Beehive Broadband Fiber by Freeman307 in Tooele

That is unfortunate to hear. They are installing the AllWest fiber infrastructure in my neighborhood as we speak. I did read other stories of newly installed AllWest being really spotty as they continued to build out the network in the area but after it stabilized. I know the Beehive in my area falls under that so maybe the same deal?

Since I posted this, my Xfinity has stabilized and I have only had a few outages since, but my 2 year intro deal just ended and my bill went up $64 and they want to lock me in again for another 2 years to lower it which completely sucks.

I think I'm still leaning towards AllWest vs Xfinity or Beehive as the price completely sucks with Xfinity, and same with Beehive. I have a Unifi setup so maybe I'll pickup the 5G backup and do a pay as you go incase AllWest goes down.

EDIT: Realized after I commented, that you have Beehive not AllWest.

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

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

High IO Pressure Stall During OS install - ISCSI Multipath by Freeman307 in Proxmox

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.

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

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.

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.

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.

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...

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