    Seems you are right. Bu very interesting. I have 2 hosts connected to one UPS. I reviewed situation with power, yes, there was switching to ups for a half a second. the whole machine is working, but only SSDs are felt it... Now i permanently disabled IOMMU in BIOS. will see more time. for few...
  2. Storage lost

    Replace its a bit harder, but i have 3 hosts. There is different power supply units and CPUs (Ryz 7 3900X,Ryz 9 3950X, Ryz 9 5900) and on all of them the same problem. Hosts are not loaded high (avg cpu usage 10%, memory not higher than 60%).
  3. Storage lost

    Trese is no any usb devices. That is a host with only power and network cables connected)))) I tried to disable iommu in bios. Still no effect. The worst thing that i cannot see what causes this.... It works fine, but in some moment it happens. And nothing in logs
  4. Storage lost

    Actually, i do not need IOMMU at all. I'm not using devices passthrough to VMs. i tried to passthough GPU but there is nothing good with this motherboard. so i removed "amd_iommu=on" from grub. also there is nothing connected to usb ports.

  6. High I/O delay and non-responsive VMs while migrating vm disk to zvol

    I can tell you more))) I'm using Linux not so long (~10years) but i didn't ever seen that some of disks (new hardware) suddenly was lost. I posted in in my separate thread. If interesting
  7. High I/O delay and non-responsive VMs while migrating vm disk to zvol

    My hardware config is very simple. 1NVMe with proxmox installed and 3 SSD in SATA ports. With replication enabled i didn't try. But very interesting thing that neither nmap nor in logs i couldn't see what causes this.
  8. High I/O delay and non-responsive VMs while migrating vm disk to zvol

    Maybe offtopic, but recently i faced the same problem. But all storages are LVM-Thin. For many tries, reviewing logs (there is nothing interesting) i found that if in VM disk "discard" option is enabled - the problem exists. Simply disabling discard in VM which needs to be migrated - all works...

  10. Storage lost

    No. there is very simple host config. NVMe is on M.2, on rest 4 SATA is 1 HDD and 3 SSD. All SSD is new. (on one host Goodram CL100, Crucial MX500; on other 2xAMD Ryzen5 and Sams QVO 870) I found interesting post here, but disablin...
  11. Storage lost

    Hello. Time by time i have a problem that my SSDs have an errors an storage is unaccessible. A few lines from log: And then with all othed SSDs. But NVMe (on which proxmox is installed works fine). After host restart all works fine. Same problem i have on few nodes (on other proxmox...
  12. Cores CPUs Threads

    I mean that E5-2630v4 have 25Mb cache but reported only 16Mb. Also: "args: -cpu " replaces all cpu flags. So consider to use "host" then view "qm config VMID --verbose" and use all cpu flags from there and only then add -hypervisor, +ht (or +svm for AMD) But on AMD processors -smp threads...

    Hi. I was seeking for this question for a long time. You can manually set cpu topology, but it consumes resources heavily. as an example for 1x Intel Xeon D-1520 use args: -cpu...

    I have the same problem. Nothing from above posts are not helps. I found that that issue make palce only when i try to move ".raw" image to lvm. ".raw" disk image was made by restoring backup.
