Tell fio to only lay out files

["Georg Schönberger" <gschoenberger@thomas-krenn.com>]

Hello Everyone,

is it possible to tell fio to only lay out the data files and not carry
out any tests?
The thing is that I need to sync my Flashcache device after laying out
the files and before starting the read tests. Therefore it would be
helpful if I could do the following:
-Start fio and tell him to only lay out data files
-Sync my cache
-Start fio again with the previous layed out files and do the tests

Another option would be the parameter "filename", which tells fio to use
that file. But what if I am using multiple processes, can I specify a
file on command line for each process?

Thanks, Georg
