How to decrease my AMI size in AWS Cloud

Question

HI,

I have one custom AMI which is 50 GB. But we don't much space. How to decrease this AMI size ? Is possible? Else How to decrease a Windows EBS volume size? In modify volume, we can only increase.

Hi@Lakshminarayanan,

You can't decrease the volume size directly. But you can do this by creating a new volume. You can follow the below steps.

1. Snapshot the volume.

2. Create a new smaller EBS volume.

3. Attach the new volume.

4. Format the new volume.

5. Mount the new volume.

6. Copy data from the old volume to the new volume.

7. Prepare the new volume.

8. Detach and unmount the old volume.

Hope this helps!

Hi,

Is possible to copy complete OS to mounted volume? Because i have installed some Applications and used Group policy and so on. So is possible to copy complete data with OS to newly mounted volume?

Hi,

Try to unmount your default partition. It may crash your instance. So don't try with your original one where you have your running application. Try with a new instance.

Hi,

I have golden AMI. Just I started instance from that AMI. Now I'm going to try copy data from C: to the newly created volume by using the below command.

>xcopy /s C:\*.* D:\

After copied data from C:\ to D:\

One message appeared like "sharing violation"
What's the issue?
