Re: Periodic sync?

fsync=int       If writing to a file, issue a sync of the dirty data
                 for every number of blocks given. For example, if you give
                 32 as a parameter, fio will sync the file for every 32
                 writes issued. If fio is using non-buffered io, we may
                 not sync the file. The exception is the sg io engine, which
                 synchronizes the disk cache anyway.



This should help you.

Thanks,
