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?

  • 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 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 Jan 3 '19 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 Jan 3 '19 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!

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 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!
