Due to various trials and errors and installation of Kubuntu 18.04 LTS, I have a clean install on a 120 GB SSD but I do not see the 3 TB HD where I would like to put /home.

I'm ready to reinstall if more efficient. Indeed, the HDD is only visible when installing. It is not visible with Kubuntu Partition Manager (KPM).

[edit] Now visible with Gnome Utility Disk but not in Dolphin

  • Please add the output of lsblk -a and df -a to the question. – Wayne Vosberg Dec 3 '19 at 14:31

    It won't show in Dolphin until you create, format, and mount a partition on the drive. You can use the Gnome Disk Utility for this. – Wayne Vosberg Dec 3 '19 at 15:32
  • /home will have to be an ext4 (or other Linux format) partition. I prefer not to make one very large partition. Bit more advanced is to have data partition(s) and link those partitions back into /home. You can move /home from / to new partition or if new install, just do the new install and create partition during install. – oldfred Dec 3 '19 at 15:53
  • Just mount the partition or the device to your /home directory. It won't show up as a separate device in dolphin because the device will be mounted to /home. You will see /home in dolphin and /home will represent your device just like your main root directory / represents your other storage device. /home will show up as the "mount point" when you use a command like: lsblk. askubuntu.com/questions/643441/… – mchid Dec 3 '19 at 22:09
  • Also, the Ubuntu help docs have some more information (note that you probably use ext4). – mchid Dec 3 '19 at 22:12
