From the log it appears converter agent wasn't able to determine first volume's file system:
2013-02-05T16:52:58.031+08:00 [08116 info 'task-1'] GetVolumeCloneMgr: filesystem type: <unknown>, source volume cluster size: 4096, target volume cluster size: 4096, source volume capacity: 41094144 bytes, target volume capacity: 41943040 bytes, resize requested: false.
Consequently the tracking for disk changes couldn't be started:
2013-02-05T16:52:58.031+08:00 [08116 info 'task-1'] BitmapBuilderCollection::ConsultModifiedClusterBitmap: the modified cluster bitmap will not be consulted for volume Disk#0_Partition#1
2013-02-05T16:52:58.031+08:00 [08116 error 'task-1'] BitmapBuilderCollection::ConsultUsedClusterBitmap: cannot consult the used cluster bitmap because this volume (Disk#0_Partition#1) does not support it
What is the fs type of that volume?
