Did you configure and compile INN with large file support ?
(configure --enable-largefiles)

BTW, INN with CNFS appears to work better if you run it on a
file rather than on a partition - pagecache buffering under Linux
appears to be smoother than going through the buffercache.

As a workaround you can use ,
a mini-filesystem that shows a disk device as a single large file.
