            <title>[SERVER-40207] sizeStorer.wt: encountered an illegal file format or internal value</title>
                <link>https://jira.mongodb.org/browse/SERVER-40207</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;My db instance crashed and after multiple attempts, is crashing as soon as i start it.&lt;/p&gt;

&lt;p&gt;This is the error that I&apos;m getting as soon as i start the mongod service. Running mongod --repair is giving me the same error.&lt;/p&gt;

&lt;p&gt;Starting mongodb with another blank dbpath works fine.&lt;/p&gt;

&lt;p&gt;Below are the log messages:&lt;/p&gt;

&lt;p&gt;Unfortunately we aren&apos;t able to repair this corruption.&lt;/p&gt;

&lt;p&gt;However, we can collect information to guide our development efforts in the future. If you are able, can you please provide:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;The complete logs for the affected node, including before, leading up to, and after the first sign of corruption.&lt;/li&gt;
	&lt;li&gt;A complete description of the underlying storage mechanism in use. Please address questions such as whether storage is locally attached or network-attached, whether disks are SSDs or HDDs, whether disks are SSDs or HDDs, whether RAID is in use and if so how it is configured, and what file system and/or volume management system is in use.&lt;/li&gt;
	&lt;li&gt;A description of your backup method, if any.&lt;/li&gt;
	&lt;li&gt;A history of the deployment, including:
	&lt;ol&gt;
		&lt;li&gt;a timeline of version changes&lt;/li&gt;
		&lt;li&gt;a timeline of hardware upgrade/downgrade cycles or configuration changes&lt;/li&gt;
		&lt;li&gt;a timeline of disaster recovery or backup restoration activities&lt;/li&gt;
		&lt;li&gt;a timeline of any manipulations of the underlying database files, including copies or moves, and information about whether mongod was running during each manipulation.&lt;/li&gt;
	&lt;/ol&gt;
	&lt;/li&gt;
	&lt;li&gt;Finally, can you provide assurances that you have not manipulated (copied or moved) the underlying database files while mongod was running, and that your disks have been recently checked for integrity?&lt;/li&gt;
&lt;/ol&gt;


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

&lt;p&gt;Danny&lt;/p&gt;</comment>

&lt;p/&gt;

&lt;p&gt;You mentioned that you have tried to run MongoDB with &lt;tt&gt;-&lt;del&gt;repair&lt;/tt&gt; and it did not succeed. Could you please download the &lt;a href=&quot;https://www.mongodb.com/download-center/community&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;4.0.6 MongoDB binaries&lt;/a&gt;, use the 4.0.6 binary to run the &lt;tt&gt;&lt;/del&gt;-repair&lt;/tt&gt; against your data files, and then start the &lt;tt&gt;mongod&lt;/tt&gt; using your original binaries?&lt;/p&gt;

&lt;p&gt;Thank you,&lt;/p&gt;
