Problem description: Previously, the disk space of Ubuntu was 20G. As more and more files are stored, the disk space has been used up to 18G, so the disk space needs to be expanded to 40G.

step:
1. Close Ubuntu, select virtual machine settings in vmware, enter the size you want to expand to - 40G, and finally click Expand.
Note: Ubuntu must be turned off, otherwise the disk space cannot be expanded.
2. Install gparted partition management software
$apt-get install gparted
3. Open the gparted software and you need to enter the virtual machine user password.
4. Delete the extend partition. The sda1 partition size can be reset only after deleting the partition.
The specific deletion method is: first right-click the swap partition, select "swap off", and then right-click to delete the swap partition. After deleting the swap partition, you can delete the extend partition.
Note: Sorry, I forgot to take a screenshot of this step.
5. Right-click on the sda1 partition, reset the size of sda1 to 38G, then right-click on the unallocated space to create an extend partition of 2G, then right-click on the unallocated space to create a swap partition of 2G, click the green check mark above to save the settings, and then select the Gparted menu Column "edit"->"apply all operations" to make the configuration take effect.
Note: The swap partition is separated from the extend partition, so the maximum swap partition can reach 2G (the maximum value of the extend partition). If you need to create another partition on the extend partition, you must reasonably allocate the disk space occupied by the extend partition to ensure that the combined size of all partitions must not be higher than the extend partition size.
6. Restart ubuntu and check whether the expansion is successful - the result is successful.
