errore grub "membro RAID superfluo" su update-grub

Il mio sistema (wheezy / sid: 2.6.32-5-amd64 # 1 SMP x86_64 GNU / Linux) funziona bene - Mi chiedo solo cosa significano alcuni messaggi. Ho due mdraid array in esecuzione sul mio sistema. Ecco 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]

Uso /dev/md0come /e /dev/md1come /home. Ogni volta che update-grupè in esecuzione - o mentre grub viene in su, ricevo l'errore: error: superfluous RAID member (2 found)..

Per capire perché vorrei rimuovere questo, dai un'occhiata al risultato di update-grub:

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

Come posso eliminare questi messaggi?

Questo è un bug nello script update-grub. Dopo quanto detto nel rapporto sui bug di Debian, una patch è stata applicata a monte, quindi dovrebbe essere riparata nel pacchetto Debian a un certo momento.
