Description
Following resolution of bug LU-5933, I tried to run fiemap-tester from xfstests, and saw it fail. I don't know whether it's a Lustre or some bad assumption, but the same test works fine on ext4, and presumably all filesystem supported by the xfs test suite.
xfstests is easy to get and install. See http://xfs.org/index.php/Getting_the_latest_source_code. fiemap-tester will fail within seconds, with no particular parameter besides the name of a file on Lustre.
