As i checked there's nothing to be write except log file's. Memory usage, CPU utilization all are normal state.

From "atop -d, sar, iostat, dstat " i just got a point that 99% of writing process on hard-disk by mysql. but still unable to get detail which mysql query or other process increase this.

If it is mysql, try this https://dev.mysql.com/doc/refman/5.1...ocesslist.html
