This question already has an answer here:

I'm new to Ubuntu. I've allocated 110 GB to my root partition and I have 315 GB unallocated space and I'm trying to extend my root partition to include the excess 315 GB. I have searched for other methods but i can't understand the process because I have missing partitions like linux-swap and the extend partition.

My disk management picture in GParted

And also i tried unlocking my ext4 partition but it said

currently in use disk is busy

How can I extend my root partition to use the unallocated space to its left?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Please edit your question to include the terminal output of free -h, sudo blkid, and cat /etc/fstab. Please also explain how your disk partitions got to look like this. Had you been deleting partitions? Does Ubuntu run properly? Report back to @heynnema – heynnema Dec 1 '18 at 15:47
  • @heynnema i did all the commands that you said and this the output. $ free -h total used free shared buff/cache available Mem: 9.7G 1.9G 6.0G 344M 1.8G 7.2G Swap: 2.0G 0B 2.0G – Carl Dennis Alingalan Jan 3 at 1:20
  • Umm, i deleted some partitions. but it was windows 10 partitions, initially i install ubuntu dual boot with windows 10. then afterwards i deleted win10 and i just followed the instrustions in youtube and not knowing that the swap partition is need for this kind of issue. any tips for me to do to properly or should i just reformat it with ubuntu again? if so can you suggest a proper partitioning of disk? @heynnema – Carl Dennis Alingalan Jan 3 at 1:26
  • Just go ahead and follow my answer, below. It looks like you've created a 2G swapfile, so you don't need a swap partition. Please remember to accept my answer if it was helpful. Thanks! – heynnema Jan 3 at 2:06

Make sure that you have a good backup of your important Ubuntu files, as this procedure can corrupt or loose data.

Keep these things in mind:

  • always start the entire procedure with issuing a swapoff on any mounted swap partitions, and end the entire procedure with issuing a swapon on that same swap partition

  • a move is done by pointing the mouse pointer at the center of a partition and dragging it left/right with the hand cursor

  • a resize is done by dragging the left/right side of a partition to the left/right with the directional arrow cursor

  • if any partition can't be moved/resized graphically, you may have to manually enter the specific required numeric data (don't do this unless I instruct you to)

  • you begin any move/resize by right-clicking on the partition in the lower part of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window

Do the following...

Note: if the procedure doesn't work exactly as I outline, STOP immediately and DO NOT continue.

  • boot to a Ubuntu Live DVD/USB
  • start gparted
  • right-click on /dev/sda9 and select move
  • move the entire /dev/sda9 partition all the way to the left
  • resize the right side of /dev/sda9 all the way to the right
  • click the Apply checkmark

Reboot the computer.

  • +1 but OP seems not to have a swap partition, possibly because they have a swap file instead? They seem confused about that, so maybe you could add some hints about it – Zanna Dec 1 '18 at 15:17

    @Zanna you may be right. OP is confused, and has probably deleted a few partitions... as they only show sda7/8/9. I've left a new comment for OP, but they haven't responded to anybody since 11/26/18. I'll amend my answer if they do. Thanks! – heynnema Dec 1 '18 at 15:50
