[Gluster-devel] Relocating the namespace brick

I did see the same problem even after remounting the client. I moved the 
namespace files back to the original location, and things worked again -- 
evidently you can't just move the namespace files. The other thing I did was 
point the brick to a soft link. What is the correct procedure to move 
namespace files?
