De temps en temps (1 démarrage sur 60), l'un de nos serveurs debian (2.6.32-45) ne parvient pas à démarrer:
La sortie du démarrage échoué se termine ici:
...
[ 7.831991] raid6: using algorithm sse2x4 (11665 MB/s)
[ 7.839760] md: raid6 personality registered for level 6
[ 7.839838] md: raid5 personality registered for level 5
[ 7.839915] md: raid4 personality registered for level 4
[ 7.853452] md: raid10 personality registered for level 10 <<<<<<< last line of output
En comparant cela à un journal dmesg à partir d'un "bon" démarrage:
...

Je suppose que le blocage est causé par 'mdadm: envoi d'ioctl 1261 sur une partition!' mais que puis-je faire pour approfondir cette question?
