After racer finishes some dd's are still left running on the client nodes. The test suite then stops because it complains about the mounts being busy so it can't unmount for the next test.</p> <p>This was fixed recently via a change to zconf_umount_clients (<a href="https://jira.whamcloud.com/browse/LU-452" title="b1_8 __ksymtab_obd_device_(free|alloc) causes a section mismatch" class="issue-link" data-issue-key="LU-452"><del>LU-452</del></a> change <a href="http://review.whamcloud.com/2015" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/2015</a>, Git hash 26bb579a96efced8825b63b84465334368ecc382). This was committed to master for 2.1.58 (i.e. before the 2.2 split), so it should be fixed.</p> <p>The zconf_umount_clients() function will now wait indefinitely for busy processes to finish using the filesystem, rather than pretending the unmount was successful and blindly continuing with the server shutdown (which will definitely block the client from ever unmounting correctly).</p> Development Rank 1|hzurzb: Rank (Obsolete) 2195 Severity
