I think the significant activity is this:

After 200 seconds idle (A):

After 154 seconds idle (D):

<7>[317128.917441] log_tool(12461): dirtied inode 13282 (event.log) on md9

In (A) and (C) there are references to vg1.log and vg2.log. These seem to be associated with valgrind (a debugging tool). Is it possible that the QTS 4.1 beta firmware contains valgrind debugging code that is writing to these log files? Can you look at these log files to see what they contain?
