1. First add the disk space in the virtual machine to the size you need.
2. View current disk information
fdisk -l
Note: Use the parted -l command to solve the partition table problem in the red part.
3. Use the parted command to expand /dev/sda3
parted /dev/sda
unit s (set Size unit)
p free (view disk details)
resizepart 3 (expand the third disk)
Yes (the partition is in use, confirm whether to continue)
125829086s (the size value to which the disk needs to be expanded)
q (exit disk partition mode)
4. Use the resize2fs /dev/sda3 command to update the capacity of disk 3.
5. Use the df -h or fdisk -l command to check the disk status.
Okay, let’s call it a day.
