I got a similar error by running 'prelink -af' and 30c in tow simultaneous loops.</p> <p>Emoly,<br/> could you please have a look at this one?<br/> Thank you!</p> <p>Oleg suggests that the root problem is that the source <tt>/bin/sleep</tt> binary is being modified while the test is running, since we always run on a newly-installed system. One solution is probably to make a copy of <tt>/bin/sleep</tt> to some temporary location first, then copy from that temporary file into Lustre. Another solution is to do a checksum of /bin/sleep before the test and then not mark the test a failure if the checksum has changed since the test started.</p> <p>Emoly Liu (emoly.liu@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/14025" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/14025</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6345" title="sanity-hsm test_30c: Binary overwritten during exec" class="issue-link" data-issue-key="LU-6345"><del>LU-6345</del></a> test: compare /bin/sleep in sanity-hsm.sh test_30c<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 4236054300f2fe8cad18dcd24338c7096b41a8d8</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/14025/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/14025/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6345" title="sanity-hsm test_30c: Binary overwritten during exec" class="issue-link" data-issue-key="LU-6345"><del>LU-6345</del></a> test: compare /bin/sleep in sanity-hsm.sh test_30c<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 79020798bdcc09477b0b4d05b1d35e2432909aab</p> Development Rank 1|hzx7v3: Rank (Obsolete) 17760 Severity
