README

        
Currently the read hammer test will run for 14 days ( 336 hours) after the SSDs

are prepared.  Increase the number of run cycles in the "readhammer" workload

profile file to run the test for longer.

Use the following steps to run the readhammer test.

1. Precondition a single device:

  fb-FioSynthFlash -d /dev/sdc -w prep -f precondition

  or

   Precondition all devices:

  fb-FioSynthFlash -d ALL -w prep -f precondition

2. Run readhammer test on a single device:

  fb-FioSynthFlash -d /dev/sdc -w readhammer -f readhammer

  or

   Run readhammer test on all devices:

  fb-FioSynthFlash -d ALL -w readhammer -f readhammer

3. All results are stored in a .csv file in the specified results directory.

Note:  If you are running the read hammer test on more than one device, it

  is recommended to increase the maximum number of active aio contexts.

   echo "262144" > /proc/sys/fs/aio-max-nr
