chemin du volume logique que vous voulez agrandir: /dev/vg00/lv01
Augmenter la taille du volume logique avec le programme lvresize:
root@localhost:~# lvresize -l +100%FREE /dev/vg00/lv01
Size of logical volume vg00/lv01 changed from 47,61 GiB (12189 extents) to 117,61 GiB (30109 extents).
Logical volume vg00/lv01 successfully resized.
Redimensionner le système de fichiers à la nouvelle taille à l'aide de resize2fs:
root@localhost:~# resize2fs /dev/vg00/lv01
resize2fs 1.44.1 (24-Mar-2018)
Filesystem at /dev/vg00/lv01 is mounted on /; on-line resizing required
old_desc_blocks = 6, new_desc_blocks = 15
The filesystem on /dev/vg00/lv01 is now 30831616 (4k) blocks long.
