Reallocate available disk space from end of disk

[Terra]

Hi!
I have the following setup for a dual boot of Windows 11 and Linux Manjaro. I am now running out of space on the root filesystem (home folder is on different, slower drive). I would like to reallocate the 50GB that I’ve taken from Windows and add it to the root filesystem. What would be the most painless way to go?

Disk /dev/nvme0n1: 465,76 GiB, 500107862016 bytes, 976773168 sectors
Disk model: Samsung SSD 980 PRO 500GB               
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: A6C511AC-F4D8-479D-AE10-DF1792397FAA

Device             Start       End   Sectors   Size Type
/dev/nvme0n1p1      2048    206847    204800   100M EFI System
/dev/nvme0n1p2    206848    239615     32768    16M Microsoft reserved
/dev/nvme0n1p3    239616 776747007 776507392 370,3G Microsoft basic data
-> (50 GB of free space here)
/dev/nvme0n1p4 879147008 880195583   1048576   512M EFI System
/dev/nvme0n1p5 880195584 884389887   4194304     2G Linux swap
/dev/nvme0n1p6 884389888 976773134  92383247  44,1G Linux filesystem

Thanks for any help!

Just split off one of the bigger directories on your system, e.g. /var. Or you can create multiple partitions out of the free space and split off even more.

[Tip] Root filesystem nearly full but got a spare partition sitting around? Split off some stuff!

Difficulty: ★★★☆☆ Introduction As you should all already know by now, GNU/Linux is a FLOSS variant of the UNIX operating system design, and UNIX does not know the concept of drive letters, nor does it approach storage from the vantage of having different volumes. Instead, everything is mounted into a uniform directory hierarchy, so that regardless of what physical medium any particular group of files resides on ─ even if this physical medium is actually located in another computer across the …

Which filesystem are you using for your root partition?

Ext4

If I had to do it again I would probably go with @Aragorn 's solution but I messed up my Manjaro doing something else and did a reinstall. That was pretty fast and easy. Now I just got to get my programs back.

I would put $HOME your home directory, then you could not format it on reinstall. You will have to mount home in fstab for it to work.
