1. Add a new hard disk to the client in VM WARE ESXi

2, restart the client

3. View entire disk space with Fdisk–l

4. Add a new hard disk to the physical volume with Pvcreate/dev/sdb

Pvcreate/dev/sdb

" /dev/sdb " successfully created

5. Add a new hard disk to the volume group with Vgextend Volgroup/dev/sdb

Vgextend Volgroup/dev/sdb

" VolGroup " successfully extended

6, diffusion space lvextend-l +200g/dev/mapper/volgroup-lv_root for root partition

7, apply it to Resize2fs/dev/volgroup/lv_root
