If an EBS volume is the root device of an instance, you must stop the instance before you can detach the volume. Write the data randomly instead of sequentially. Also, strongly consider using EBS optimized volumes where you can request the number of IOPS you need for your Next steps partition and format the drive - and this is where Ansible's idempotence comes really handy, since if the volume already has the partition setup as required - nothing gets changed or formated (if you try to run this over a volume with a different partition setup the steps will fail): volume_id - (Required) ID of the Volume to be attached; force_detach - (Optional, Boolean) Set to true if you want to force the volume to detach.
