Issue

• Question is related more towards "how to cause/simulate a failure".
  Example:
  Let's say to simulate a mounted filesystem going read only while an application is running and using it. Similar to:

mount -o remount,abort /<some mount point

Also reading the documentation in kernel.org there reference to:

https://www.kernel.org/doc/Documentation/fault-injection/fault-injection.txt

Is there a way to enable this? Looking at what was compiled into the kernel, the option was not set, rather then re-compiling, is there a Red Hat tool that is available or recommended method to simulate failures.
