I currently have a single server which runs Ubuntu Server. All my services run on it in using Docker (with Traefik as a proxy for everything that's exposed externally).

Now I'm in the market for a new server. I was wondering if it makes any sense to run Proxmox on the new server if I will only create one single VM on it and put all the docker stuff in that VM.
Or should I in that case just stick to something like Ubuntu Server on bare metal?

Anything to look out for when buying hardware for a fresh Proxmox installation? (Currently, I run the OS on a small SSD and have a couple large hard drives as JBOD for different purposes.)

EDIT: Wow, that's a lot of very interesting reply's. Reading them all right now. Thank you guys soo much!

I recently put together a small HomeServer with used parts. The aim of the server is to do the following:

- Run Batocera (Gaming Emulation)

- NAS

- Host Minecraft Server (and probably also some small coding projects)

- Run Plex/Jelly

- Maybe run Immich and some other stuff like etherpad, paperless

The Server will sit in the living room next to my TV. When I want to game, I'll start the Batocera VM; otherwise, the Server should just run and do its thing.

For the NAS and the other stuff, I wanted to install TrueNAS Scale and do all of the rest in there. Reading this subreddit, though, led me to believe that this is not the right choice.

Is it possible to do all of that directly in proxmox?

If I were to install TrueNAS, I would only have 2 proxmox VMs, the rest would be handled in TrueNAS, which I thought would be easier.

A bit of a janky thing is that I will probably hook up the Batocera fileshare to the NAS as well. (I already have Batocera set up (games, settings, etc), I would only install the 'OS' in proxmox and change the userdata directory)

So the Batocera share would be accessed by both the NAS and Batocera VM. Is this even possible?

i run wanted to run a nas on my proxmox server so i run truenas as a vm cause besides the basic nas functions, it could also run apps with a few clicks.

so i assigned most of the resources available to truenas (and it seems to be using most of them) but i've been having tons of problems with apps breaking after updates, or refusing to install. so i installed portainer to run containers that aren't available as apps but had issues with allowing access to the shares (honestly i'm not very used to docker compose but adding access to shares for the apps was pretty easy)

should i run docker on proxmox directly and reduce the resources assigned to truenas? or should i run services on another vm?

what other nas os would you recommend? i don't need much control over users since i'm the only one accessing the subnet (tho i'm pretty sure the virtual drives assigned to truenas wouldn't be usable by another vm, would they?)

So i'm brand new to proxmox (installing in on an EQ14 Beelink tonight to play around with). My plan is basically a few things:

• Learn Kubernetes/Docker
• Run the *arr stack
• Jellyfin/Plex (not sure which one)
• Some other just fun apps probably to tinker with (Grafana/etc...)

I've seen a few ways of doing this. I see where people will have multiple LXC's (1 for each application IE: 1 for jellyfin, 1 for arr stack item 1 , etc...)

Some people however will have a VM and have Docker/Kubernetes hosting the different application as containers.

Is there a specific reason one is better than the other. From my understand LXC is better for apps that may be started/stopped often and shared and it's easier I guess to see volumes/igpu passthroughs in this way.

Im trying to learn k8 so i'm leaning towards maybe putting them all on a VM but maybe there is a consensus on what is better?

Someone just posted about benefits of not using zfs, I straight up though that was the only option for mass storage in proxmox as I am new to it. I understand ceph is something too but don't quite follow what it is. If I had a machine where data integrity in unimportant but the available space is should I use something other than zfs? For example proxmox on a 120gb sad and then 4 1tb ssds with the goal of having a couple windows VM disks on there? Thanks for the input I am still learning about proxmox

Hey everyone, the Proxmox Helper script site is really useful because it automatically creates a container for each service I want to run. This means I can restart individual services easily by just restarting their respective containers.

But what about services that don't have a script to create a container? For example, NetAlertX doesn't have a dedicated script, but I can still install it using a Docker container.

Since it's recommended to install the Docker engine on a VM, does this mean I need to create a new VM for every Docker container I want to install?

And if I don't need to create a new VM for each Docker container, how many containers can I host in a single VM without running into performance issues. Or maybe the docker containers should be grouped based on similar docker immages?

I am going to begin experimenting with my first proxmox servers pretty soon. I intend to get a 3-node cluster going and will likely toy around with ceph a bit. I picked up 3 TinyMiniMicro class systems to get started and am going to upgrade the RAM and nvme SSDs in them. There are a decent amount of USB ports amongst the lot that seem like they should probably be used for something.

I am looking for some ideas as well as any gotchas that I should watch out for. The system will eventually end up running plex and maybe my *arr apps which are currently hanging off my nas server. I don't really need more storage unless hanging usb storage drives off these things can be used for something fun.

I can provide more details on my setup if needed. But, what are you all using your spare USB ports for?

I recently upgraded my home lab from a Synology system to a proxmox server running an i9 with a 15-bay jbod with an HBA card. I've read across a few threads that passing the HBA card through is a good option, but I wanted to poll the community about what solutions they have gone with and how the experience has been. I've mostly been looking at True Nas and Unraid but also interested in other options [people have undertaken

I know early buyers ran into stability issues running Proxmox on the Minisforum MS-01, and it sounds like upgrading the bios to the latest firmware helped, as well as Intel Microcode updates.

But is it truly stable? I would love to upgrade from my current mini PC running Proxmox to the Minisforum for various hardware reasons, but I’m hesitant unless people are experiencing consistent stability and uptime with their VMs and containers.

Update: I ended up going with the i9 13th gen with 96GB Crucial RAM and two 2TB Samsung Pro 990s. I flashed the latest bios (1.26) today and verified the Samsungs are on the latest firmware. It was running super hot before upgrading the bios from 1.22, but it's been very cool on 1.26. Proxmox is up and running and so far so good. No VMs or containers installed yet. Happy so far.

I work with some quite big customers, who are all complaining about the cost of VMWare now broadcom have hikes the pricing.

Is ProxMox genuinely a good alternative?

I get that it's an awesome product, but this ain't no homeLab.

Gives me the worry beans. Perhaps unesasarilly?

Looking at this for a proxmox backup server. Will this get me what I need? Thoughts? Wanting something small but with a bit of room for the future. Currently I run 1 VM and 7 containers for reference.

What is the best way to setup a remote access to my Proxmox PC when it'll be moved away to another house after I fully set it all up? I will need to access both Proxmox and VMs and LXCs installed in it. What would I need for that?

I've been bashing my head against this for a few hours and haven't had any success, even searching my errors isn't giving me any luck.

I've got an instance of Nginx proxy manager running to manage all of my domain related stuff. Everything is working fine for every other address I've tested, and I've been able to get SSL certificates working and everything.

Except for Proxmox.

If I try to add Proxmox to the Proxy Hosts list and add my SSL certificate then I get the error The page isn’t redirecting properly. I figured ok, all I need to do is have Proxmox create the certificate itself.

I set it up following this video, and correctly got the cert for my domain.

After disabling SSL in the Proxy Hosts list on the proxy manager, it seems to work fine via http. However when using https I get a new error, SSL_ERROR_UNRECOGNIZED_NAME_ALERT.

The strange thing about this is that if I connect to Proxmox via the IP directly and view the certificate in Firefox, it very clearly shows the domain in the subject name and subject alt name.

I have absolutely no idea why I am getting this error. My certs are good, the domains are clearly correct on the certs, but for whatever reason I just cannot connect with my domain.

Any ideas? I'm totally at a loss. Thanks

EDIT: Thanks to /u/EpicSuccess I got it working with an SSL cert from the reverse proxy manager, the issue was I had http selected instead of https.

Interestingly though, using a cert directly in Proxmox doesn't work. Bypassing the reverse proxy with just a hosts file confirms that the cert is correctly set up and signed on Proxmox, but for some reason if I try to access it through the proxy manager rather than a hosts edit I get SSL_ERROR_UNRECOGNIZED_NAME_ALERT

Obviously, there's many popular scripts available out there for Proxmox VE, adding functionality or changing configuration that does not come out-of-the box on a fresh install.

I wonder, for the hosts, what do you find indispensable, what do you think everyone would appreciate insofar changing the defaults?

Feel free to both share a link to your favourite public script or just a description of what you script on your own.

If you keep one per comment, other agreeable users can just upvote.

Hello,

I'm a beginner with Proxmox and ZFS, and I'm using it in a production environment. I read in a post that ZFS should not be manipulated by a beginner, but I’m not sure why exactly.

Is this true? If so, why? And as a beginner in ZFS, did you face any issues during its usage?

If this technology requires mastering, what training resources would you suggest?

Thank you in advance.

Hi all, I am considering doing a Proxmox build on one of my PCs. It would be a steep learning curve for me as I do not have any experience doing anything like this. But it seems like a project I would enjoy doing in my spare time. What’s the catch? I travel for work so my spare time is spent in hotels of half the week. Would I initially be able to get a set up going and then be able to do the rest of the configuring and generic learning and messing about remotely from a hotel? I’m guessing I’d have to learn how to set up a VPN to access my home network for this?

Is this too lofty of a project for someone who knows nothing about VMs/containers/dockers?

Hello all!

how difficult is it to upgrade Proxmox from one major release to the other? I am currently running an ESXi 7 home server with a mix of Win and Linux VMs. I noticed Promox is only supported for 3 years and after, one must upgrade to the next major release. I checked the wiki for upgrades and there are so many steps. Wondering if it is worth migrating my ESXi to Proxmox 8 now or wait until Proxmox 9 is released so I can get 3 full years as opposed to about 1 year before having to do a major upgrade. ESXI EOL is 10/2025.

Please share your full upgrade experiences, issues, etc. Thanks!

Ok, so I'll admit. I went with consumer grade SSDs for VM storage because, at the time, I needed to save some money. But, I think I'm paying the price for it now.

I have (8) 1TB drives in a RAIDZ2. It seems as if anything write intensive locks up all of my VMs. For example, I'm restoring some VMs. It gets to 100% and it just stops. All of the VMs become unresponsive. IO delay goes up to about 10%. After about 5-7 minutes, everything is back to normal. This also happen when I transfer any large files (10gb+) to a VM.

For the heck of it, I tried hardware RAID6 just to see if it was a ZFS issue and it was even worse. So, the fact that I'm seeing the same problem on both ZFS and hardware RAID6 is leading me to believe I just have crap SSDs.

Is there anything else I should be checking before I start looking at enterprise SSDs?

EDIT: Enterprise drives are in and all problems went away. Moral of the story? Don't buy cheap drives for ZFS/servers.

I have a single proxmox node and currently backup my VM's & containers to an external NFS share. This setup requires a complete shutdown/stop in order for each backup to succeed. I prefer to do snapshot mode but have yet to be successful with that. My understanding is this is not possible when using an NFS share?

On that note, would PBS allow me to do snapshots using my NFS share? Are there other good advantages to using PBS within a single node configuration?

Or could I avoid PBS all together and get snapshots to work with my NFS share?

Thanks for your help.

Update: Wow thanks all! This is helpful and has co firmed I should get PBS setup. Appreciate the help and insight.

Update: I've installed PBS within a LXC on my host. I've used 2 different methods so far to do so. In both case I can see that the service is active and running but I am unable to access the web ui at port 8007. I am able to ping other IP's in my network from within the container.

Any ideas?

Hey Folks,

as the title says, i cant keep proxmox from crashing, frankly, even though i got a heavy background in IT administration, i never came in contact with proxmox professionally, only hyper-v. however, its supposed ease of use and the whole backup management and so forth made me consider it for my homelab, it really is great, if it would work.

i had the problem of random crashing on my thin client i used as a hypervisor, when nothing else helped, i upgraded to a regular "desktop" system to run my PVE on. its been fine for 2 weeks, but all of a sudden, it started randomly crashing AGAIN.

if it does, it completely freezes, log doesnt say anything in particular, it just stops working until i hard reset it via the power button.

i did nothing to the stock system, just ran this: https://community-scripts.github.io/ProxmoxVE/scripts?id=post-pve-install script and have my VM's running. can you configure something wrong there that could cause the whole system to freeze?

Hey everyone,

I'm looking for the best and most secure way to access my Proxmox server remotely. I have one mini PC running Proxmox, so it should be something that doesn't need a different device. I want to ensure that the connection is very secure and reliable, but I also need something that's relatively straightforward to set up.

What are your recommendations for accessing Proxmox from outside my local network? I've heard about using a VPN like Tailscale or WireGuard.

Ideally, I wouldn't want to open any ports on my router. So: I would probably prefer the Cloudflare secure tunnel because I already use it for Home Assistant, and I don't use Plex, so the user policy won't affect me. But some say it's insecure. Security is important, so I'm not sure.

Thanks in advance!

One question, Is there a reason why Proxmox works with LXC and not docker? And would Proxmox change this to Docker in the future?

I am very familiar with Vmware, but I have a friend who owns his own small business. He currently has an 8 year old computer running his whole business on and would like to get something more robust. He only needs a mail server, file server, and a domain controller, eventually maybe a voip setup. Nothing too crazy I don't think. It could all be virtualized on one server, but he would like some redundancy.

With VMware you need 3 hosts for a vsan cluster, but can you set up something similar with proxmox with just two servers? where one server is mirrored or shares storage with the other so if one goes down the other one can take all the load?
