मैंने अपने RAID 5 में एक और ड्राइव जोड़ा और इसे RAID 6 में स्थानांतरित कर दिया। 6. सबकुछ ठीक हो गया, लेकिन अब यह प्रक्रिया 63.2% पर अटक गई है और md2_raid6 CPU का 99.9 लेता है।

mdstat कहता है:

अप्रयुक्त उपकरण:
गति कम हो रही है और यह ब्लॉक 2469935104 पर अटका हुआ प्रतीत होता है। मैं सरणी को अब माउंट नहीं कर सकता, क्योंकि माउंट कमांड बस अटक जाता है।
