I will ignore the "server" part...

If the original filename contained .-1 somewhere, you're modifying it.  
This is safer and shorter:

import os,string
filename = "whoa.mp3"
dir_path = "/u01/"
ofilename = filename
i = 0
while os.path.exists(dir_path+filename):
  filename = "%s.-%s" % (ofilename,i)
  i += 1
req.write(filename)
