/tmp 256MB
/var 1024MB
/usr 4096MB
/opt rest od disks ( aka /home )
#
# two root raid
#
/ /dev/hda1 + /dev/hdd1 /dev/md0 raid1
/tmp /dev/hda2 + /dev/hdd2 /dev/md1 raid1
/var /dev/hda3 + /dev/hdd3 /dev/md2 raid1
/usr /dev/hda5 + /dev/hdd5 /dev/md3 raid1
/swap /dev/hda6 + /dev/hdd6 /dev/md4 raid1
/2 /dev/hdb1 + /dev/hdc1 /dev/md5 raid1
