Hi Eric,

You'll probably need to disable attribute caching.  From the doc[1]:

You may also find that you need to disable attribute caching in your 
filesystem.  In NFS this is done with the -noac mount option (Linux) or 
-actimeo=0 (Solaris).  The attribute cache can prevent Galaxy from detecting 
the presence of output files or properly reading their sizes.  Note that there 
is some performance trade-off here since all attributes will have to be read 
from the file server upon every file access.
