man lvmsadc: 
       lvmsadc collects the read/write statistics of the  logical
       volume  manager  to the file "LogFilePath" or to stdout if
       no LogFilePath is given.  You should create a  cron  entry
       for lvmsadc which runs it at regular intervals eg. 10 min­
       utes.

That statistical info can be later used to e.g. decide which
LEs shoud have PEs at the faster 'begin' (outer edge) of the
HD.  An automatic LE mover program has not been written yet.
