====== Pour les partitions ======
===== DISQUE OS (80Go)  =====
  * Swap en début de disque (accès plus rapide) : 8Go
  * / sur le reste du disque : 72Go

===== DISQUE HOME (2To) =====
  * /home sur tout le disque : 2To

===== DISQUE VAR (8To)  =====
  * /var sur tout le disque : 8To

====== Pour le choix de l’environnement de bureau ======

xfce vs mate vs cinnamon … ? :/

Xfce offre moins de fonctionnalités mais il est plus stable et léger… pour un serveur c’est optionnel donc ça suffira :p

====== Petit soucis avec les partitions /var et /home dont les disques n’étaient pas reconnus ======

Tutoriel suivi : https://linuxconfig.org/how-to-move-var-directory-to-another-partition

Your /var directory has filled up and you are left with with no free disk space available. This is a typical scenario which can be easily fixed by mounting your /var directory on different partition. Let’s get started by attaching new storage, partitioning and creating a desired file system. The exact steps may vary and are not part of this config article. Once ready obtain partition UUID of your new var partition eg. /dev/sdc1:
<code bash>blkid | grep sdc1</code>
<code bash>
/dev/sdc1: UUID="1de46881-1f49-440e-89dd-6c32592491a7" TYPE="ext4" PARTUUID="652a2fee-01"</code>

<code bash>mkdir /mnt/newvar
mount /dev/sdc1 /mnt/newvar</code>

Confirm that it is mounted. Note, your output will be different:
<code bash>df -h /mnt/newvar</code>

Filesystem Size Used Avail Use% Mounted on /dev/sdc1 1.8T 1.6T 279G 85% /mnt/newvar

Copy current /var data to the new location:
<code bash>rsync -aqxP /var/* /mnt/newvar</code>

Unmount new partition:
<code bash>umount /mnt/newvar/  /mnt/var/</code>

Edit your /etc/fstab to include new partition and choosing a relevant file-system:
<code bash>UUID=1de46881-1f49-440e-89dd-6c32592491a7 /var        ext4    defaults        0       2</code>

Reboot your system and you are done. Confirm that everything is working correctly and optionally remove old var directory by booting to some Live Linux system etc.
