and then 'write' and 'read' job would be sharing those files. Let me
know if it works for you.
Thank you for patch Jens.
Re-using files working for me and i also like that string format
specification. Compiled with last git and tested on Mac OS X and
Centos 5.
I played with fio and sequence tests, it already helps me to get
figures much closer to real world utilization. I always struggled with
generic synthetic benchmarks as it usually don't work with sequences.
So i can roughly set IO sizes, modes, but for example can't simulate
performance differences caused by different file allocation between
one huge file (with few extents due to filesystem internal
optimization) and thousands of files.
Great!
Thanks for testing and confirming that it both works and that the
semantics make sense. I tagged 2.0.15 this morning and kept a few
pending features/fixes in a 'next' branch, all have been pulled into the
master branch. So the filename_format option is now in current -git,
though it did not make 2.0.15 final.
I too was able to compile the git version and try a test this morning
and it looks to be working just fine. This will help us immensely.
Thanks for the quick response and flexible solution!
