I'm trying to use the Linux fault injection framework to inject page allocation faults. I'm trying to use the failcmd.sh script provided with the Linux kernel in tools/testing/fault-injection/.

After setting variable FAILCMD_TYPE to fail_page_alloc, I'm running the following command:

./failcmd.sh --times=-1 --interval=1 --verbose=2 <program_to_be_run_with_fi>.

All programs I have tried this with have run fine and I do not get any debug information back although I set verbose to 2. I'm using kernel 3.2.0-32 on Ubuntu 12.04.1.

Does anyone have experience with fault injection in Linux?

Did you configure the kernel with `fault-injection` enabled? It won't work without kernel support. You cann't use a stock Linux kernel. – artless noise Feb 24 '13 at 00:19
Have you tried asking your question on http://unix.stackexchange.com/ ? – Agi Hammerthief May 18 '13 at 12:48
