If the default size of a launched Teradata Aster Analytics on AWS instance is insufficient, you can expand EBS storage volume capacity or attach additional EBS storage volumes to the instance. When adding EBS volumes, be sure to change the suggested default device name to prevent errors. After adding EBS volumes, use the lsblk command to view the unpartitioned volumes. Since Teradata Aster Analytics on AWS will not automatically use the volumes, you must also manually create any file systems on the volumes that you want to use. For more information on expanding and naming EBS storage volumes on AWS, see Amazon User Guide for Linux Instances.
