[Test Case] * ocfs2_reproducer.sh (attached to this bug) [Regression Potential] * it could cause ocfs2 issues, so I guess its a low impact considering amount of users. * Its a straightforward fix identified by upstream developer and a clean cherry-pick for us. [Other Info] * Original description: I noticed the tests for ocfs2-tools/1.8.6-1ubuntu1 were constantly retrying themselves. It's a feature we have so that transient / occasional failures are auto-retried, but it's misfiring here because we're not detecting that it's a consistent failure. That particular bug is fixed, but it means that ocfs2-tools is failing on ppc64el. Here's the important part of the log, full output attached.
