-size=siint The total size of file io for this job. This may describe
- the size of the single file the job uses, or it may be
- divided between the number of files in the job. If the
- file already exists, the file size will be adjusted to this
- size if larger than the current file size. If this parameter
- is not given and the file exists, the file size will be used.
+fadvise_hint=bool By default, fio will use fadvise() to advise the kernel
+ on what IO patterns it is likely to issue. Sometimes you
+ want to test specific IO patterns without telling the
+ kernel about it, in which case you can disable this option.
+ If set, fio will use POSIX_FADV_SEQUENTIAL for sequential
+ IO and POSIX_FADV_RANDOM for random IO.
+
+size=siint The total size of file io for this job. Fio will run until
+ this many bytes has been transferred, unless runtime is
+ limited by other options (such as 'runtime', for instance).
+ Unless specific nr_files and filesize options are given,
+ fio will divide this size between the available files
+ specified by the job.
