LVM

Run the cfdisk command to format and mount the disk:

(2) Add to LVM:
A. pvcreate/dev/sdb1
B. vgextend VolGroup/dev/sdb1
C. lvextend-L + 10G/dev/VolGroup/lv_root
D. resize2fs/dev/VolGroup/lv_root
The original root directory is only 36 GB. Now, check df-h again. It can be seen that it has increased by nearly 10 Gb.
