benchmark de config raid5 sur carte raid

dimanche 19 janvier 2014, par grim_lokason

**Article à finaliser pour permettre la visualisation de tout le tableau**

script passé lors de la mise en place d’un raid5 pour choisir différent paramètres tel que :
- "read ahead" définit grâce à l’utilitaire blockdev
- "NCQ" activé ou désactivé grâce à l’utilitaire gérant la carte raid.

DISK="raid5"
SYSTEM=`uname -r`
FS="ext4"
