Big time linux noob here.

A colleague helped me with partitioning my PC and I'm looking for help in resizing my /home partition. I am running opensuse leap 15.1. A few looks at my setup:

Via fdisk -l:
Code:
Disk /dev/nvme0n1: 238.5 GiB, 256060514304 bytes, 500118192 sectors
Disk model: SAMSUNG MZVLW256HEHP-000H1

/dev/nvme0n1p6 493983744 498178047   4194304     2G Linux swap

Partition table entries are not in disk order.

/dev/sda3  825608192 1953525134 1127916943 537.9G Linux filesystem
and via lsblk:
Code:

└─nvme0n1p6 259:6    0     2G  0 part [SWAP]
I basically want to allocate some some of the sda3 partition to /home. 100 gb, let's say. I tried to follow https://www.howtogeek.com/442101/how...er-hard-drive/ but I think attempting changes while on the mounted system wouldn't let me unmount my partitions. This is the same issue I have had in trying to use the KDE Partition Manager.

Please let me know if I can restructure my question or provide any other command-line outputs to make my situation more clear.

Thanks.
