Like.
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... -
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.

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...

UdoB replied to the thread Grundsatz für 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...

Thanks @Onslow — that one actually answers the quota question from my first post: "Once the quota is reached, new writes for dedup-enabled datasets bypass deduplication and are written as unique blocks, preventing unbounded DDT growth." So it...

Thanks, both angles are useful. On the special vdev: that matches what I'd expect for the DDT lookups, but the part I can't find numbers for is the write path — does putting the DDT on NVMe actually remove the penalty, or just move it? If anyone...

UdoB replied to the thread ZFS Disk FAULTED after reboot.If you don't trust the system to be able to reboot, you cannot trust it at all! It is a pure test-system with only test-data on it, right?

UdoB replied to the thread ZFS dedup on a Proxmox host in 2026 — has fast dedup changed the recommendation?.Your statement... ...seems to come from an age more than 10 months ago. Storage is expensive now. And CPU performance on my machines is plenty - all cores are nearly idle with 4 to 14 percent usage in this very moment. That said... I am...

UdoB reacted to daanw's post in the thread Advice on upgrading home lab from Proxmox 8.4.19 to 9.x with Like.
Never had any issues upgrading while keeping the OPNsense/router VM running. Your mileage may obviously vary. Just make sure you have backups (which you should anyway) so in the unlikely case something fails you can always do a plain PVE 9...

UdoB replied to the thread Advice on upgrading home lab from Proxmox 8.4.19 to 9.x.Without guarantee: yes. But I would try to avoid that too. Yes. That's a valid use case for "Proxmox Offline Mirror" as it works... offline --> https://pom.proxmox.com/"

UdoB reacted to Johannes S's post in the thread AtlasPVE: a safety layer for Proxmox that shows what an action touches (live demo, feedback welcome) with Like.
I wonder about the target audience. Homelabbers who think PVEs community subscription is too much won't pay for this. For other setups I still fail to see what these views try to achieve. For any real large impact I will need to do the change...

Ah, come on. Docker is a container platform that relies on many of the same Linux kernel features as LXC. You don't even have to be an expert on the underlying technologies to realize that this is fundamentally different from running just any...

Wer kennt es "nicht"? Man hat einen Server und 'auf einmal' ist das Netzwerk nicht mehr verfügbar. Und wie soll man nun updates einspielen oder alles wieder ans laufen bekommen ohne Netzwerk? Was für mich immer ein guter Ansatz ist, einen USB...

UdoB replied to the thread Web Interface terminal reconnect to same session.You are already aware of tmux. What's stopping you from running tmux attach, after reading man tmux? You can also find recommendations/mechanisms to automate this cumbersome step somewhere ;-) (( My own daily driver is running tmux as my main...

UdoB reacted to TErxleben's post in the thread LXC Container kommt nicht ins Netz trotz augenscheinlich korrekter IP config with Like.
Auch auf die Gefahr hin, mich zu wiederholen. Der Gewinn von LXCs steht in keinem Verhältnis zu den Problemen, die sie schaffen. Deshalb setze ich Container grundsätzlich nur innerhalb von VMs ein. Soweit sinnvoll machbar, verzichte ich komplett...

UdoB reacted to Johannes S's post in the thread LXC Container kommt nicht ins Netz trotz augenscheinlich korrekter IP config with Like.
Korrekt, zum Hintergrund: Die meisten Distributionen (inklusive Debian) haben in ihren Container-Templates mittlerweile systemd und da dessen Sandboxing-Mechanismen den gleichen Kram wie Container brauchen, sind beide Optionen standardmäßig...
