Your architecture may also hit a problem with the tests. Here are some notes I had with the fallocate tests from a few months back that may interest you: On a couple of architectures (arm, mips) that the original authors never tested on, fallocate calls are returning EFBIG (file too large) rather than EOPNOTSUPP(not supported) like they are on pcc, and x86 architectures. I've run it on x86_64 Ubuntu 9.04 with an ext4 system, and the tests also seem to fail with EFBIG, when they should pass AFAICT. -- Henry Yei <hyei@mvista.com> ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Rahul, I never ran into this issue on i686, mips*, ppc, or x86_64 when I used to run these tests to validate releases, but I haven't actively run LTP for several months, and my environment most likely varied from your's. For starters, read the note about EFBIG for fallocate(2): http://www.kernel.org/doc/man-pages/online/pages/man2/fallocate.2.html . After you've done that, do some additional research to solve your problem: 1. Consider where the file is being is being created (hint: if you haven't defined $TMPDIR, it's /tmp). Consider what filesystem that directory is running. 2. Determine what the size of the file is that's being created (compile the application with -g, run with gdb, determine the size, etc). 3. Try creating the file with that size. Does step 3. pass or fail? Once you have these bits, please provide us with the details as well as your kernel version, architecture, etc. We can give you the answer or teach you how to fish. I think that teaching you how to fish is more worthwhile than fishing for you, especially when LTP is a group of volunteers interested in testing on Linux, not a support group. We can help you solve your problem if you get stuck, but please do the initial legwork to help us help you.
