wie würdet ihr weiter verfahren? so schnell wie es geht eine ersatzplatte rein und rebuilden? versuchen das raid mit 3 platten als read only zu mounten und sicherungen ziehen? die alte platte testen und falls es gut geht (was eher unwahrscheinlich sein dürfte) einen rebuild riskieren? server@homeserver:~$ sudo mdadm --examine /dev/sd[abcd]1 >> raid.status

u wot m8?

die alte platte testen und falls es gut geht (was eher unwahrscheinlich sein dürfte) einen rebuild riskieren? Wenn du einen rebuild machst dann imho nur gleich mit neuer Platte.

habe das raid gerade wieder online gebacht, mit 3 von 4 platten (active, degraded). morgen kommt die neue festplatte.
muss das raid zum rebuild unmounted werden?

mWn nicht, das ist ja der grund für raid, dass die verfügbarkeit erhöht wird. es wird langsamer sein aber sollte weiterhin funktionieren
