Convert Instance Store machine to EBS

Convert a server running from Instance Store to EBS

• Create 1 EBS volume (in the same availability zone that your instance is running)
• Attach this volume to your EC2 instance store (from the console)
• Format it as ext3

mkfs.ext3 /dev/sdf

• Mount it

mkdir /mnt/ebs
mount /dev/sdf /mnt/ebs

• Copy the root file system to the EBS (make sure to stop all relevant services like MySQL to ensure files are closed and flushed)

rsync -avHx / /mnt/ebs
rsync -avHx /dev /mnt/ebs

• Sync and unmount

sync && umount /mnt/ebs

• Create a snapshot of that volume
• Register the ami based on that snapshot
