Nachteile von TrueNAS auf Proxmox vs. bare metal?

[ironfist]

Hallo ihr Lieben,

was spricht dagegen TrueNAS als virtuelle Maschine auf Proxmox laufen zu lassen und die SATA-Platten durchzureichen?

Ich wollte das so machen.

Unter dem YT-Video mit Anleitung gibt es dann einen Kommentar:

NOTE: This whole Truenas on a VM/Container thing is not the way to do it. Use Samba or NFS with Proxmox or put truenas on bare metal. This is not the right way to do things. You have been warned.

Proxmox nur als Unterlage für ein TrueNAS und sonst nix ist doch unsinnig. Das macht das ganze nur fehleranfälliger. Ich meine, es geht, ja, aber nur auf dem Blech wird es sicher nicht weniger stabil laufen.

Wenn du nur basteln und lernen willst mit deiner IT, dann ist das natürlich egal.

Zum Beispiel Abhängigkeiten.

und die SATA-Platten durchzureichen?

Platten durchreichen funktioniert nie zuverlässig: es sind dann immer noch virtuelle Platten, deren Daten eben direkt auf der Hardware-Platte landen. Wenn du so etwas bauen willst, solltest du unbedingt einen Controller per PCI-Passthrough anbinden. Nur so sieht TrueNAS wirklich die Platten und kann beispielsweise die SMART-Daten auslesen.

Nicht alles, was technisch machbar ist, auch empfehlenswert. Am Ende entscheidet das jeder für sich selber --> ausprobieren ;-)

Ich bin sicher, dass dieses Thema schon vielfach durchgekaut wurde, leider haben wir keine FAQ, auf die ich verweisen könnte...

Imho, der einzig vernünftige Weg.

Initial war pci-passthrough auf meinem Nas nicht aktiviert.
