How can I increment space for /home? My first /boot directory was 5 gigabytes and next I changed to 1 gigabyte. Now I'm confused because the change give me unallocated with size 5.02GiB. How can I add this unallocated 5.02GiB to /home?

Follow these steps to increase your /home partition.

  • Create a Ubuntu Live USB and boot from it.

  • Go to Gparted and turn off your swap partition. (Rightclick-->swap off)

    enter image description here

  • Rightclick on swap partition-- > "Resize/Move"--> Move it to the Rightmost area.

  • Right click on home partition (/dev/sda6) --> "Resize/Move" --> Increase its size by dragging it.

  • Apply changes.

Now you need to Correct the UUID entries in the fstab file.

(If you move your /boot partition)

Chroot to your original / partition and reinstall grub:

Execute the following commands in sequence.

sudo mount /dev/sda5 /mnt
sudo mount /dev/sda8 /mnt/boot
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done

sudo chroot /mnt

grub-install /dev/sda
update-grub  
exit

Update the UUID entries in fstab file as given below:

Open another terminal and execute :

sudo blkid

Open one more terminal and execute :

sudo gedit /mnt/etc/fstab

Replace the UUID entries of sda6 & sda7 (& sda8 if you move the boot partition too) with those of the output given from the blkid command.

Reboot.

  • You need to be in a live session as you can't safely operate on the disk partitions while the system is in use. The sudo blkid command is the one that gives you the UUIDs for the partitions. – Arronical Jun 15 '16 at 9:01
  • wow .Thanks man I try your solution it worked for me thanks. – Rayan_DPROGMEL Jun 15 '16 at 9:02
  • I have edited the question. You can get the UUIDs by sudo blkid . You need to do this on a LIVE usb because you are editing Swap and /boot partition. Otherwise its like Cutting off the branch one is sitting on ! . – Severus Tux Jun 15 '16 at 9:05

    @Rayan_skofw if you have a new question, please ask it separately. Remember to explain your partition setup clearly (tell us why each user only has a limited amount of disk space, are you using separate partitions for each home directory?) – terdon Jun 15 '16 at 9:35
