So, today I tested again, and now I'm not able to succeed with any fresh installations using the current build of Windows 25H2 (26200.8457). Fiona, I misspoke when I said linux VMs, as I haven't yet had a corrupted linux system, yet. The OPNSense...
Hi, ja, ist genau wie du vermutest. PBS checkt vor dem Sync, welche Snapshots bereits auf dem Ziel vorhanden sind, und überspringt sie. Der Rücklauf B→A würde daher quasi leer durchlaufen.
But RAID5/6 probably does not give good performance (in terms of IOPS, which you need for multiple VMs trying to use the drives at the same time). I though I mentioned that in my post.
Hello Udo,
Thank you very much for the explanation. I use the datastore for VMs only; static data is stored on a NAS with HDDs.
From this, I conclude that I should probably use RAID10 (i.e. 6x mirror vdevs) for performance reasons as well...
You did not say anything of the underlying filesystems...?
For ZFS it may be expected as ZFS does a lot more work than classic filesystems under the hood, resulting in multiple IO-operations used for metadata etc...

What you could also test, does the issue happen when you switch to a different Async IO setting for the virtual disk (in the Advanced settings when editing the disk in the UI)?
The deprecation itself was not strongly influenced by that, but the decision to communicate it more actively was in fact primarily driven by it. Normally, we only mentioned it on the side once a new kernel became the default. In the past, we...
It wasn't a result of any issues like this was it - https://forum.proxmox.com/threads/lxc-boot-and-vzdump-failures-on-ceph-rbd-after-upgrade-fsconfig-failed-cant-lookup-blockdev-exit-code-32.183650/

Erstmal vielen Dank für diese tolle Zusammenfassung!
Das Ablaufdatum am 15.05.2026 sehe ich auch bei meiner Kontrolle in einer VM. Warum ist denn nun dieses 2023 UEFI Zertifikat auch schon wieder abgelaufen? Das versteht doch keiner mehr.
Hello
I have confirmed that this problem emerges after upgrading a node from PVE 8 to 9. In other words, the guest was working very well in PVE8, but in 9, network breaks down. It does not happen for all the guests, but I have not been able to...
Hi @THE_BIG_ONE,
please share your /etc/pve/storage.cfg and the configuration of an affected VM qm config ID with the numerical ID of the VM. What storage type and format is used for your virtual disks, qcow2/raw/...? What was the exact error for...
Well..., it is "50%" versus "66%". For this 16% more space you lose two third of available IOPS. Six mirrors have three times the IOPS as two RaidZ2 offer, every single vdev counts.
If you are storing VMs on the resulting pool then this is...
Zu dieser Thematik habe ich auch noch etwas Senf. Dieses Thema ist wirklich verwirrend und ich trage hier mal meine Erkenntnis vor.
Was hat es mit den RegistryKeys auf sich:
Windows selbst kennt für sich nur 2 ligitime Wege, wie sich die...
No problem. I’ve read about the padding issue, and I’m not entirely sure whether it might actually make more sense to switch to a RAID10 setup with ZFS anyway.
I have a total of 12x 480GB SSDs available that I could use. At the moment, I was...
You can't migrate the linstor controller, because when the vm pauses for the final step, proxmox can't contact the storage controller for the primary/secondary changes.
So you can't install it on a vm managed by linstor itself.
Linbit provided a...
