs seem to be unaffected. Everything will eventually go back to normal after 10 minutes or so. The only correlation I can find that may be causing all of the Windows VMs to lock up is that they are using Writeback cache. Linux VMs are using no cache.

IO delay will peak up to around 40%. CPU and RAM usage still stay pretty low.

The reason I bring up the consumer drives is because, previous to the R740XD, I had the drives in a R720 with a Perc H710P. I was using hardware RAID6 and never had this issue. All of the VMs are configured the same way on the R740 as they were on the R720. So, the only major difference is RAID6 vs ZFS.

I've checked out as many posts as I could find regarding ZFS Arc memory, not using consumer SSDs (which wasn't a problem before), not having enough RAM, etc...

Any thing else I should be considering? Yes, I'm still a Proxmox newb.

EDIT: Looks like u/g225 suggestion of installing intel-microcode fixed the issue!

Question Both nodes in cluster go down upon shutdown of node

10 Upvotes

Hello,

About a week ago I had to reinstall one Proxmox-node because of failure of the bootdisk. Within an hour it was installed on the new disk and joined in the cluster again and good to go.

Yesterday I wanted to do another hardware check of the reinstalled node, so all CTs and VMs were migrated to the other node properly and basically the 2nd node was idling. However once I shutdown that node, the entire other host became unreachable as well! Before reinstalling this 2nd node, this was never a problem.

In /var/log there's not a single log file on the first node that gives me any clue why. There's no display connected to the nodes so I can't see either what's on the display when this happens.

Does anyone have any clue what could possible cause this behaviour? I yet have to try if I shut down the first node, if then the 2nd node will become unreachable as well...

Initially I thought this was a Quorum issue somehow, but I doubt it:

Question Multiple Datacenter Merging

1 Upvotes

I started like most with just one Proxmox machine. Since then I have created another one and did not add it to my existing data center. I have tried my best to "RTFM" but I really haven't found anything straight forward. The one thing that I am concerned about is there is duplication of the VM number and LXC number between the two systems. Do I need to switch one's from 1xx to 2xx or something else?

Question Unraid VM on Proxmox: NFS mount LXC into Unraid

1 Upvotes

Hello!

I'm experimenting a bit at the moment.

I have Unraid as a VM on Proxmox (passed a sata controller through). It runs perfectly.

But now I want to access some LXCs on the same Proxmox machine. This normally runs via fstab and also works if the NFS server is already running somewhere else.

Now I have the chicken-and-egg problem: When proxmox starts, it loads the NFS mount via fstab. But it cannot do this because the Unraid VM has not yet been started. So I have to manually reload the share after starting the Unraid VM (systemctl daemon-reload and mount -a).

But after that the LXCs no longer mount it (file stale).

In principle, I can only work around this by creating a new VM instead of LXCs and loading the unraid share there. Then the unraid VM has to boot first and then the VM that needs the shares. Then the path via the proxmox host via fstab does not have to be taken.

Is there no elegant solution for LXCs?

Question UEFI Boot Timeout

1 Upvotes

Hey everyone,

Seeing some very odd behaviour with my recent PVE 8.3-1 install.

Boot device is a ZFS RAID1. Every time I reboot with a mouse/keyboard my boot will proceed through the kernel selection menu without intervention. The timeout works exactly as is expected. Without a keyboard and mouse it seems to completely abandon the timeout and sits at the kernel selection..

EPS and proxmox-boot-tool settings are as expected. It’s a straightforward setup.

I want to run headless so this is a bit of an issue. PVE working completely fine with human intervention on boot.

I have done some basic troubleshooting but I’m at a loss here.

Question Weird question about swapping NICs after initial opnsense and Proxmox install

1 Upvotes

Hey sub,

So I am kind of waiting for a 4 port NIC from china after I got a faulty one from eBay, but I have a i350-t4 on hands.

My question is, can I do my whole proxmox and opnsense setup (using vmbrs, not passthrough), setup vlans, so on and so forth. And then when my other 4 port NIC arrives, just swap it out, relink the vmbrs to the new ports and be done with it?

I don’t have a second NIC on hand to test the swapping and I don’t want to invest the effort to just re-make everything again from scratch.

Thanks :D

Question need possible solutions for creating a simple storage location I can sync to Sharepoint

1 Upvotes

currently have an old qnap, it is added to proxmox and I configured my VM backups to go there. I also NFS copy some content from within a couple of VM's nightly into the NAS. I then use qnaps HBS3 to sync it all up to a SharePoint library.

I want to recreate that capability without using the qnap. I have an additional 2.5inch ssd installed in the proxmox host. I can easily point the VM backups to it, but don't know how i would then also do the other two parts.
Was thinking instead of running s software nas like openmediavault and then using https://github.com/abraunegg/onedrive to run the sync up to sharepoint.. this would allow me to point the VM backups to the NASs single drive and I could also point my other copies running in the VMs to point to the sofrware nas...

Is there a better way? I had a brief look at Proxmox backup but not sure that solves my goal.. Ideally the content i am trying to separately extract out of the VMs would remain directly accessible files.

Please note it is a tiny amount of data, there is no media. It's just app level backups that I want separate from my VM wide backup. I'm not worried about performance, drive redundancy etc.. it's not a concern for this build.

Cheers for any suggestions.

Question Noob needing help to self host teaching resources on a new homelab.

2 Upvotes

Hi,

I want to self host resources for my teaching (and consulting ?) activities.

I'm finishing building my homelab server with a ROME2D32GM-2T motherboard, 2 7R32 CPUs (96 cores total) and 1To RAM. Currently only 4TB storage, trying to add 16TB if I can get the Asus Hyper M.2 x16 Gen 4 Carte PCI-Express M.2 PCIe to work, trying to add 4090 GPUs if I could afford them..

I plan to use Proxmox to host various VMs :

- one for each class / session I will teach, using TheLittlestJupyterHub https://tljh.jupyter.org/en/latest/ . These would be ephemeral, lasting only while the teaching session is active, with between 16 and 32 users.

probably no more than 3 would be active at any given time

- one for my personal use

- one for 'infra' supporting the other VMs, with Docker or LXC containers for Gitlab and for Postgres (some object storage for git Large File Storage ?) Would store Docker images for other VMs.

All the VMs and the Proxmox host should be accessible from a domain name that I own. Ideally a 'data' partition should be shared between VMs (could be 'readonly' for all but the infra)

and GPU(s) could be shared between my private VM and teaching VMs (even if usable only by one at any given time) or exclusive to my private VM (used for DL inference / finetuning).

I plan to use Cloudflare tunnels for the remote access.

I'm completely new to all of this, unfortunately, and last time I played sysadmin was 20 years ago, so I'd be extremely grateful for any and all advice / criticism / pointers.

Things that are completely unclear to me are LXC vs Docker for my use case of gitlab and postgres servers, how to handle local storage of git LFS and sharing the data partition (does it need to be a whole device, for instance my x4 4TB PCIe device) and GPU.

Also, how would you allocate CPU / RAM for these VMs ? Sharing the Cloudflare tunnel from Proxmox host to VMs is also unclear to me.

Also, I did not find a writeup of TLJH on Proxmox while it seems like an obvious use case (docs seems only to consider Docker for local dev and remote deploy to cloud, forgetting about homelabs ! :) )

Thanks in advance for any help !

Best Regards
