grub error "anggota RAID berlebihan" pada update-grub

Sistem saya (wheezy / sid: 2.6.32-5-amd64 # 1 SMP x86_64 GNU / Linux) berjalan dengan baik - Saya hanya ingin tahu apa arti beberapa pesan. Saya memiliki dua array mdraid yang berjalan di sistem saya. Inilah cat /proc/mdstat:

Personalities : [raid1] [raid6] [raid5] [raid4] 
md1 : active (auto-read-only) raid5 sda3[0] sdc3[3] sdb3[1]
      823103488 blocks super 1.2 level 5, 512k chunk, algorithm 2 [3/3] [UUU]

md0 : active raid1 sda2[0] sdc2[2](S) sdb2[1]
      72628769 blocks super 1.2 [2/2] [UU]

Saya menggunakan /dev/md0sebagai /dan /dev/md1sebagai /home. Setiap kali update-grupberjalan - atau sementara grub muncul, saya menerima kesalahan: error: superfluous RAID member (2 found)..

Untuk memahami mengapa saya ingin menghapus ini, lihat hasil dari update-grub:

error: superfluous RAID member (2 found).
error: superfluous RAID member (2 found).

Bagaimana saya bisa menyingkirkan pesan-pesan ini?

Ini adalah bug pada skrip pembaruan-grub. Setelah apa yang dikatakan dalam laporan bug Debian, tambalan telah diterapkan di hulu sehingga harus diperbaiki dalam paket Debian pada suatu waktu.
