Stockage ZFS
Un « pool » de sauvegarde sur les 2 gros disques mécaniques a été créé en miroir (RAID1).
Nous avons ensuite créé un « pool » avec les numéros de série des disques (qu'on trouve dans /dev/disk/by-id), avons activé la compression LZ4 et avons créé un ensemble de partages ZFS pour stocker les disques durs virtuels des VM (le partage prod-01), et sur d'autres partages les données de hébergé⋅e⋅s, etc. qu'on montera plus tard dans chaque VM en NFS :
