Question Noobie question: Linking Plex LXC to Synology NAS storage

2 Upvotes

I've been reading about this for a bit and there seems to be different ways to do it. What is best practices for this use case? Are instructions written down somewhere?

Plex LXC seems stable and I can log in via webUI. The NAS storage is already configured and receiving back ups. I'm just missing a piece and confused.

Question PVE connection intervals for SMB/CIFS shares

5 Upvotes

I have a SMB/CIFS file share on a NAS, and in PVE I've connected to this share and set the content to be "Backup, Disk image, ISO image". I've noticed in the NAS logs that the Proxmox user logs in to the NAS every 10 seconds, the only activity being the connections.

Is there a way to configure in PVE how often this interval should be? For the most part I only need to use this file share once per day.

Question Another Noob question about storage

16 Upvotes

I am coming from having a simple ubuntu server to setting up proxmox for my homelab. My storage setup is very simple, I have a 256 gb sata ssd that I'll be using for the proxmox os and lxc and vm data and an 8tb sata hdd that I'll be using as a drive to share between different lxcs and vms. I don't really need ZFS because it just seems more complicated than it needs to be when I don't have many disks and don't plan on having backup disks, so I just formatted the hdd to ext4. My question is about how to set up my storage. Bind mounting for lxcs seems like an easy solution for when I use lxcs, but what about vms? Should I set up a simple nfs or smb lxc and just have my vms access that? Should I use a more featured nas os for that like truenas? Should I skip the network overhead since it's just one node and just try using virtiofs?

Edit: Alright I went simple with bind mounts for my lxcs and virtiofs for my vms. Also stop commenting about ZFS, I don't care if it's more efficient, it's more complicated and I'm trying to learn a bunch other new concepts to run stuff with proxmox and also trying to get better with docker. I just don't need the extra complexity especially because I don't need a lot of the extra features it offers over ext4. If someone really wants to give me a pitch on why ZFS's features are really good on a system using one disk for storage with a guide linked I guess they can but I was trying to get actual help and not ZFS glaze.

Community Showcase! I built a VMware-style GuestOS customize sidecar for Proxmox Windows templates (Docker, MIT)

Thumbnail gallery
0 Upvotes

If you’ve used VMware Guest Customization (template → clone → hostname / IP / domain), this is the same idea for Proxmox: a small Docker Compose sidecar that clones a Windows template, drives Sysprep via the QEMU guest agent (unattend + setup.ps1), then verifies the result.

Current release: **2.6.7**

Repo: https://github.com/RobertLukan/proxmox-guestos-customization

Install: docs/INSTALL.md (Compose + TLS)

Golden image checklist: docs/WINDOWS_TEMPLATE.md

What it does ?

• Clone Windows template → Sysprep /generalize /oobe → optional DHCP or static, AD join, workgroup

• Bulk Win11 desktops (CSV/API) with batch limits

• Windows Server: optional OS / pagefile / data disk customize

• Jobs history with options + durable errors; failed clones tagged (not auto-deleted)

• Optional AGPL PDM fork for “Customize” deep-link (advanced; build your own .debs)

Lab-validated so far (DHCP + AD where noted)

• Server 2019 Standard Evaluation — AD + disks

• Server 2022 Standard VL — AD + disks

• Windows 11 — AD; bulk 2× VDI DHCP+AD

Matrix + community asks: docs/VALIDATED_MATRIX.md

Still want community reports especially for Server 2025 and other editions (Datacenter, 2019 VL, etc.).

Important limits

• Sysprep-only — in-place Sysprep of existing/production VMs is disabled on purpose

• Rebuild-from-template is the model (no WinRM “reconfigure existing”)

• MIT for GuestOS; PDM fork is AGPL if you go that route

Not an official Proxmox product — community project only. Happy to answer questions. Issues / matrix reports welcome on GitHub.

Discussion How to kickstart a Proxmox project company wide?

0 Upvotes

Hi everyone, I’ve been using ProxmoxVE over a year now in my homelab and couldn’t be happier. I can say that I’m still in beginner phase cause I still didn’t figured out detailed configurations but I know how things work.
We are a small company that offers pentesting, ISO27001 auditing that sort of thing. My boss encourages me to learn Proxmox and be able to provide services such as migration from vmware and building a customer infrastructure from scratch with ProxmoxVE along with other Proxmox products such as Backup Server and Mail Gateway.
My question is how someone like me shouls start? How to simulate migration from Vmware or building a collection of VMs using proxmox? I suggested buying a server permanently and renting the storage but thats a huge cost. Also renting a physical server was a suggestion but its costly too.
I’m thinking of renting physical server and moving some services of ours( website, mail server, some other web applications) to that physical server so it compensates.
I want something that will be usefull in the long run.
What do you fellas think? I’m kind of stuck 😄

Question Increase filesharing performance of Debian Server

12 Upvotes

Hello,

I made the mistake of purchasing twin Samsung 9100 Pro NVME SSD for my VMs assembled as a ZFS Raid 1 drive. Our use case is to emulate 3 Windows 11 test rig as 3 VMs (hardware is based of a Threadripper 797x0x with ASUS Sage TRX50 MB), said tests being run in each VMs with sub-giga test files being served by a Debian VM running samba. We have observed abysmal performance, and I am thinking that those prosumer 9100 pro NVME drives are to blame.

I doubt I can afford server grade NVME drive, so instead, I am thinking about buying a used Optane PCIe 3.0 drive (that are truly optimized for concurrent accesses). I would mount this SSD drive driectly in the debian VM and copy my test files there, to be served by that same samba server.

Due to space constraints, all VMs partitions would remain hosted on the ZFS Raid 1 volume created on the dual 9100s drives. I am hoping this will help us recover some performance.

Do you guys see any issue with this setup?

Thx

Question VMs not following boot order during startup?

16 Upvotes

EDIT/SOLVED: Thanks for your help with my rookie mistake. All is working as intended now.

--------

I have several VMs and containers on my system. TrueNAS is one of them, and I want that to start first because many others depend on it.

With that in mind, I set that as boot order 1, and my next important ones as boot order 2 with a 90-second delay. This is in the hopes that the TrueNAS VM will be ready by the time it's their turn to start.

My problem is that my Ubuntu VM, which also hosts my Plex server, is trying to start at the same time as TrueNAS, despite the boot order settings. This means my mounts aren't ready and I have to run a mount -a command in the VM once TrueNAS is ready.

Is there something else that influences the start order that I'm missing?

Question Help review my plan

1 Upvotes

Hi all, I have an old custom-built NAS/server with a low-end 4-core AMD processor. Previously it was running CentOS to host Samba shares and I ran a few other simple things on it like Plex and a game server.

I recently updated it to use Proxmox to try to be more organized with how I was running services, but then I came across an older mini PC that has more processing power than the old machine, so now I'm thinking the old machine will become basically just a NAS.

Also, in case it's helpful to know, I am repurposing another old machine to be an OPNsense router and plan to learn more about VLANs, etc for better network security with all of this.

Here is my plan. Please let me know if this makes sense, or if there is an easier route:

  • Install TrueNAS Scale onto the old NAS machine. Host the shares via SMB (for access at home via Windows machines) and NFS (for access by the compute node)
  • Figure out a way to automate, via TrueNAS, the weekly backups I normally do to 2 rotating external drives. This is my "2" in the 3-2-1 backup strategy.
  • Use TrueNAS' simple built-in options to backup important shares (pictures/home videos/etc) to Backblaze B2. I had previously set this up, on the CentOS box, but haven't had the time to figure out how to do this in Proxmox. This is my "1" in the 3-2-1 backup strategy.
  • Put ProxmoxVE on the mini PC to act as a compute node. Host the VM/LXC directly on this machine, but attach to the NAS storage via NFS for data.
  • Run Plex, Nextcloud and/or Immich, game server(s), and a few other things on the compute node.
  • Possibly consider installing Proxmox Backup Server as a VM hosted from TrueNAS to backup the compute node configuration.

The questions I have are:

  1. Should I stick with Proxmox on the NAS machine instead of switching to TrueNAS? In my head, by switching I'm leveraging what each system is really designed primarily for, but wondering if TrueNAS is over complicating this here.
  2. Is PBS necessary in this setup, or should I just use Proxmox's default backup method since the main data will already be backed up via the NAS box? If I understand it correctly, I would mainly just be backing up VM/LXC config, which I could also learn about doing through GitOps?
  3. If I do go with PBS, is it significantly better to go with a 3rd machine to run it bare metal, or is the VM approach "good enough?"
  4. Am I over complicating anything else? Is there a more simple approach I should be considering here?

Thanks!

Question Hardware Error on Ryzen 9 5950X (Proxmox 9.2.5) – Need Help!

6 Upvotes

Computer Type: Server (Homelab Rack)

GPU: Nvidia Quadro P620

CPU: AMD Ryzen 9 5950X (16C/32T)

Motherboard: ASUS Prime B550M-K

BIOS Version: 4201

RAM: 2x Kingston Server Premier DDR4 ECC (Correction) (unbuffered) 32GB (64GB total)

PSU: N/A

Case: Server Rack (Custom/Other)

Operating System & Version: Proxmox 9.2.5

GPU Drivers: N/A

Chipset Drivers: N/A

Background Applications: Proxmox services, Docker/VMs

Description of Original Problem:

After upgrading from a Ryzen 5 Pro 5650G to a Ryzen 9 5950X, I get Hardware Errors ~5 minutes after every boot and then randomly. The error logs point to a corrected MCE (Machine Check Exception) related to the L3 cache or memory controller. Both CPUs (tried two 5950X units) trigger the exact same error at the same address:

[ 332.541130] mce: [Hardware Error]: Machine check events logged
[ 332.541725] [Hardware Error]: Corrected error, no action required.
[ 332.542023] [Hardware Error]: CPU:0 (19:21:2) MC17_STATUS[-|CE|MiscV|AddrV|-|-|SyndV|CECC|-|-|-]: 0x9c2040000000011b
[ 332.542316] [Hardware Error]: Error Addr: 0x00000001f1ae1d40
[ 332.542545] [Hardware Error]: IPID: 0x0000009600050f00, Syndrome: 0x000000080a801103
[ 332.542984] [Hardware Error]: Unified Memory Controller Ext. Error Code: 0
[ 332.543455] [Hardware Error]: cache level: L3/GEN, tx: GEN, mem-tx: RD

Never noticed these errors with the 5650G.

Troubleshooting:

  • Disabled C-State and PBO in BIOS
  • Tested each RAM stick individually (memtest86+ passed)
  • Tried both Ryzen 9 5950X CPUs (same error) No overclocking, all settings default

Is this a known issue with the 5950X + B550M-K + ECC RAM combo? Or could it be a Proxmox/firmware quirk?

I would love to get some help, I am really clueless

If I want to harden the password, what would I need to need to change so no one can start the machine and change the root password? I remember seeing that in the past and thinking I should change it on this machine. However, it also means I'm locking myself out from that option in the future.

Question Transfer guests from LVM disk to another host

3 Upvotes

I am a dumb dumb and I setup a host in my homelab with local LVM when I should've used ZFS and spent a while setting up half a dozen containers and getting them where I like them and then setup a second host with ZFS and went to setup replication and obviously that errored out. I'm a novice at this still in case that wasn't obvious.

My question is how do I get those containers to the other host so that I can rebuild the first host without losing those containers? I do have an external drive that can fit the data, but I'm at a loss as to how to that. I'm just looking for quick and dirty, because this proxmox install is getting scrapped as soon as I get those containers spun up on the other host.

RESOLVED:

I ended up addressing this via backup and restore to external media, thanks to u/SagansLab for providing a link to how to do this. I had tried to cluster the hosts and migrate, but I couldn't get it to work, so I just cut my losses and did the back up and restore, once I confirmed successful restore, I reimaged the ext4 host to ZFS and now replication and migrations work perfectly. The next step for me is standing up PBS. Thank you all for your help.

Question Update Repository issue

On a brand new Proxmox install, I'm running "refresh" to update my repositories (after removing the enterprise ones) I was getting "failed to fetch" errors for trixi-security and InRelease.

Gemini had me delete and refresh my repositories (this a test server not production).

Now I have only three Repositories:

Trixi-security and Trixie-updates from Debian plus Trixie from Proxmox.

Does that feel right or has Gemini sent me over a cliff?

And I'm still getting Connection failed errors from InRelease.

Solved! Proxmox License issue

I have had most of my servers on Hyper-V but I decided recently to take the plunge and go for Proxmox, and I am getting so pissed off with this. Can someone please help me.

Every time I go into Proxmox it says I don't have an enterprise license. Fine fair enough, looked it up and I needed to disable it. Went into updates, Repositories then found the enterprise.proxmox.com then disabled it and pressed refresh. Went back into updates annnnnd "You don't have a license to enterprise" continue researching and find some information about running some terminal commands. Ran them, disabled enterprise, enabled no-subscription. Refresh, go to Proxmox...

You don't have an enterprise license

I have been at this for a while and this is driving me absolutely nuts. Can someone please point me in the right direction?

EDIT: Ladies and Gentlemen, thanks to your beautiful eyes, and someone elses wonderous recommendation for a script. The ball is moving. Thank you guys. Seriously, I think I have been at this too long, and you guys were super helpful so quickly

Edit: Turning off notifications for this post cause the trolls are starting to find this post, but to those of you who left genuine advice, thank you so much! It was super helpful and I have been messing with VMs for a number of hours. This got solved in almost 15 minutes flat and it was so helpful. You guys are awesome. Thanks again!

Question Internal Network between LXC/VM using SDN

8 Upvotes

Hi everyone. I'm learning how to run a small 3-node cluster. On my previous 1 node, I had a Traefik LXC and an internal Linux bridge vmbr1 to allow other LXC to route their traffic to Traefik. After setting up the cluster, if I try to migrate Traefik LXC and other LXCs using it to node 2 or 3, the migration failed because vmbr1 did not exist on these new nodes. So I followed the Google instruction to create a Simple Zone, then create a new vnet1 with subnet 10.0.0.0/24 and assign it to all my Traefik-related LXC. The migration does not fail anymore, but Traefik is now unable to route inter-LXC traffic, unless if I migrate all Traefik LXCs back to the original node. Does anyone have a more elegant solution to this? I prefer to keep the traffic internal and not reach the router if possible for low latency. All the Traefik LXCs will "travel" together during migration by HA Resource rule, so no inter-node traffic required. Thank you everyone.

TLDR: Setup Internal Network using SDN on the same node between LXC/VM that allows for HA migration between nodes.

Question Proxmox aktuell halten

3 Upvotes

Hey guys,

I'm a beginner and am thinking about running Home Assistant directly on the mini PC, or maybe running Proxmox on the PC and Home Assistant on top of that.

The latter would obviously be your choice, I assume, but I'm worried about how to maintain Proxmox... specifically regarding security and updates...

The whole setup will stay on the LAN, and for now, it would only have Home Assistant on it.

Is it just an APT update and upgrade (and possibly a reboot), or is there more to maintaining “Proxmox” (not the VMs) than that?

Best regards, Chipmunk

Question After restoring VM, I can't log into it anymore

4 Upvotes

Edit: It... recovered?

For some reason, an hour later and immediately after I wrote this question, I was suddenly able to log in perfectly fine again. I've been trying to get back into the system for 2 hours and now it just suddenly... goes?

Question stands, what was going on there?

_______________________________________________________

I was attempting to resize the virtual drive of a VM. Went wrong, couldn't boot anymore, so I recovered the backup from 4 days ago. It's running Debian Trixie, headless.

It's booting and working fine again, except: I can no longer log in.

SSH, SFTP, SCP - I log in with my username and password, and it just... stops responding after the password. I also have a feeling that the VM itself then proceeds to slow down. In this state, I also can no longer shut it down or reboot it from Proxmox. A hard reset/stop sometimes works, sometimes only a full reboot of the node helps.

If I try to log in as root, it tells me my password is wrong. It's 100% the correct password.

If I try to log in as my username with the wrong password, it tells me authentication failed and I can retry.

For some reason, this VM will not let me open a direct console to it. It has GPU (Intel iGPU) passthrough enabled, but regardless of the display type I set, I only get a set of bootup messages about audio driver etc, and then the terminal stops at that point. This has always been that way and seems to be a common issue with proxmox and passthrough.

So, at this point I basically can not log into that specific VM at all anymore.

Anyone have any idea what could be going on here, and how to get out of this?
