hi ,
my / is totally full :

df -h
Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur
devtmpfs 3,9G 0 3,9G 0% /dev
tmpfs 3,9G 0 3,9G 0% /dev/shm
tmpfs 3,9G 8,7M 3,9G 1% /run
tmpfs 3,9G 0 3,9G 0% /sys/fs/cgroup
/dev/mapper/centos-root 55G 57G 14G 100% /
/dev/sda1 1014M 150M 865M 15% /boot
/dev/mapper/centos-home 42G 33M 42G 1% /home
tmpfs 782M 0 782M 0% /run/user/0

i added 100 go to hard disk

lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 200G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 99G 0 part

└─centos-home 253:2 0 21,1G 0 lvm /home
sr0 11:0 1 4,5G 0 rom

i think that my vm is not considering that i added 100 go
how can i added this 100 go to centos-root

you have to resize your vg, your lv and finally the filesystem.

there are a lot of howtos about lvm on the net. search for resize lvm...
