Efficient Data Migration and Volume Removal between EBS Volumes on EC2 Instance

Initially, I generated an EBS volume2 and created "myNewVolume." directory and mounted that point the volume2. Subsequently, I employed the rsync command to duplicate the contents of the / directory onto "myNewVolume." However, encountering difficulties, I am currently unable to switch volume2 as new root volume. Once this transition is accomplished, my intention is to eliminate the initial volume for the purpose of cost efficiency.

Have you tried the steps mentioned in the blog below? https://medium.com/@m.yunan.helmy/decrease-the-size-of-ebs-volume-in-your-ec2-instance-ea326e951bce

I adhered to the procedures outlined in the blog, but during the "preparing volume" step, I encountered the following message:

"tune2fs 1.44.1 (24-Mar-2018)

This operation necessitates a filesystem that has been recently checked.

Kindly execute e2fsck -f on the filesystem."

I do not know what I am missing.

Also, I encountered that when trying to install grub on a new volume.

"grub-install: warning: File system `ext2' doesn't support embedding."

What if you try the steps in the blog below? https://dev.to/mithlajkn/reduce-ebs-size-of-your-ec2-29p9

If you encounter an error like this "This operation requires a freshly checked filesystem."
run sudo e2fsck -f /dev/nvme1n1 to check the filesystem.

Check the system label of the old volume using the command: sudo e2label /dev/nvme0n1p1
Replace the label of the new volume with the old volume's label: sudo e2label /dev/nvme1n1 cloudimg-rootfs

e2fsck -f /dev/xvdf that command helped me.
