Been toying around trying to get GPU passthrough in Proxmox on my Dell Inspiron 5567 with AMD R7 M445... (not sure if it is even possible)

Tried everything and at the end I tried to extract the vbios and input it in the rom section of the PCI passthrough. Extracted it, started the VM. What do you think happened?

I crashed my host :)

I am 400km away from it. It has BIOS power on on AC. Just can't get my heart straight to ask a neighbour to pull the plug on my home :))))

What I learned here. Just get a cheap ass Wifi smart plug to be able to reset the server. (also will be able to monitor the power draw).

Or if you are more hardcore a PiKVM or something similar.

Wish you all happy holidays and a happy new year!

P.S. My UPS is the laptop's almost dead battery :P. Hate me all you want.

So I have a GL360 G8 and it quite frankly is a huge pain in the ass to get it to boot to the internal HDD without the hardware RAID controller.

I was thinking because it's VERY easy to boot USB/SD card could I run GRUB but point it to the internal drive I want to have the OS on it? (This case ProxMox running in RAID 1) That way im not using the read/writes on the USB/SD card?

How would I go about doing this?

I've been running idrac fan docker for a while in LAN mode, it logs idrac user and password which I don't quite like.

Recently after a closer look I saw it actually can run in Local mode by passing /dev/ipmi0 with below

https://github.com/tigerblue77/Dell_iDRAC_fan_controller_Docker

services:
  Dell_iDRAC_fan_controller:
    ...
    environment:
      - IDRAC_HOST=local
    ...
    devices:
      - /dev/ipmi0:/dev/ipmi0:rw

I use proxmox, so first come to mind is privileged LXC to be able to run docker and device pass through. But "privileged LXC" always comes across to me like "be warned"

Then there's the possibility of making the LXC unprivileged. I'm not sure if possible since I've been using VM exclusive prior

Last is trying to pass /dev/ipmi0 to VM. Not sure if its same as PCI pass through, most likely not

I'm curious what's the popular ways every one else runs it.

Hello fine people,

I'm currently running TrueNAS Scale on a Dell Precision T5820 with an Intel Xeon W-2135 processor. I currently have four 8GB modules for a total of 32GB (the S32R config in the attached table). The modules are Micron 1x 8GB DDR4-2400 RDIMM PC4-19200T-R.There are another 4 memory slots available and would like to add addition modules. The owner's manual is pretty good, but there is still a few things I'm not clear about.

My original plan was just to add an additional four identical modules and double the memory (i.e., 8x 8GB). But, it occurred to me that I could instead install the 16GB or 32GB equivalents that Micron produces. Unfortunately, 16-8-16-8-8-16-8-16 or 32-8-32-8-8-32-8-32 configurations options are not mentioned in the memory owner's manual memory configuration table. So, what I'm wondering is:

1. Instead of an additional four 8GB modules, is there any reason I couldn't instead add 16GB or 32GB modules?
2. Do I have to add four modules or could I simply add two (e.g., 4x 8GB + 2x 16GB)?
3. Of course the memory channels need to be paired, but do the larger modules need to be in the lower DIMMs (e.g., DIMM1 and DIMM2)? I ask, because if I'm able to add in larger sticks, I would need to consider whether I need to move the existing 8GB modules to different channels or if I can just leave them where they are).

I'd be most appreciative if anyone would be willing to share their knowledge or thoughts on these.

Kind thanks!

I'm building a 10" rack with a 5 disk jbod and want to use a mini PC to run unraid. I'd prefer to avoid using an itx motherboard open in the rack so considering a mini PC.

As its running on unraid usb i wont need the m.2 nvme slot so wondering if anyone has used an m.2 to SATA adapter on any of these with success?

If not then im thinking potentially the lenovo M720q with the pcie riser and sticking either a hba or a sata adapter on there instead.

Thought i would ask before i bite the bullet.

Not concerned about physical space in the mini pc in terms of clearance as i can remove the top

Recently I switched from using Longhorn to OpenEBS's Mayastor engine for my k3s cluster I have at home.

Pretty incredible how much faster Mayastor is compared to Longhorn.

I added more info on my blog: https://cwiggs.com/post/2024-12-26-openebs-vs-longhorn/

I'd love to hear what others think.

Just starting the process of creating my first homelab, all virtualized on a proxmox server. I'd like to be able to connect to and manage VMs within the various VLANs behind the pfSense firewall from computers in my home LAN (e.g., 192.168.1.73). I know there's various ways to do this, and will eventually be setting up a VPN, but I'm fairly certain this could be a use case where static routes entered into my Verizon Router (192.168.1.1) pointed at the WAN interface of pfSense should work. However, I'm unable to ping any of the VMs behind the pfSense firewall from computers in my home LAN. Appreciate any pointers, as I'm just about convinced the static route feature in my Verizon Router is broken (see picture for route configuration). A couple points:

• All VMs within the various VLANs have internet connectivity, and all VMs can ping computers in my home LAN. All VMs behind the pfSense firewall can ping each other.

• A traceroute ran from 192.168.1.73 to 10.10.99.3 just shows traffic hitting the Verizon Router, and then nothing afterwards, which is why I'm convinced this is an issue with static routing on the Verizon Router.

• I've configured the pfSense WAN interface (192.168.1.150) to allow for management, and I unchecked the "block private networks" option.

• My server running proxmox (192.168.1.212, single NIC) is hardwired into my router. I have a virtual bridge (vmbr0) serving as the WAN interface to the pfSense VM, and a VLAN aware virtual bridge (vmbr1) serving as the LAN interface. The 10.10.x.254 IPs are the static IPs of the VLAN interfaces configured in pfSense.

Thanks!

I was thinking about marking the sections on my switch, e.g. uplink ports and VLANs as a help to know where to plug in what (e.g. ports for hypervisors need to pass trough all VLANs, ports dedicated to APs only some, then others only a single VLAN etc). If somebody has done it, i'd be curious about some inspiration.

I keep seeing pictures of other people's efforts. Here's mine.

Lives in my garage. 12v fans active at the top, Front inlet fans at the bottom.

2 synology, for storage and a redundant backup

1 mini pc for powerdns/pihole 8 port kvm and keyboard/screen

1 dell r230 for docker, 64gb/ 8 cores - ubuntu /docker

3 hp dl360 gen9 do the heavy lifting, 256gb per, 48 cores each. Proxmox (also kubernetes)

1 4u whitebox with a 3080, for various AI tasks (openwebui and invokeAI primarily)

Ambient remains around 22-23c on average. maybe 30db max? (I haven't measured it recently).

Not shown is a larger APC ups and secondary battery (too big to fit in the rack, probably 10u total and 700lb)

When I started on this journey (almost 20 years ago now), i had just a mini pc, a linksys router, and a cheap no-name battery backup. At the time, it did everything I needed, it used little power, and was quiet enough to fit in the limited space I had available and not disturb me.

This rack has been replaced twice in the last decade, with every component shown (other than the kvm/screen) replaced at least once.

I hope you enjoy the picture. Network cabling is thanks to my wife, who makes a tidier patch panel than i ever could. I do you the decency of not showing you the back of the rack .. which .. well.. eek.

Couple days ago, I posted about my experience setting up a NAS and how it’s changed the way I manage my data. I’ve got some really great feedback that’s made me think about things I hadn’t considered before. One comment really stood out: “Don’t put all your eggs in one NASket.”While I thought I was covered with RAID 5 for automatic backups, I never considered the risks like fire, hardware failure, or the need for off-site backups. Someone even shared a story about how their in-laws' house burned down last year, and it really hit home for me. That experience was a wake-up call for them, realizing they weren’t doing enough for off-site backups, even though they had everything stored across multiple drives.So I’m looking for proper backup recommendations. How do you handle off-site backups? How do you protect against hardware failure or other disasters? I’d love to hear what strategies or tools you’re using to back up your data safely!

Hello all,

I am very confused and could use some help.

R720, get the error: 'secure connection failed' when I try to connect to IP in browser, I am able to ssh into IP, and ping the IP so I know it works.

I have tried a ton of things on google, 'racadm get idrac.webserver' gives me this error:

ERROR: SWC0244 : Invalid Fully Qualified Device Descriptor (FQDD).

I have also tried:

Soft resetting from ssh, hard resetting from ssh, unplugging server for 5 minutes, port forwarding port 443.

I have an enterprise license, but I can't enable it because I can't get into iDRAC online.

Any help would be so appreciated, I'm stuck.

My work just sent me a desktop to use since I work remotely. Issue is, I already have my own desktop with 3 monitor setup. I need to find a good KVM that can switch between these two desktops while using the same keyboard/mouse and 3 monitors.

Ive never used a KVM before - are they fast? Or do I need to wait 20 seconds or so for it to switch properly? Not looking forward to having to set this all up, but I have no choice since Im also limited in apartment space.

Thanks for the info!

Hello my fellows, I have plans to replace my raspberry pi 4 with more powerful setup. Currently I use the raspberry as a personal cloud with NextCloud, some databases instances , penpot and a git server using forgejo. My goal is have more robust system with Raid configuration and more powerful than my raspberry (nextcloud is a little bit slow on it), also probably I'll install proxmox inside to manage all containers and VM My options are: 1: Buy a n100 mini PC from aliexpress with 2 slow of 3.5 hard drives slots 2: I have an unused ryzen 3300g so probably I have to buy all remaining components including power supply, motherboard, etc.

So today I woke up to my server completely dead. IPMI still worked but simply said that the host was down. No error logs, nothing! Went to the server and found its fans spinning normally, power button LED lit and NICs also apparently up. Everything was down though; TrueNAS Scale, all VMs… yay.

After troubleshooting (checking / reseating all other components), the conclusion is that the motherboard that is only one year and a few month old, has crapped out. I can’t even access the BIOS. The POST code stays at 00 and the power management options in the IPMI interface + the power button do nothing…

At this time, I started Googling... I use an AsRock Rack B650D4U motherboard and apparently there’s a bad batch of these that die exactly with these symptoms. Great! Luckily it’s still under warrantly, so I hope there will be a quick swap to a newer hardware revision that doesn’t suffer this issue.

Anyway, happy Christmas everybody!

I recently purchased a Rackmate T1 10-inch rack and am at a loss for what to install in it. I’ve already added an ASUS router and a TP-Link unmanaged switch. I’m enrolled in a high school computer networking class, and I thought it would be a good opportunity to experiment with the rac, play around with it, but also reinforce the concepts we’ve learned in class. Any suggestions or guidance would be greatly appreciated. Thank you.

Hi everyone.

I set up a pretty simple home server/homelab using an HF SFF PC and connected it to the home router via LAN, which stands on a pretty big wardrobe in one of our rooms. My parents would like me to move the server somewhere else, prefferably my room. We don't have any LAN connections in our house, so I would have to connect the server wirelessy. Are there any options that would work well for my situation? Could connecting my homelab devices to a switch, and then to an access point be an option? Apologies for any mistakes I have made, as I am new to networking.

Thought I'd share the experience with my HPE Apollo 4200 Gen9 running TrueNAS Core 13.0-U6.1.

Specs:

• 12x 18TB Toshiba MG09ACA1 HDD
• 5x 10TB HGST HUH721010ALE601 HDD
• 6x 10TB WD101EDBZ-11 HDD
• 1x 10TB WD100EMAZ-00 HDD
• 6x 4TB Micron 5100 SSD
• 1x 1TB Crucial CT1000P3SSD8 SSD (boot drive)
• 1x Mellanox ConnectX-5 EN 25GbE Dual-port SFP28 Adapter
• 1x HP Ethernet 10Gb 2-port 560FLR-SFP+ Adapter
• 1x Smart Array P840ar Controller (HBA-mode)
• 1x Smart HBA H240
• 2x Intel Xeon E5-2620 v4
• 8x 32GB HPE Standard Memory
• 2x 1400 watts power supplies

The HDD's are running in 2 RAIDz3's striped together (12x 18TB, 12x 10TB) providing SMB.

The SSD's function as a NFS share for my VMware cluster.

Besides the occasional ciss hiccup from the P840 (one drive disappears and comes back after a cold boot) and the power usage close to 400 watts, the system has been rock solid for the last six months being my main storage server. It's being used very extensively.

Hello, I'm fairly new to homelabs and bought this NIC from Ali Express. I have an x16 slot in my Cisco C220M4 Proxmox server but this one turned out to x8, a silly mistake for not checking. However, I found out that it should still work, so I plugged it in, connected it to the router. I see lights blinking however, I do not see my router showing it in the connected devices. I tried it in my Windows PC, again X16, same thing happened, LEDs blinking but not getting detected, the device manager didnt show anything. How can I make it work? Thanks for your time and help.
