@AlexPDX When I looked at this on the smartphone earlier today it did not load the second picture and so I misunderstood the issue. The master nodes sends a HTTP request (URL http://x.x.x.x/fog/status/freespace.php?path=/images) to the storage node to get that information. The storage node checks if the given path exists, is readable and a directory. If not it returns no values.
So your link /images -> /home/fogproject/images is causing the issue. Linking can be somewhat hideous and I would never advice anyone to link to the images directory just to mask that it was setup the wrong way in the first place.
I suggest you move all the content from /home/ to a temporary location, re-mount that partition (/dev/mapper/centos-home) into /images and move all the stuff you had in /home/fogproject/imagesover to the new/images` (residing on the extra partition.
