After a few days, the MDS started crashing and now crashes every time I mount the MDT after the recovery is finished. this looks similar to the crash reported in <a href="https://jira.whamcloud.com/browse/LU-5040" title="kernel BUG at fs/jbd2/transaction.c:1033" class="issue-link" data-issue-key="LU-5040"><del>LU-5040</del></a>, that's why I have applied the patch from that issue to my server. I have also added the patch from <a href="https://jira.whamcloud.com/browse/LU-5777" title="reserve enough credits for chown/chgrp operation" class="issue-link" data-issue-key="LU-5777"><del>LU-5777</del></a>, but the crash is the same.</p> SL6.6 LU-6552
