In the last days I spent some time to take care of some AWS instances, and I ported one of this from instance-store to EBS, so the whole server is persistent and can be restarted without any data loosing.
- Start ad instance-store machine, modify as you like.
- Create a Volume with the size of 10GB and attach it to instance (suppose that it will be /dev/sdf).
format it as EXT3
mount /dev/sdf /mnt/ebs
sync the instance with the volume
rsync -avHx / /mnt/ebs
rsync -avHx /dev /mnt/ebs
flush and umount
- detach the volume and create a snapshot
register the AMI
ec2-register --region $REGION -s $SNAP –name $NAME –description “$DESC” –architecture $ARCH --root-device-name /dev/sda1 --block-device-mapping '/dev/sda2=ephemeral0' --block-device-mapping '/dev/sda3=ephemeral1'
change the appropriate parameter with your own
Now you have a fresh EBS AMI ready to boot into a new instance.
