How to increase the root partition size on Fedora

Boot up with an Fedora Live USB stick.

1. Run vgs to check if there's any space:

$ sudo vgs
  VG     #PV #LV #SN Attr   VSize    VFree
  fedora_dhcp35--100   1   3   0 wz--n- <237.28g    0 

or

Run 'lsblk'

$ sudo lsblk
nvme0n1                                       259:0    0 476.9G  0 disk  
├─nvme0n1p1                                   259:1    0     1G  0 part  /boot
└─nvme0n1p2                                   259:2    0 475.9G  0 part  
  └─luks-fce8cd76-9b7e-45d2-878b-6a8733eb32ca 253:0    0 475.9G  0 crypt 
    ├─fedora_dhcp35--100-root                 253:1    0    70G  0 lvm   /
    ├─fedora_dhcp35--100-swap                 253:2    0  15.6G  0 lvm   [SWAP]
    └─fedora_dhcp35--100-home                 253:3    0 390.3G  0 lvm   /home

2. If there is you can just run:

lvresize -L +5G --resizefs /dev/mapper/fedora_dhcp35--100-root

NB: Remember to check where your fedora root and home partition is mounted by running fdisk -l.

3. If you don't have any free VFree space, you can shrink your home partition and then extend your root partition afterwards.

To scrink your home partition run:

lvresize -L -10G --resizefs /dev/mapper/fedora_dhcp35--100-home

And then to extend your root partition run:

lvresize -L +10G --resizefs /dev/mapper/fedora_dhcp35--100-root
