How to expand the volume of Fedora 35 Server?

Question

Perspectives

---

Actually I was looking for Pi OS AArch64 but it was a beta version. It's suppose to me Fedora 35 Server AArch64 would be the best alternative of Pi OS AArch64. Actually Fedora 35 Server AArch64 needed to build Quarkus AArch64 native image using Podman.

It was the first time Fedora 35 Server AArch64 downloaded and written into a Samsung 32GB EVO Plus micro SD card using Raspberry Pi Imager. It was a very easy installation but there were some strict dependencies with some external peripheral like HDMI Monitor, Micro HDMI Converter & Keyboard.

Fortunately I able to manage those peripherals. Unfortunately I unable to bypass this installation and configuration process over the ethernet using SSH like Pi OS.

So far I can remember, I never have to use any external peripherals like HDMI Monitor, Micro HDMI Converter or Keyboard to install or configure Pi OS. Only I have to rely on existing WiFi Router & CAT6 ethernet cable.

Configurations

This the first time I've to use such peripheral devices instead of CAT6 ethernet cable. I'm a bit worried as it might not be cost effective for the beginners as well for the learners. Anyway I was able to install and configure Fedora 35 Server AArch64 as following:

sudo nmcli dev wifi rescan
sudo nmcli dev wifi
sudo nmcli dev

sudo nmcli dev wifi con 'ChorkeOrg_2.4GHz' password 'sadaqah!'
sudo nmcli dev wifi con 'ChorkeOrg' password 'sadaqah!'
sudo nmcli con

sudo timedatectl set-timezone 'Asia/Kuala_Lumpur'
sudo hostnamectl set-hostname fedora
sudo timedatectl set-ntp true

disable_overscan=1 added at the end of the line of /boot/efi/config.txt to disable overscan. It will be reduced booting time. After reboot I able to access the cockpit https://fedora:9090/.

Issue: Volume Resize

But I disappointed a bit when I can't utilize the total space of Samsung 32GB EVO Plus. Please find the details as following:

lsblk
:'
NAME                   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
mmcblk0                179:0    0 29.8G  0 disk 
├─mmcblk0p1            179:1    0  600M  0 part /boot/efi
├─mmcblk0p2            179:2    0    1G  0 part /boot
└─mmcblk0p3            179:3    0  5.4G  0 part 
  └─fedora_fedora-root 253:0    0  5.4G  0 lvm  /
zram0                  252:0    0  7.6G  0 disk [SWAP]
'

Would you please guide us how to expand physical volume of /dev/mmcblk0p3 as well logical volume of /dev/fedora_fedora/root?

Answer 1

First we need to resize the partition for Physical Volume. It's can be done by so many ways but those are newbie like me can follow those steps as following:

Resize the Partition

---

sudo fdisk /dev/mmcblk0
:'
Command (m for help): p
Command (m for help): d
Partition number (1-3, default 3): 3

Command (m for help): n
Select (default p): p
Partition number (3,4, default 3): 3
First sector (3328000-62521343, default 3328000): 
Last sector, +/-sectors or +/-size{K,M,G,T,P} (3328000-62521343, default 62521343): 
Do you want to remove the signature? [Y]es/[N]o: N

Command (m for help): t
Partition number (1-3, default 3): 3
Hex code or alias (type L to list all): 8e

Command (m for help): p
Command (m for help): w
'

Then we need to expand Physical & Logical Volume as following:

Status: Before Expand

lsblk
:'
NAME                   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
mmcblk0                179:0    0 29.8G  0 disk 
├─mmcblk0p1            179:1    0  600M  0 part /boot/efi
├─mmcblk0p2            179:2    0    1G  0 part /boot
└─mmcblk0p3            179:3    0 28.2G  0 part 
  └─fedora_fedora-root 253:0    0  5.4G  0 lvm  /
zram0                  252:0    0  7.6G  0 disk [SWAP]
'

Expand: Physical Volume

---

sudo umount /dev/mmcblk0p3
sudo pvresize /dev/mmcblk0p3 
sudo pvs

Expand: Logical Volume

---

sudo lvresize -l +100%FREE /dev/fedora_fedora/root
sudo xfs_growfs /dev/fedora_fedora/root
sudo lvs

Status: After Expand

---

lsblk
:'
NAME                   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
mmcblk0                179:0    0 29.8G  0 disk 
├─mmcblk0p1            179:1    0  600M  0 part /boot/efi
├─mmcblk0p2            179:2    0    1G  0 part /boot
└─mmcblk0p3            179:3    0 28.2G  0 part 
  └─fedora_fedora-root 253:0    0 28.2G  0 lvm  /
zram0                  252:0    0  7.6G  0 disk [SWAP]
'

Finally our Physical & Logical Volume updated. Before reboot we needs to verify partitions using mount -a. If there is no more issue found then we can reboot our system.

Remount & Reboot

sudo mount -a
sudo init 6
