UdoB reacted to cwt's post in the thread Not getting good network throughput even with LACP bond with
Like.
The issue you are seeing is not related to LACP and not caused by the physical network. What you are running into is a VM topology and platform problem that becomes visible after an ESXi to Proxmox migration. The i440fx machine type is a legacy... -
Wwinnioe posted the thread Questions about OVS vs Linux Bridge and VM Isolation in Proxmox in Proxmox VE: Networking and Firewall.Hi everyone, I’m still fairly new to Proxmox and currently in the testing phase as part of a migration from VMware. While experimenting in my lab, I ran into a couple of design questions and wanted to get some feedback from people with more...

Bbrightrgb reacted to leesteken's post in the thread [SOLVED] I need help setting up double gpu passthrough with Like.
In principle software inside the VM can use the PCI(e) devices (passed through to the VM) to potentially read the all memory of the Proxmox host (via the devices still connected to the host). Whether this actually works to read the host memory...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.One last question. This only applies if the ACS patch is active, right? If you passthrough a GPU to a VM using the standard IOMMU groups (without patching), then there's no risk. Right?

FFelix_C reacted to BenediktS's post in the thread [SOLVED] Optimal number of Ceph monitor/manager/MDS with Like.
To answer that question you need to understand what your services are doing. I try to do a simple overview: Monitors have 2 tasks: 1) vote on the condition of the cluster. Is the osd in/out and up/down . Do we have the quorum to decide that...

FFelix_C reacted to fabian's post in the thread [SOLVED] Optimal number of Ceph monitor/manager/MDS with Like.
yes, 3 monitors are fine for small to medium (and 15 OSD nodes is definitely still that category for Ceph ;)) clusters. 5 is plenty, adding more is too much and much more likely to cause issues than help in any fashion. the managers are only...

UdoB reacted to ness1602's post in the thread [SOLVED] Weird RAID configurations for redundancy with Like.
Maybe in paranoid case you can go with raidz3, so that 3 disks can die? And set up spare .

UdoB reacted to VictorSTS's post in the thread [SOLVED] Weird RAID configurations for redundancy with Like.
You can do this with ZFS, albeit manually (not from webUI). You could also create 2 5-way mirror with 5 disks each, then create a RAID0 with those two vdev. Something like choosing stripping "vertically" or "horizontally". No idea on how it would...

Jjt_telrite replied to the thread TrueNAS Storage Plugin.@warlocksyno after several hours of AI research, here is our conclusion: rueNAS Python middleware is simply refusing to generate the correct PORTAL_GROUP syntax required for IP isolation. Since the middleware keeps overwriting your manual...

Bbrightrgb reacted to leesteken's post in the thread [SOLVED] I need help setting up double gpu passthrough with Like.
You always get this because devices connected to/via B550 are not properly isolated. You are not patching the kernel. You are enabling the "break the groups" that is already in the Proxmox kernel. This is unsafe because it makes it look like...

Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.Thank you, that I don't know. Thank you, that is clear to me. Even though I find it very difficult to accurately assess the risk for my specific use case. In my opinion it is very good, that in this forum the mebers tell us, that it is risky. In...

GGiggling3999 replied to the thread [Suggestion] Let VirtIO-GPU support max_outputs..For anyone wanting to achieve max_output (heads) on virtio. You need to modify your conf file, and use qemu commands instead of the proxmox built GUI/config. It would be nice to have this as a front end option You need to set VGA none, then...

Bbrightrgb reacted to leesteken's post in the thread [SOLVED] I need help setting up double gpu passthrough with Like.
ACS needs to be enabled to give you IOMMU groups. You don't need to patch the Proxmox kernel. Using the pcie_acs_override is what makes it unsafe.
-
Bbrightrgb replied to the thread [SOLVED] I need help setting up double gpu passthrough.This is to do to get IOMMU groups. And in most cases you get a big IOMMU-chipset group with B550 boards. Then you can brake this isolation an become virualized seperate IOMMU groups for the chipset group by patching the kernel with: "quiet...
