Description of problem:
During live merge, base volume size is extended to maximum, i.e. by top volume size + vol-chunk-size. This is a worst case calculation.
After live merge completes we have to reduce base volume size.
Steps to Reproduce:
1. Run live merge (make sure you copy some data to the top volume)
Base is extended by top's size
Base to be extend by data in top volume +/- 1gb
This is too risky for 4.1, please reschedule this for 4.2.
The patches are abandoned, returning to NEW as a different solution should be designed.
