Lustre 1.6 Operations Manual

16.2 Running POSIX Tests Against Lustre
To run the POSIX tests against Lustre:
1. As root, set up your Lustre filesystem, mounted on /mnt/lustre (for instance, sh
llmount.sh) and untar the POSIX tests back to their home.
$ tar --same-owner -xzpvf /path/to/tarball/TESTROOT.tgz -C \
/mnt/lustre
As the vsx0 user, you can re-run the tests as many times as you want. If you are
newly logged in as the vsx0 user, you need to source the environment with '.
profile' so that your path and environment is set up correctly.
2. Run the POSIX tests, run:
$ . /home/tet/profile
$ tcc -e -s scen.exec -a /mnt/lustre/TESTROOT -p
New results are placed in new directories at /home/tet/test_sets/results
Each result is given a directory name similar to 0004e (an incrementing number
which ends with e (for test execution) or b (for building tests).
3. To look at a formatted report, run:
$ vrpt results/0004e/journal | less
Some tests are "Unsupported", "Untested" or "Not In Use", which does not
necessarily indicate a problem.
4. To compare two test results, run:
$ vrptm results/ext3/journal results/0004e/journal | less
This is more interesting than looking at the result of a single test as it helps to
find test failures that are specific to the filesystem, instead of the Linux VFS or
kernel. Up to six test results can be compared at one time. It is often useful to
rename the results directory to have more interesting names so that they are
meaningful in the future.
