Amazon EBSのボリュームを自動でattachしてマウントしたい – cyberarchitect
を参考にさせて頂き試してみましたがエラーが…。＞＜
『Client.InvalidVolume.NotFound: The volume ‘vol-XXXXXXXX’ does not exist.』
リージョンの設定が足りないようだったので。
Scripts to automatically attach and mount an EBS Volume at Boot Time
のスクリプトを改造して、ec2-attach-volume コマンドに –region のオプションを追加した。

※ ec2-detach-volume するときに unmount しないとうまくいかなかったのでそれも追加した。
.ec2cred に
