            <title>[SERVER-24343] When PC reboot, mongodb is not shutdown cleanly, then mongodb failed to recover. Using WT storage engine</title>
                <link>https://jira.mongodb.org/browse/SERVER-24343</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Mongodb works fine at first.&lt;br/&gt;
Then PC reboots without shutting down the mongodb cleanly.&lt;br/&gt;
Then we try to start the mongod service again by the same command, it fails and return  &quot;dbexit:  rc: 100&quot;.&lt;br/&gt;
Also we&apos;re not able to repair the mongodb database.&lt;br/&gt;
We&apos;re using WiredTiger storage engine.&lt;br/&gt;
Attachment is the mongodb log containing the error messages.&lt;/p&gt;

To ensure a clean shutdown, please follow one of the methods listed.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;

For more details please see the &lt;a href=&quot;https://docs.mongodb.com/manual/administration/production-notes/#production-notes&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB Production Notes&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;According to your comments, database will be probably corrupted in the event of a power loss for XFS. &lt;br/&gt;
What about the manual reboot?&lt;/p&gt;

&lt;p&gt;Thanks,&lt;/p&gt;</comment>
                            <comment id="1281349" author="ramon.fernandez" created="Wed, 1 Jun 2016 17:34:50 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=litmus&quot; class=&quot;user-hover&quot; rel=&quot;litmus&quot;&gt;litmus&lt;/a&gt;, you may try to run &lt;tt&gt;mongod --repair&lt;/tt&gt;, but please note the following:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;I&apos;d strongly suggest you make a backup copy of your corrupt files before you try any operations&lt;/li&gt;
	&lt;li&gt;While I can&apos;t make a general statement, in my experience XFS may not behave well in the event of a power loss and using a UPS is highly recommended &amp;#8211; specially if &lt;a href=&quot;https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/ch-writebarriers.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;write barriers&lt;/a&gt; are disabled. Is this your case?&lt;/li&gt;
	&lt;li&gt;If you upload your &lt;tt&gt;WiredTiger.wt&lt;/tt&gt; and &lt;tt&gt;WiredTiger.turtle&lt;/tt&gt; files we can do a repair attempt, but the signs point to unrecoverable corruption so you should consider recovering from backups and using a replica set&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;That being said, please note that the SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt; or &lt;a href=&quot;http://stackoverflow.com/questions/tagged/mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Stack Overflow with the &lt;tt&gt;mongodb&lt;/tt&gt; tag&lt;/a&gt;, where your question will reach a larger audience.&lt;/p&gt;

&lt;p&gt;I&apos;ll keep the ticket open a bit longer if you want to explore the repair attempt but, in the future, a question like this involving more discussion would be best posted on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt;. See also our &lt;a href=&quot;https://www.mongodb.org/about/support/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Technical Support page&lt;/a&gt; for additional support resources.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
