Reasons:
- There are two attributes coming from trove related to volume
attached, total size of volume and used space of volume.
- Used space is an important attribute for a user, it would help to
plan the resize of volume before the attached volume gets finished.
Changes:
- Adds display of used volume attribut, with "trove show" command.
- Avoids display in dicts-form.
- do_show method now displays total space, and used space for the
atttached volume, as
| status | ACTIVE |
| updated | 2014-01-12T22:17:20 |
| volume | 1 |
| volume_used | 0.13 |
