Re: Enlarging the swap partition

If I were you I would get rid off that partion schema and would change it to GUID partioning !
I don't know if it's able to do without new installation !

In my view/with my understanding: 
if you ever get in the position/the need to do an new install with new partioning your /home on an logical partition is in danger. - maybe I'm wrong ?! -

If you move to GUID partioning you circumvent the barrier of 4 primary partions OR 3 prim. plus x logical.
You simply get more then 4 primary partitions. - don't know the limit -
And you are able - during a later  new install - to leave your /home in an primary partition untouched and just mount it  during an new install. For the other partitions (/, swap, ...) you are free to format /re-partitioning them without putting /home in danger. - no need to tell that a user data backup is important anyway -

Hints:
- you need a partition named  "Bios Boot" with 1-2 MB size as a first (?) partition.
- you need (I'm unsure if this still relevant !!!) "inst.gpt" as boot parameter for your install media
https://docs.fedoraproject.org/en-US/Fedora/25/html/Installation_Guide/sect-boot-options-advanced.html

- leave some space (10-15 %) on your ssd un-partitioned ( again, don't know if this still valid)

my config:
sudo fdisk -l /dev/nvme0n1 :

Disk /dev/nvme0n1: 465,8 GiB, 500107862016 bytes, 976773168 sectors
Disk model: Samsung SSD 970 EVO Plus 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: F881C380-A695-4C12-BD2E-73B0D205EFAC

Device             Start       End   Sectors  Size Type
/dev/nvme0n1p1      2048      6143      4096    2M BIOS boot
/dev/nvme0n1p2      6144  97662975  97656832 46,6G Linux filesystem
/dev/nvme0n1p3  97662976 781258751 683595776  326G Linux filesystem
/dev/nvme0n1p4 781258752 820322303  39063552 18,6G Linux filesystem

swap is on another disk !

mount|grep ext4 :

/dev/nvme0n1p2 on /home type ext4 (rw,relatime,seclabel)
/dev/nvme0n1p3 on /home/ron/DATA type ext4 (rw,relatime,seclabel)
/dev/nvme0n1p4 on / type ext4 (rw,relatime,seclabel)

.../DATA 
- an extra partition carries movies/mp3/iso's, etc. mostly big data I'm lazy to move around during new installs.
- extra partition cause it allows to format /home too during new installs, if needed 

/home and .../DATA are backup-ed weekly !

a drawback with .../DATA if I format /home: 
/home/<user> is created during first gnome login, e.g. I can't mark it to mount it during install => a need to edit /etc/fstab AFTER first login/user creation, but I do it anyway to mount /var/tmp as tmpfs to !

cat /etc/fstab :
UUID=...  /                       ext4    defaults        1 1
UUID=...  /home             ext4    defaults        1 2
UUID=...  swap               swap    defaults,discard=pages        0 0
#
UUID=.... / /home/ron/DATA                   ext4    defaults        1 2
#
tmpfs   /var/tmp   tmpfs    defaults,nosuid,nodev,noexec,mode=1777  0 0
