To shrink the /home partition without losing data and reassign the unused space to the / partition, you can follow these steps:

1. Boot into a Live CD environment, like GParted Live or a CentOS Live CD.

2. Open a terminal and install lvm2 if you don't have it. On CentOS, you can use:

sudo yum install lvm2

3. Scan for available logical volumes:

sudo lvscan

4. Mount the root filesystem for modification, assuming your root volume is named vg_root-lv_root:

sudo mkdir /mnt/root
sudo mount /dev/mapper/vg_root-lv_root /mnt/root

5. Take note of the current /home logical volume, and unmount any existing mount points. Assuming your volume is vg_root-lv_home:

sudo umount /dev/mapper/vg_root-lv_home

6. Shrink the /home logical volume using lvreduce. Substitute SIZE_TO_BE_REDUCED with the desired shrink value (e.g., 10G):

sudo lvreduce --resizefs --size -SIZE_TO_BE_REDUCED /dev/mapper/vg_root-lv_home

7. Check the available space using:

sudo vgdisplay

8. Extend the / logical volume (assuming it's vg_root-lv_root) with the available free space:

sudo lvextend --resizefs --extents +100%FREE /dev/mapper/vg_root-lv_root

9. Unmount and reboot:

sudo umount /mnt/root
sync && sudo reboot

This should shrink the /home partition and extend the / partition without data loss or affecting the normal functioning of the system. However, always ensure that you have a backup before performing any partition tasks, just in case something goes wrong.
