Guten Tag,

Was könnte ich Probieren das zu reparieren.
 
Als erstes wäre wohl ein Konsistenzcheck vom Datastore sinnvoll. Der wird vermutlich fehlschlagen. Anschließend ein scrubbing vom zfs raid.
Dann wäre noch die Frage zu klaren, warum dirty bitmap fehlschlägt.
 
Es könnte auch ein Fehler im Netzwerk sein, aber ich würde wie floh geschrieben hat, erst einmal auf den Disks anfangen.
 
Ich habe eine Festplatte für den Backup Server.
Die hatte ich schon einfach nur als Directory bei meinem PBS, aber dort kam der gleiche Fehler.
Nun habe ich die Festplatte mit in ein ZFS gemacht und dort der gleiche Fehler.

Ich habe auch ein ZFS Scrub gemacht und dort kam das bei raus:

Was könnte ich noch probieren oder ist die Festplatte kaputt?
 
Wenn du kein RAID hast,bist du am Arsch. Ob die platte auch am Arsch ist siehst du gut mit smartmontools.
 
Bei den hohen Read Errors, würde ich gar nicht mehr testen, sondern tauschen. Bei Enterprise Systemen tauschen die Hersteller ab 250 Hard Read Errors aus. Du hast schon über 1,9k Errors. Also lieber weg damit.
