You are welcome, and thanks for the screen capture.
As I mentioned in the instructions for using the lsof command, each line of the output specifies first what process has a file open. Most of your files are open by mds_store, or by notifyd. The issue of quitting notifyd is discussed in this Apple Support Forums thread:
discussions.apple.com/message/22716483
I have not found a detailed description of just what mds_store does. Some of the threads concerning it are about Spotlight or Time Machine. If you excluded the SSD2 volume from Spotlight and Time Machine, the files on it might close. That leaves a few more processes and its open files.
