Preparing To Expand Disk Space

Increasing The Virtual Machine Disk Space

Adjusting The Linux Partitions Using GParted Live

  • The 20GB of drive space we added is visible as unallocated
  • The partition we saw when checking our disk space at the beginning was /dev/sda5 and we can see that in this list with the label mysql
  • That partition is part of /dev/sda4, so we’ll need to first extend /dev/sda4 and then extend /dev/sda5
  • Note the “0 operations pending” in the bottom left of the window — we’ll be setting up actions to the partitions and will then need to apply those actions at the end.
