size

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. Constraints: 1-16,384 for gp2, 4-16,384 for io1 and io2, 500-16,384 for st1, 500-16,384 for sc1, and 1-1,024 for standard. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size. Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.
