Description Ala Hino 2017-02-08 15:09:03 UTC 
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)
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 Nir Soffer 2017-02-22 19:54:33 UTC 
This is too risky for 4.1, please reschedule this for 4.2.
Comment 2 Allon Mureinik 2017-04-23 15:47:03 UTC 
The patches are abandoned, returning to NEW as a different solution should be designed.
