    [SOLVED] Veeam v12 Native Proxmox Integration - Delivering 4.9 Gbps Backup Speeds to Offsite Storage

    Hello Proxmox Community, I wanted to share my recent experience integrating Veeam Backup & Replication v12 with Proxmox VE. We've successfully moved away from agent-based backups to Veeam's new native Proxmox support, and the results are honestly mind-blowing. Our Environment: Hypervisor...

    PMG Network Issue: ARP Incomplete on Hetzner vSwitch (VLAN Tagged) - Fresh Install Fails

    Hi everyone, I am experiencing a persistent networking issue with a fresh installation of Proxmox Mail Gateway on a Hetzner Dedicated Root Server. Despite having 29 other virtual machines running perfectly on the same host and vSwitch, this new PMG instance cannot reach its gateway. The Setup...

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    I fully understand and accept your point regarding the repository hierarchy. You are right; relying on the test-repo for a production environment of this scale was a risk that ultimately fell on me, regardless of how stable it had been over the past two years. This experience has been a clear...

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    Let’s be clear: I have been managing this 1,200+ node infrastructure for over 2 years using this exact same repository structure without a single critical regression—until now. While you point out it's a "test" repo, in a professional development cycle, a package should only reach a public test...

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    I am writing this to express my deep frustration regarding the pve-qemu-kvm 10.2.1-1 update. I manage a massive infrastructure of over 1,200 nodes, and this untested update has caused significant distress across my entire operation. I have spent the last two nights without sleep, monitoring...

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    I've been using the test for two years and this is the first time something like this has happened to me. I will be downgrading this other cluster structure after 4:00 AM.

    pve-qemu-kvm 10.2.1-1 pve-qemu-kvm 10.1.2-7 There's a difference of more than 25%. Not only IOPS but also CPU and, naturally, RAM usage has decreased.

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    Quick update: I have just downgraded pve-qemu-kvm from 10.2.1-1 to 10.1.2-7 on my nodes, and I can confirm that all IO Delay and IO Pressure issues have completely disappeared. Before the downgrade, I was seeing a constant 20-25% IO Delay even with high-performance NVMe drives. After the...

    Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository

    Glad to hear you can reproduce it. To provide more data: I have tested this across my entire rack of servers (multiple nodes), and the result is identical on every single one. They are all experiencing the same ~20-25% IO Delay since the 10.2.1-1 update. As shown in the screenshot below, all...

    I'm in the same situation, I couldn't figure out why it was like this either. I'll try dropping all the virtual currencies to 10.1 tonight.

    High IO Delay (20-25%) on AMD EPYC 7502P / Tyan S8050 with NVMe (LVM-Thin) - Despite High FIO Benchmarks

    Hi everyone, I am experiencing a persistent high IO Delay (20-25%) on my Proxmox VE 9.1.7 node, even when the system is not under extreme load. I have recently reinstalled the OS multiple times (tried ZFS, BTRFS, and currently LVM-Thin) but the issue persists. System Specs: CPU: AMD EPYC...

    Ceph - VM with high IO wait

    I'm experiencing the same thing. There's something strange going on with Proxmox 9.1.1, and for some reason, my IOPS jumps to 500%. I haven't found a solution. The actual disk is fast, but slower than Proxmox :D I think there's something wrong, a bug. By the way, I've formatted it 14 times.

    Linux backup will not work if there are files such as shell etc.? Veeam backup does not look at this and backs up directly. It's obvious that you don't do hosting.
