Sorry I wasn't reading the list for a few days and when I saw the  
problem you had I was like holy sh!t, I'm glad it turned out to be a  
non-issue.

Did defragging help?

Can you give me the layout of your disks, chunk size, how many (I  
think you said it was raid5?) so I can verify the sunit and swidth  
values are correct?
