Hi, Pete One day I did something similar to it. I had four partition: */boot/efi* */ # /dev/sda2* */home # /dev/sda3* */tmp # /dev/sda4* and my goal was to completely move my partition */home* after */tmp* and increase */* partition with the new /home's free space. I did it in a simple way: I moved the contents of / and /home to other partitions, then I joined old / and /home and I moved all contents of old / to this new partition. Let's go: I booted my laptop within a live usb and I created two new partitions (sda5, sda6), mounted them and moved all contents*:* # mounting things (you can create sda5 and sda6 either with fdisk, cfdisk or even with gparted) mount /dev/sda2 /tmp/root mount /dev/sda3 /tmp/home mount /dev/sda5 /tmp/root-tmp # partition that I created now mount /dev/sda6 /tmp/home-tmp # partition that I created now # moving contents mv /tmp/root /tmp/root-tmp mv /tmp/home /tmp/home-tmp # I highly recommend you to format both partitions that are going to be joined mkfs.ext4 /dev/sda2 mkfs.ext4 /dev/sda3 # joining / and /home # to do it, use *fdisk* to delete both (/dev/sda2 /dev/sda3) and create a new one # or use *cfdisk* to increase /dev/sda2. Suppose you're going to use fdisk (it was what I used): *umount /dev/sda2* *umount /dev/sda3* *fdisk /dev/sda* *> d # delete partition* *> 2 # partition /dev/sda2* *> d* *> 3 # partition /dev/sda3* *> n # new partition (fdisk will join free space on old /dev/sda2 and /dev/sda3)* *> 2 # probably 2 due to /dev/sda2* *> Enter 2x* *> p # print new partition scheme to verify* *> w # write change; JUST DO IT WHEN YOU'RE SURE ABOUT YOUR CHANGES.* # now, mount your new partition and move all content: mount /dev/sda2 /tmp/root mv /tmp/root-tmp /tmp/root # move home files too: mv /tmp/home-tmp /tmp/root-tmp # root-tmp is your new home partition on /dev/sda5 # finally, just update the partitions UUID on /tmp/root/*etc/fstab*: blkid | grep sda2 # looking for your new / partition UUID blkid | grep sda5 # looking for your new /home partition UUID # get both UUID and update them on your fstab file on /tmp/root/etc/fstab # I don't remember exactly, but maybe you need to update your grub: grub-mkconfig Once done, I restarted and all things were working well. If you really want to try it, *I highly recommend you to test it before* on a VM or something like that, unless you know what you are doing. I hope it can fit your problem :).
