From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My Objective:
Repurpose an obsolete OS Filesystem as pure data storage, removing both the stuff only relevant for the OS and simplifying the directory structure so I don't have to navigate to <mount point>/home/<username>/<Data folders like Videos, Documents etc.>.

I'm tight on money and can't get an additional drive right now, so I'd prefer an in-place solution, if that is feasible. "It's not, just make do with what you have until you can upgrade" is a valid answer.


Technical context:

I've got two disks, one being a (slightly ancient) 2TB HDD with an Ubuntu installation (Ext4), the second a much newer 1TB SSD with a newer Nobara installation. I initially dual-booted them to try if I like Nobara and have the option to go back if it doesn't work out for whatever reason.

I have grown so fond of Nobara that it has become my daily driver (not to mention booting from an SSD is so much faster) and intend to ditch my Ubuntu installation to use the HDD as additional data storage instead. However, I'd prefer not to throw away all the data that's still on there.

I realise the best solution would be to get an additional (larger) drive. I have a spare slot in my case and definitely want to do that at some point, but right now, money is a bit of a constraint, so I'm curious if it's possible and feasible to do so in-place.

Particularly, I have different files are spread across different users because I created a lot of single-purpose-users for stuff like university, private files, gaming, other recreational things that I'd now like to consolidate. As mentioned in the objective, I'd prefer to have, say, one directory /Documents, one /Game Files, one /Videos etc. on the secondary drive, accessible from my primary OS.


Approaches I've thought of:

  1. Manually create the various directories directly in the filesystem root directory of the second drive, move the stuff there, eventually delete the OS files, user configs and such once I'm sure I didn't miss anything
  2. Create a separate /data directory on the second drive so I'm not directly working in the root directory in case that causes issues, create the directories in there instead, then proceed as above
  3. Create a dedicated user on the second OS to ensure it all happens in the user space and have a single home directory with only the stuff I later want to migrate
  4. Give up and wait until I can afford the new drive

Any thoughts?

Depending on the DE you use on Nobara, use GNOME Disks or KDE Partitionmanager and just open that thing and look at it.

It may have several partitions you dont need anymore, and /home is separated, containing all your users.

In that case you could just delete the others and resize the home partition to fit the contents.

If you have a / partition, you can still remove the /boot and /boot/efi and maybe swap partition. Then resize the root partition to fill all the space.

You need to mount the disk in your filemanager and use admin:/ to open it with privileged access.

Open a terminal and navigate to /run/media/USERNAME/DRIVENAME

In there do sudo chown -R USERNAME *

Then after you broke everything an OS would need but that you want, move the stuff from the homes to your root folter from the GUI filemanager. Move, not copy.

Afterwards you may want to do some ext4 repair magic, as I dont know how well ext4 likes messing around with partitions.
