File vdsm/virt/vm.py:

Line 4923:         if res['info']['voltype'] == 'SHARED':
Line 4924:             self.log.error("merge: Refusing to merge into a shared 
volume")
Line 4925:             return errCode['mergeErr']
Line 4926: 
Line 4927:         ret = self._findAndsetDiskBlockJob(drive['path'], jobUUID, 
base, top)
We should probably use a specific exception here.
Line 4928:         if ret is False:
Line 4929:             self.log.error("Another block job is already active on 
this disk")
Line 4930:             return errCode['mergeErr']
Line 4931: 


Line 4933:             ret = self._dom.blockCommit(drive.path, base, top, 
bandwidth, 0)
Line 4934:             if ret != 0:
Line 4935:                 raise RuntimeError("blockCommit operation failed 
rc:%i", ret)
Line 4936:         except Exception:
Line 4937:             self.log.error("Live merge failed for '%s'", drive.path,
This is enough:

 self.log.exception("Live merge failed for '%s'", drive.path)
Line 4938:                            exc_info=True)
Line 4939:             self._findAndsetDiskBlockJob(drive['path'], None)
Line 4940:             return errCode['mergeErr']
Line 4941:
