[users] Sysbench fileio size issue

[Jake G.]

Hi all,?

Im using sysbench to benchmark disk read write speeds for CentOS.

My fileio test size is 10 GB, however when run random write or random read tests. It should that only 156.25MB have been transferred.
How can I force this test to use the full 10GB?

This is my command:
Random Read
sysbench --test=fileio --file-total-size=10G --file-test-mode=rndrd run


Random Write

sysbench --test=fileio --file-total-size=10G --file-test-mode=rndwr run


Thank you for your help.

You probably have to disable disk write caching? I do not have a
solution, just an idea.
