Convert from instance store to EBS

One client that was running a older EC2 instance was using instance store.

From my point of view the only benefit for instance store is that it has

better IO..though if you build a RAID using several EBS volumes.

Anyway steps are : 

1. create 1 EBS volume
2. attach this volume to your EC2 instance store 

3. format it as ext3
mkfs.ext3 /dev/sdf

4. mount it
mkdir /mnt/ebs
mount /dev/sdf /mnt/ebs

5. sync the instance with the volume
rsync -avHx / /mnt/ebs
rsync -avHx /dev /mnt/ebs

(you can edit /mnt/ebs/fstab and delete the reference towards the /mnt partition)

6. sync && umount /mnt/ebs

7. create a snapshot of that volume

8. register the ami based on that snapshot

ec2-register -s snap-ID -name "EBS instance" -description "EBS instance" -architecture i386

 -ramdisk ari-d23cd6bb -kernel aki-c43cd6ad

As a result it should show something like:

IMAGE   ami-newID
