Resizing Root Partition on AlmaLinux 10 (LVM + XFS)

Since XFS filesystems cannot be shrunk, increasing the root partition requires backing up the /home partition, deleting it, expanding /root, and then recreating /home.

Prerequisites

A backup location with enough space (e.g., /mnt/w).
Root or sudo access.

Step 1: Backup Home Data

Backup all data from /home to a temporary location.

sudo mkdir -p /mnt/w/home_backup
sudo rsync -aHAX --progress /home/ /mnt/w/home_backup/

Step 2: Unmount and Remove the Home Volume

Ensure no processes are using /home, then unmount it and remove the Logical Volume (LV).

npm install @google/gemini-cli @github/copilot
cd ~/.local/bin
ln -s ~/Music/ai-tools/node_modules/.bin/gemini .
ln -s ~/Music/ai-tools/node_modules/.bin/copilot .

In the same directory, create a file called update-cli-tools.sh.
