Application for monitoring LVM volumes and moving blocks based on usage to 
higher or lower tier storage.

to compile:
make

lvmtsd is used like this:
./lvmtsd /dev/vol-grp00/log-vol00

It will dump collected data (including 200 most active, most written and most
read blocks in format ready to use with pvmove) when the pipe is broken (killall
blktrace) and every 5 minutes.

there is one optional parameter, the number of extents written in status 
information:
./lvmtsd <lv-dev-path> [<number-of-extents>]
for example:

./lvmtsd /dev/VolGrp00/LogVol01 400
