Dag allen,
Ik heb een Ubuntu 18.04 server met daarin 4 3TB schijven (3 WD green en 1 blue) in raid 5. Recent failde er eentje (WD green) welke ik een dag later heb vervangen door een nieuwe 6TB schijf (/dev/sdc) (nieuwe WD Blue). Echter bij het toevoegen van de nieuwe schijf en rebuilden van de raid faalde een andere schijf (sda3, WD Green):
de array stoppen en herstarten werkt helaas niet:
Is er iemand die mij kan helpen bij wat ik nu kan doen, want ik ben bang dat ik de situatie heel makkelijk erger maak door een -f te gebruiken bijvoorbeeld Ik wil de kans dat ik een deel van mijn data kan herstellen zo veel mogelijk vergroten. ik heb liever 100% kans op 70% herstel, dan 70% kans op 100% herstel (en 30% op 0% herstel).
Alvast heel hartelijk dank! Hieronder wat aanvullende informatie:
Basis smart info. Ik heb geen self test laten draaien. Als dat nodig is hoor ik het graag.
mdadm --examine. de relevante raid is md1 (md0 ga ik opheffen en hoeft niet hersteld)
lsdrv (een script dat op raid.wiki.kernel.org gesuggereerd wordt voor informatie).

En tenslotten mdadm --examine
