<ul><li><strong>Subject</strong> changed from <i>MDS crush: thread_name:ms_dispatch</i> to <i>MDS crashes with log disabled</i></li><li><strong>Description</strong> updated (<a title="View differences" href="/journals/85928/diff?detail_id=82988">diff</a>)</li></ul><p>For some reason we still let people disable the MDS log. That's...bad. I think it only existed for some cheap benchmarking a decade ago and the config option should get thrown out.</p>
<p>Not sure why either of you were testing with this option, but I'm quite sure that's the problem and you shouldn't bother. :)</p>
