I have an issue trying to shrink a 5TB EBS volume that runs ubuntu on AWS to a 200GB EBS volume. I created the snapshot and use it to create a new volume. Create a new volume of the size I want to use. Attach the two volumes to the old instance.
Then create a file format and mount both drives on different mount points. I then use rsync to copy the data to the new sized volume from the snapshot volume and then unmount the small drive. Stop the instance and then detach all volumes and attach only the newly sized one to /dev/sda1 and when I try to reboot the instance, it keeps getting stuck on initializing for over 10mins.
Wondering if anyone knows how else I can do this as its urgent The instance is a t3a.small and presently is at 5TB and I need to shrink down to 200GB
