Shut down the VMWARE linux system, set the original hard disk capacity, and then start the system.

# Add a new partition and load the new partition based on the original capacity

Enter P and press enter to select the primary partition.

Enter 4 and press enter to select partition 4, because sda1, sda2, and sda3 have all been used.

Enter 8e and press enter to change to lvm.

Enter w, press enter to save the settings, and then restart the computer.

Format the new partition after it is started.
