I played around with this about a month back during a rados bench run,
but had some trouble getting it to work when strace was attached to an
already running process. I didn't end up spending a lot of time on it
though. Jeff Layton also wrote a strace analyzer tool specifically for
IO, but it needs a bit of work to support -f. His stuff can be found here:

Hi Mark,
I am the developer of the ioreplay app (ioapps suite). I came across this post,
could you please provide more details on the problem with replaying of
"incomplete" strace files? It is certainly possible that there is a bug as this
functionality was not thoroughly tested. I willing to fix it and help you with
that. Your sample strace file + ignore/map files + arguments would help.
Cheers
