Edit Settings and modify hard disk size

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

[Root @ localhost ~] # Fdisk/dev/sdaWARNING: DOS-compatible mode is deprecated. it's stronugly recommended to switch off the mode (command 'C') and change display units to sectors (command 'u '). command (m for help ):

Enter n and press enter. Add a partition

Command (m for help): nCommand action e extended p primary partition (1-4)

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.

Enter df-h to check the disk capacity.
