Saya tidak tahu mengapa tetapi Hetzner Root Server saya kehilangan seperempat array RAID-nya dan situasinya berbeda setiap waktu. Kali ini saya butuh bantuan lebih lanjut. Mungkin mereka ingin saya ganti ke server yang dikelola, itu sekitar 40% lebih mahal :).
EDIT: Hasil yang Diinginkan:
md3 : active raid1 sda4[2] sdb4[1]
1822442815 blocks super 1.2 [2/2] [UU]
md2 : active raid1 sda3[2] sdb3[1]
1073740664 blocks super 1.2 [2/2] [UU]
md1 : active raid1 sda2[2] sdb2[1]
524276 blocks super 1.2 [2/2] [UU]
md0 : active raid1 sda1[2] sdb1[1]
33553336 blocks super 1.2 [2/2] [UU]
Bagaimana saya bisa memperbaiki susunan serangan berikut?

Jawaban:
Partisi anggota RAID 1 di / dev / sdb adalah yang terbaru seperti yang ditunjukkan di sini ...
Jadi untuk mendapatkan hasil yang Anda inginkan, pertama-tama hentikan array md12X palsu ....
Kemudian tambahkan saja setiap partisi Anggota RAID yang dihapus kembali ke RAID1 aslinya

bagaimana saya bisa memperbaikinya? Sekali lagi terima kasih ..
