I. Ajout d'un nouveau disque dur/d'une nouvelle partition
Verifier que votre nouveau disque est reconnu par l'OS.
root@debianlfs:~# fdisk -lLe disque /dev/sdb n'a pas de partition, comme indique ci-dessus. Nous allons donc lui en creer un. Moi j'ai choisi fdisk pour le faire, sinon vous pouvez trouver une methode un peu plus graphique avec cfdisk ici.

Disk /dev/sdb doesn't contain a valid partition table
root@debianlfs:~#
root@debianlfs:~# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x0696187e.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes

II. Creer un systeme de fichiers sur la partition
root@debianlfs:~# mkfs -v -t ext4 /dev/sdb1
mke2fs 1.42.5 (29-Jul-2012)
fs_types for mke2fs.conf resolution: 'ext4'
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
655360 inodes, 2621184 blocks
131059 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2684354560
80 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:

III. Monter la nouvelle partition
A partir d'ici, il faut choisir son point de montage. Le mien est celui propose par le livre Linux From Scratch, qui est: /mnt/lfs avec comme format de fichier l'EXT4.
root@debianlfs:~# export LFS=/mnt/lfs
root@debianlfs:~# mkdir -pv $LFS
mkdir: created directory `/mnt/lfs'
root@debianlfs:~# mount -v -t ext4 /dev/sdb1 $LFS
/dev/sdb1 on /mnt/lfs type ext4 (rw)
root@debianlfs:~#
Verifier ensuite les droits sur la nouvelle partition.
root@debianlfs:~# mount
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=63178,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=51464k,mode=755)
/dev/disk/by-uuid/e78f726f-6437-4922-8d4c-d04539056d39 on / type ext3 (rw,relatime,errors=remount-ro,data=ordered)
tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)
tmpfs on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=283140k)
fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)
vmware-vmblock on /run/vmblock-fuse type fuse.vmware-vmblock (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other)
/dev/sdb1 on /mnt/lfs type ext4 (rw,relatime,barrier=1,data=ordered)
root@debianlfs:~#
Si les droits sur la nouvelle partitions sont trop restrictifs (nosuid, nodev et/ou noatime), cette partition doit etre remontee.
