Description Ala Hino 2017-02-08 15:05:22 UTC 
Description of problem:
During cold merge, base volume size is extended to maximum, i.e. by top volume size + vol-chunk-size. This is a worst case calculation.
After cold merge completes we have to reduce base volume size.

Steps to Reproduce:
1. Run cold merge
2.
3.

Actual results:
Base is extended by top's size

Expected results:
Base to be extend by data in top volume +/- 1gb
Comment 1 Carlos Mestre González 2017-04-28 17:23:07 UTC 
Checked multiple cold merges, base volume is extended by 1gb chunks
