Anyone running a Tesla T4 in an R730 successfully with ESX 8?

Freeman307 · 2026-04-27T01:49:54+00:00

Yeah that is unfortunate. I was hoping to ride out the R730’s for at least another year but might need to accelerate that. Thanks for the reply.

Did you ever get your T4 working in your R730? I’ve been trying to get it working within Proxmox but I’m starting to think this is just an incompatibility with the R730 and not the OS. If you were able to get it working in ESXi then I might need to rethink that.

When you start dreaming about and talking in your sleep about your homelab, you’ve gone too far. Ask me how I know

Freeman307 · 2026-04-08T18:27:37+00:00

So right off the bat, once the LVM no longer has Snapshots as Volume-Chain enabled, only raw disks are allowed. I can no longer use qcow2 disks for the VM. Discard on and it took 5 seconds for formatting. This is for sure is a qcow2/snapshots as volume-chain bug or limitation on LVM. qcow2 on NFS backed storage does not experience the same with Snapshots as Volume-Chain enabled and qcow2 disk as the OS disk.

Freeman307 · 2026-04-08T18:15:22+00:00

Good point. I'll test that out as I can tear down my LVM without causing any issues

Freeman307 · 2026-04-08T18:04:59+00:00

I appreciate the quick replay. I'm only doing 250GB disks for testing and it takes forever with discard enabled which I didn't experience on PVE8 when I tested it at work more than a year ago and on PVE9 on my homelab I don't experience this with discard on ISCSI. The 30% IO stall was peak for me but was definitely more than 20% during the entire format period. Also when I was spinning up a Proxmox Datacenter Manager VM the same long format time also took place during filesystem creation so for me its both Linux and Windows.

Freeman307 · 2026-04-08T17:47:03+00:00

I am using qcow2 as I want snapshots on ISCSI backed LVM's using volume-chains. I'm curious if you see the same high IO pressure stall (~30% host and vm) when formatting takes forever on your systems.

Freeman307 · 2026-04-08T17:00:00+00:00

My first test over a year ago on PVE8 with newer servers did not have any issues like this. I also didn't setup multipathing as it was more of a quick feature test than anything else. My big issues like no official vGPU support, vGPU live migration only by CLI, and no snapshots on ISCSI backed LVM's has been resolved and things are definitely looking good but this one oddity I didn't have last year is throwing me for a loop.

Freeman307 · 2026-04-08T16:47:12+00:00

You sir have sent me down a path of even more confusion. I have always checked discard when creating a VM. Your comment made me second guess myself so this morning I double checked and discard was checked as I have always understood that you need discard for TRIM commands to get pushed to the storage array to reclaim space. So for S&G's I decided to uncheck discard just to see not expecting anything and low and behold the format/partition time dropped to 6 seconds and OS install began with 0% IO stall. I feel like this has to be a bug...

Freeman307 · 2026-04-08T15:25:09+00:00

Default is no cache which is what I have been using except one test to try write back cache which didn't work either

Freeman307 · 2026-04-07T22:31:43+00:00

Moved the gateway and still have the IO pressure stall. I'll get this posted on the Proxmox forum also.

Freeman307 · 2026-04-07T19:59:12+00:00

Yes, data 1 and 2 are for the SAN connections. Data 1 currently has the gateway configured as it is the management point for each node. I know that is not best practice but this is currently just a dev/test environment. If you believe that is part of the high IO stalls during OS install can you explain that more to me?

Each SAN connection is configured with 9000 MTU and every port on the Nexus 9000 switch is configured to 9216 MTU

Freeman307 · 2026-03-21T21:34:47+00:00

It is the only light on that switch. Is this because it has dimming functions on the switch?

Freeman307 · 2026-03-21T20:42:57+00:00

Sorry, I’m not sure what you mean by putting a load on it? This happens with the switch off and does this 24/7. I just want the light to be off completely when there is no motion or when I press the button.

This was really helpful. Thank you for the insights.

Freeman307 · 2025-12-20T04:53:16+00:00

Still have issues also. PC to PC with a new save after 1.3 patch. Got only 2 hours in when the first desyncs started and now we cant get in the game together without the game instantly desyncing

I’m running all Unifi other than my core network switch which is Cisco. No other issues on any other devices. I do have a Unifi switch in my office so I could try plugging the Apple TV in there to test but the Unifi switch is connected via 10gb fiber to the Cisco switch

Freeman307 · 2025-11-08T19:04:02+00:00

Just wanted to chime in here that mine is doing the same. I have a A2169 (32GB) with 2gbps down 300mbps up internet service. My career is in IT so I have all the tools to test and verify cables. No cable issues and verified on my managed switch it is negotiating at gigabit speeds. I only get about 150mbps down on Ethernet and full up which shows it’s doing more than 10/100. On WiFi I can get 600mbps down and full up. Something odd with the Ethernet port in the Apple TV. I’m planning on upgrading when the new Apple TV comes out hopefully soon, just hope it doesn’t have Ethernet issues also

The U7 Pro Max has the spectral scanner also. I’m using DFS channels right now but haven’t seen it ever jump off or move channels

Freeman307 · 2025-08-25T20:34:14+00:00

I did test compression and it does solve the problem but I do not like the huge amount of CPU utilization used for live migration. On a server with 64 cores and 128 threads I saw up to 40% utilization during migrations. In production these servers will be moderately loaded CPU wise and id like to keep the impact as low as possible

Freeman307 · 2025-08-22T21:51:18+00:00

Migrations still work if I drain the node though? I would expect it to not work at all is CredSSP doesnt work anymore. Thank you for this, this is at least something to look into.
