1. To expand the disk partition of the Linux system in vmware, the first thing to do is to expand the capacity of the disk
The above expansion is only the size of the virtual disk capacity, and does not increase the size of the Linux system partition and file system (as seen in red above).
2. Log in to the Linux system and create a new partition using the newly expanded disk

2.2 Create a new partition
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

Selected partition 4
First cylinder (5222-7832, default 5222):
Using default value 5222
Last cylinder, +cylinders or +size{K,M,G} (5222-7832, default 7832):
Using default value 7832
Note: · When selecting the new partition type above, there are two types: extended and primary partion. In this case, primary partion is selected. If extended is selected, it will be a little more troublesome. Readers can verify it by themselves.
· When selecting the size of Firstt cylinder and Last cylinder, you can choose according to the prompts. The default selection maximizes the use of the remaining space. Select the default here, that is, just press Enter.
