First volume is resynced without any problems. But when second volume resync process is about 54% (probably, it is a range, when it is required to allocate new sectors on host OS for a virtual disk file?) system is... hanging. Totally. This is a 100% reproducable bug on my system. All logs attached.",defect,closed,virtual disk,VirtualBox 4.2.8,obsolete,"windows 2012, raid, mirror",,Windows,Windows
