update-grubでのgrubエラー「余分なRAIDメンバー」

私のシステム（wheezy / sid：2.6.32-5-amd64＃1 SMP x86_64 GNU / Linux）は問題なく実行されています-いくつかのメッセージの意味がわからないだけです。システムで2つのmdraidアレイが実行されています。ここにありcat /proc/mdstatます：

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]

/dev/md0as /と/dev/md1as を使用してい/homeます。たびにupdate-grup実行されている-またはGRUBが起動する一方で、私はエラーが表示されます error: superfluous RAID member (2 found).。

これを削除する理由を理解するには、次の結果を見てくださいupdate-grub。

これらのメッセージを取り除くにはどうすればよいですか？

これはupdate-grubスクリプトのバグです。Debianバグレポートでの発言の後、上流にパッチが適用されているため、いつかDebianパッケージで修正する必要があります。
