আমি আমার হোম সার্ভার বন্ধ ছিল আজ বাড়িতে পৌঁছেছেন (কেন ধারণা না)। আবার এটি চালু এবং RAID অ্যারে মাউন্ট করতে ব্যর্থ হয়েছে।
/ proc / mdstat দেখায়:
Personalities :
md0 : inactive sdh[7](S) sdc[2](S) sdd[1](S) sdb[3](S) sde[0](S) sdg[5](S) sdi[6](S) sdf[4](S)
39069143232 blocks super 1.2
unused devices: <none>
এবং mdadm --detail / dev / md0 বলছে RAID গুলিটি raid0 হয়, যখন এটি আসলে raid6 বলে অনুমিত হয়।
প্রতিটি পৃথক ড্রাইভে mdadm -E এ খুঁজছেন। Sdg থেকে পৃথক সমস্ত ড্রাইভ AAAAA.AA এর একটি অ্যারের অবস্থা রয়েছে, এটি একটি ইভেন্ট গণনা 191578 এবং রাষ্ট্র সক্রিয়।
তবে sdg, এএএএএএএএএএএএএএর একটি অ্যারে স্টেট এবং 69২86 এর ইভেন্ট গণনা রয়েছে এবং রাষ্ট্রটি পরিষ্কার।
এছাড়াও উল্লেখ্য, -E এ প্রদর্শিত অ্যারের UUID অ্যাটাক UUID এর মধ্যে /etc/mdadm.conf- এর মধ্যে আলাদা - যদিও এটি অতীতের একটি সমস্যাের কারণে হতে পারে যেখানে মেশিনটি হ্রাসের শুরুতে ক্র্যাশ হয়েছে , এবং আমি চালানো ছিল mdadm -CR /dev/md0 --metadata=1.2 --raid-devices=5 --level=6 -c512 /dev/sdb /dev/sdc /dev/sdd /dev/sdf /dev/sde --assume-clean
যা সমস্যা সমাধান, কিন্তু আমি অনুমান করছি এটি অ্যারে UUID পরিবর্তন।
রেফারেন্সের জন্য, সিস্টেমে একটি বুট ssd (/ dev / sda) মাদারবোর্ডের সাথে সংযুক্ত থাকে এবং RAID 5 অ্যারের জন্য 8 টি 5 টি বি ড্রাইভ (/ dev / sdb / dev / sdi) দ্বারা একটি ডেল পার্স এইচ 310 আইটি মোডে সংযুক্ত থাকে।
সব ড্রাইভের জন্য আমার mdadm -E এর আউটপুট:
