Routines responsible for polling of in-progress pvmove, snapshot merge or mirror conversion each used custom lookup functions to find vg and lv involved in polling. Especially pvmove used pvname to lookup pvmove in-progress. The future lvmpolld will poll each operation by vg/lv name (internally by lvid). Also there're plans to make pvmove able to move non-overlaping ranges of extents instead of single PVs as of now. This would also require to identify the opertion in different manner. The poll_operation_id structure together with daemon_parms structure they identify unambiguously the polling task.
