Hallo zusammen,

ich habe versucht 2 Setups aufzusetzen mit zfs. Bei ZFS bin ich noch ein absoluter "Neuling".

Bei beiden Systemen komme ich leider bei einem Schreibtest nur auf ca:

Sys1 (mirror) = 59.8 MB/s
Sys2 (raidz1) = 15.6 MB/s

Kommando für Schreibtest: "dd if=/dev/urandom of=file.txt bs=1048576 count=1000"

Vielleicht kann mir jemand weiterhelfen, den Fehler bei meinem Setup zu identifizieren?

schöne Grüße
felon

dd als benchmark nutzen taugt nichts, nimm fio.

Vielen Dank für die Info. Fio hat vernünftige Werte angezeigt. Leider konnten wir die NVME Auswahl beim Hoster nicht bestimmen.
Aber der Output von Fio spiegelt die Performance wieder, wenn wir eine größere VM restoren. Mich hat das ziemlich verwundert.

Das Ursprüngliche Problem, warum wir auf die write Perf kamen war, dass wir timeouts bei der Storageanbindung für Cifs haben zu unserem Storage. Da sind wir noch auf der Suche.
