Bigger than anything you will realistically need ;) As in: If you measure your storage in Terabyte (and not, I don't know Peta- or Exabyte), you will not run into issues. Make sure you understand how metadata works for thin-pools though, as that can be exhausted if not set up properly...

Please post your pveversion -v output and any logs from the time around where you shut down your VM (journalctl -e). You can also try qm status --verbose <vmid> when the VM is in the stuck state. There can be multiple reasons for this, either on PVE side or in the guest. Does this happen to any...

Wurden die entsprechenden VMs neu gestartet seit dem letzten upgrade (insbesondere von pve-qemu-kvm)? Ansonsten laufen diese einfach noch mit einer alten Version, der Hinweis im Log dazu ist mehr Warnung als Fehler. Ein reboot oder eine live-migration der betroffenen VMs sollte helfen, die...

Please open a new thread for such issues instead of replying to an old one. We're currently shipping a 5.11 kernel, making the previous response way outdated anyway, so I doubt you're experiencing the *same* issue. When opening a new thread, please provide more details, such as your network...

It's quite poetic to reply to a thread that ended with > Please don't reply to such old posts, you can always open a new topic for such questions after 4 months with another question ;) And yes, I am sure about it, this is how the ARC cache is designed to function. Unless you have modified the...

Sorry for the delay. If your still experiencing the issue, can you post your VM config ('qm config <vmid>')? Best check it multiple times, i.e. once when it's in "broken" state after reboot, once after you fix it, after running the VM, shutting it down, etc...

It might be that your audio device does not support resetting. See here: https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Passing_through_a_device_that_does_not_support_resetting In that case, it's usually not possible to fix this. You could try handling audio output on the host via...

We're investigating in this thread: https://forum.proxmox.com/threads/kernel-panic-whole-server-crashes-about-every-day.91803/ It seems that indeed something regarding to io_uring and pve-kernel 5.11 doesn't quite work as expected.

Hm, how big is the backup? Can you try to copy it to the local disk first and then restore it with qmrestore <archive> <vmid>?

Nested virt with Hyper-V on AMD is very experimental, Microsoft didn't support it at all until recently. I'd pose it up to that, without much deeper investigation this is hard to say. There are some guides out there to improve nested perf, but YMMV greatly with those. Anyway, if you want to use...

A fix for this is in git: https://git.proxmox.com/?p=proxmox-backup.git;a=commit;h=d9822cd3cb30494b2fdabd7a3670e940ad8199ae It should soon be available in repositories.

Since it seems to coincide with IO load, could you try disabling io_uring? With "cache=writeback" that is already the case, so it would seem to be a candidate. That also would be something that clearly changed in PVE 7.0. To test, edit your VM config in /etc/pve/qemu-server/<vmid>.conf and add...

And I believe exactly there lies the issue. When enabling CPU type 'host', the L1 main OS runs virtualized, because it finds the necessary CPU extensions and you have Hyper-V enabled. This of course reduces performance, since nested virt always has an extra overhead. When you then switch to...

LVM (thin) and ZFS file restore is now available in the latest PVE versions. Note that this requires an up-to-date PVE more than PBS, since the file-restore runs on the PVE node. This was an issue specifically with NTFS (you can see the fix here). If you find such issues, don't hestitate to...

This is fixed in libpve-storage-perl 7.0-9, which is available in all repositories. Make sure you have the latest updates (apt update && apt dist-upgrade) and try again. If that doesn't fix it, please post the full output of pveversion -v.

Man kann theoretisch zwei datastores erstellen, und die dann beide einbinden. Das wäre dann quasi das gleiche PBS zwei mal eingebunden, man kann ja beide datastores auf die gleiche Platte (aber unterschiedlichen Pfaden) geben. Aber zwei Anmerkungen generell: Auch beim stop-mode backup bleibt...

Best of luck setting it all up ;) And FYI, you can link your enterprise key with the forum by setting it in your 'Account Details', then you'll get a subscriber badge.

It'd be interesting to see what caused the original snapshot to hang... But for now, since the linked ZFS snapshot doesn't seem to exist (if it does, remove it with 'zfs destroy'), you can just remove the snapshot info from the config manually. Edit the VM config in your editor of choice (best...

Yes, Ryzen 5000 series is supported by kernel 5.11 and thus the newest PVE.

Can you post the output of 'df -h' as well as 'zfs list' on your PVE host? It might be the root disk getting full?
