Thanks for the tracker link @robertlukan . It also affects testing - cloning from the secondary is a common way to practice a recovery without touching replication. For the 50TB question, @alexskysilk'` math is the way to figure it. Two things to add: Live restore : It starts the VM before...

Thanks, this is great detail. The command transcript especially. With krbd the snapshot mode should be fine since it doesn't need the journaling feature on the image. Journal mode is a different story though. There was a full patch series for kernel rbd journaling back around the 5.3 Kernel...

Hi @Rajan_Kumar.Jaiswal@sita. , welcome to the forum. Following @Francois Baillargeon suggestion, you may find some useful information here: https://kb.blockbridge.com/technote/proxmox-tuning-low-latency-storage/ Blockbridge : Ultra low latency all-NVME shared storage for Proxmox -...

Thanks, @christophe! That's more configuration coverage than most reports we've found. "The multi-cluster equivalent of intra-cluster pvesr" is a good way to put it. Since you've run both modes in both directions, a few things you're in a rare position to answer: 1. What did "some care...

Hi Everyone, Disaster recovery keeps coming up with folks moving off VMware, usually as some version of "what replaces SRM?" We've answered pieces of this in threads for years, so we finally sat down and wrote the whole thing up properly. Mapping VMware DR Features to Proxmox VE: SRM, vSphere...

Hi @xybo, yes that applies to ZFS as well! Cheers Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox

Hi @Sisdyiyy , welcome to the forum. We have covered the performance comparison between the windows controllers in our KB here: https://kb.blockbridge.com/technote/proxmox-optimizing-windows-server/part-4.html Hope it helps in your decision making. Cheers Blockbridge : Ultra low latency...

Hi @powersupport , This topic has been discussed recently over here: https://forum.proxmox.com/threads/upgrade-from-proxmox-ve-8-4-x-to-9-1-veeam-related.185270/#post-862853 The answers to your questions are: 1, No 2. Not sure if older packages are available - you can query the repo for a...

Hi @grass127, We do have a lot of this data internally, but it isn't organized as methodically as the original tech note was, so it's hard to publish anything rigorous. What I can tell you is that the relative changes in performance are not massive. The hardware updates are delivering as much...

Hi @hishamrixs, welcome to the forum. While I understand, and often share, the sentiment expressed by other posters that different backup products might be better suited to your particular use case, we also have to recognize the business and operational requirements that are often outside a...

A few notes based on our experience with NVMe/TCP and PVE: Your performance expectation should come from your storage stack, not your choice of protocol. The transport is usually not the bottleneck in setups like this. If you're seeing latencies above a few hundred microseconds with iSCSI (high...

Hi @Howard A2 Labs , Perhaps if you provide your VM and Storage configuration and state, that may help others to zoom in on the issue. qm config [vmid] pvesm status pvesm list [storage] cat /etc/pve/storage.cfg Depending on the storage type, equivalent of : lsblk lvs pvs vgs etc Blockbridge...

Given your report that you have not found any IO related messages in "dmesg" and "journalctl" that is a pretty strong indication that the error is coming from a higher application layer. Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox

Hi @sudomaster.ljs , There have been multiple reports in the last few years of users experiencing similar issues with the combination of Veeam and PVE. Unfortunately I do not recall any of the reporters coming back with a concrete resolution. Note that Veeam has a unique way of integrating with...

Then your only option is to find a Kernel that works with the card. You may want to look into Ubuntu HWE Kernel. Blockbridge : Ultra low latency all-NVME shared storage for Proxmox - https://www.blockbridge.com/proxmox
