Hi, _for_each_pv() is a function to walk through all PVs used by given part of LV. The function is expected to set smallest length of PV segment consists of the part of LV. However, current code doesn't work as expected. As a result, build_parallel_areas_from_lv() considers only the first segment of the LV and fails to build appropriate list of PVs to be avoided. Attached patch fixes this problem. Applicable to 2.02.09. Thanks, -- Jun'ichi Nomura, NEC Corporation of America
