Hi, @DeQuzzie A measurement (a general one, not particular for Proxmox) is in the article linked by other poster. Raw performance, throughput, performance delta, dedup ratio, write and read latency - in various workloads: "Introducing OpenZFS... -

Francois Baillargeon replied to the thread [SOLVED] Boot failure on imported VM.I agree with @j.theisen here, we usually see stuff with "Inacessible boot device" upon import, hence why we ended up baking a VirtIO préinstall script for VMWare to make it smoother. It's probably just that

Yyarii replied to the thread LXC Containers Backing Up Incredibly Slow.@fabian is there any hope that Proxmox team will implement zfs block backend backup metod (zfs send|zfs receive) when using zfs storage with PBS?

Das ist ein riesiger Fragezeichen Katalog. Es wäre ratsam, zunächst einmal die einzelnen Produkte die eingesetzt werden sollen zu prüfen / anschauen / testen und deren Wechselwirkung und miteinander auszuloten. Daher wäre eine Testinstallation... -
Weil der ZFS typ besonders behandelt wird. Erstelle einen neuen Directory Speicher und gebe den Pfad zum Mountpoint eines Datasets (oder Order darin) an. Siehe zfs list. Würde ich so nicht sagen. Ist natürlich nicht selbst shared Storage.

ZFS kann mit nur einer Disk seine volle Leistungsfähigkeit nicht entfalten - Funktionen wie "Selbstheilung" brauchen Redundanz. Und man sollte gute SSDs verwenden, Faustregel: alle Typen mit "PLP" (Power-Loss-Protection). Wenn man ganz auf ZFS...

HHolemole replied to the thread KVM Windows 10 VM Help (TPM, Secure Boot, VBS, HVCI & IOMMU).Thanks for the reply and the info. The reason I want VBS and HVCI enabled is because Riot Vanguard requires them out of the box if you want to play their game. I haven’t had any issues with other games everything else works perfectly. I kind...

Gg.fiore replied to the thread Destroyed HDD with passthrough?.Good news: your disk is probably not dead. The pattern you're describing — brand new HDD that passed SMART, then disappears after a passthrough attempt and doesn't come back even after reinstalling Proxmox — is a known and recurring UGreen DXP...

Hello @Holemole thanks for posting on the forum! So first things first, i probably don't need to tell you that Windows 10 is EOL since October of 2025 and such poses a security risk if not properly isolated. Secondly VBS and HVCI use - as the...

My use case was hot storage of archive material with a modest 1.3 dedup ratio. RAIDZ3 pool of 12x10TB SAS disks with 128GB RAM, 1M recordsize/zstd dataset. Real world write speeds of about 750 MB/s on a non-dedup dataset. Dedup had a factor ~7...

j.theisen replied to the thread Cant upload iso to my proxmox host.Ok so storage wise everything seems fine. Just to be sure, how big is the ISO you are trying to upload? Can you please try to upload the ISO again and provide the output from the Task and additionally the output of the journal. journalctl... -

j.theisen replied to the thread [SOLVED] Boot failure on imported VM.Hi @hermannw thanks for posting on the forum! What is the current configuration of the VM and how was it configured on Hyper-V?

WwARNING replied to the thread Cant upload iso to my proxmox host.I am not talking about a vm inside the host, i am talking about the local storage on the host, and not trying to upload it to cluster data that is linked to my host because is almost full.

Gg.fiore replied to the thread [SOLVED] VM's won't start on boot.Good, that confirms the theory. vga: virtio in the config generates a SPICE socket under the hood even without an explicit spice line, which is why you're hitting it. Steps 1 and 2 both address this in different ways. One thing worth noting: you...
