            <title>[SERVER-53300] WiredTiger error on Startup</title>
                <link>https://jira.mongodb.org/browse/SERVER-53300</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hello! After a power shortage we are not able to get our mongoDB database online anymore.&#160;&lt;/p&gt;

&lt;p&gt;It&apos;s huge database with .wt file of 200MB.&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Is there any chance to recover this DB?&lt;/p&gt;

&lt;p&gt;Best,&lt;/p&gt;</comment>

&lt;p&gt;We still need additional information to diagnose the problem. If this is still an issue for you, would you please let us know the results of --repair?&lt;/p&gt;

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

                            <comment id="3533640" author="eric.sedor" created="Wed, 16 Dec 2020 23:16:06 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=rodrigo.cadena%40eletromidia.com.br&quot; class=&quot;user-hover&quot; rel=&quot;rodrigo.cadena@eletromidia.com.br&quot;&gt;rodrigo.cadena@eletromidia.com.br&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;MongoDB 3.4 &lt;a href=&quot;https://www.mongodb.com/support-policy&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;reached end of life in January of 2020&lt;/a&gt;. But we can provide limited guidance on this issue. The ideal resolution is to perform a clean &lt;a href=&quot;https://docs.mongodb.org/manual/tutorial/resync-replica-set-member/#automatically-sync-a-member&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;resync&lt;/a&gt; from an unaffected node.&lt;/p&gt;

&lt;p&gt;First, make a complete copy of the database&apos;s $dbpath directory to safeguard so that you can work off of the current $dbpath. Then, try &lt;a href=&quot;https://docs.mongodb.com/manual/reference/program/mongod/#cmdoption-mongod-repair&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;mongod --repair&lt;/tt&gt;&lt;/a&gt; using the latest version of MongoDB.&lt;/p&gt;

&lt;p&gt;Sincerely,&lt;br/&gt;
Eric&lt;/p&gt;</comment>
