&lt;p&gt;I have attached &lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/attachment/136022/136022_repair_attempt-2.tar.gz&quot; title=&quot;repair_attempt-2.tar.gz attached to SERVER-25525&quot;&gt;repair_attempt-2.tar.gz&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://jira.mongodb.org/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt; for the backup files you uploaded. As before, please place these files in your backup&apos;s &lt;tt&gt;$dbpath&lt;/tt&gt; and restart the mongod.&lt;/p&gt;

&lt;p&gt;If this repair attempt does not resolve the issue, I would recommend posting 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-users group&lt;/a&gt;, and providing the latest logs after starting with &lt;tt&gt;--repair&lt;/tt&gt; using the files I have provided. The mongodb-users group provides a forum for MongoDB-related support discussion, and users there may be able to suggest additional steps to recover data. In this situation, please understand that a complete recovery would be unlikely.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;

Thanks very much! &lt;br/&gt;
1:the log is quite big(35G).last day the log which i upload is a little , and the new_mongod.log is the log i have selected from the 35G .&lt;br/&gt;
2:yes , i mv WiredTiger.wt to other place , and i restart the service(./bin/mongod/ --dbpath=... --logpath=... --port=27017 --fork), and it&apos;s start successly. and  produce a new WiredTiger.wt WiredTiger.turtle in the dbpath. use the old  WiredTiger.wt(16M) i can&apos;t start the service, so i think the Service exception is about WiredTiger.wt&#12290;&lt;br/&gt;
3&#65306;yes, we have a backup system,but the backup system also reboot, and it&apos;s also can&apos;t be start correctly! (sorry,my Colleague and i not familiar with mongodb,maybe Some mistakes were made in the process&#65289;.&lt;br/&gt;
4.the attachment is the mongod.conf,and WiredTiger.turtle,the WiredTiger.wt(16 M i already uploaded!)&lt;br/&gt;
5: i want your guys help us repair WiredTiger.wt WiredTiger.turtle , thank you !&lt;br/&gt;
finally , your guys so nice! &lt;/p&gt;</comment>
                            <comment id="1353424" author="ramon.fernandez" created="Wed, 10 Aug 2016 21:23:56 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=ao.zhang&quot; class=&quot;user-hover&quot; rel=&quot;ao.zhang&quot;&gt;ao.zhang&lt;/a&gt;, sorry you&apos;ve run into this issue. From the list of steps you tried above and the logs you uploaded I&apos;m not sure this is a recoverable situation, but I&apos;d like to ask some more questions to be sure:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Are these all the logs you have? The logs you uploaded seem to be missing important pieces, like messages from the startup sequence or information about some of the steps you described above&lt;/li&gt;
	&lt;li&gt;The &lt;tt&gt;WiredTiger.wt&lt;/tt&gt; file is an important one, and it should not be removed from the &lt;tt&gt;dbpath&lt;/tt&gt;. Did you move/delete any other files in the &lt;tt&gt;dbpath&lt;/tt&gt;&lt;/li&gt;
	&lt;li&gt;Do you have a backup of your data prior to the unexpected shutdown? By removing the &lt;tt&gt;WiredTiger.wt&lt;/tt&gt; the &lt;tt&gt;repair&lt;/tt&gt; operation may have further damaged your data. At this stage the easiest way forward is to restore this node from a healthy primary or from a data backup.&lt;/li&gt;
	&lt;li&gt;Can you please upload your &lt;tt&gt;/home/work/ichartmongodb/mongodb/conf/mongod.conf&lt;/tt&gt; file?&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;If I&apos;m not mistaken, the only thing we can try is to attempt a repair of your &lt;b&gt;original&lt;/b&gt; &lt;tt&gt;WiredTiger.wt&lt;/tt&gt; file (the 16MB one) and the &lt;tt&gt;WiredTiger.turtle&lt;/tt&gt; file (the ones you moved to &lt;tt&gt;/home/work/lei.zhang/new/now&lt;/tt&gt;). If you upload them here we can attempt a repair, but there&apos;s no guarantee that it will work.&lt;/p&gt;

&lt;p&gt;Please let us know how you want to proceed.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
Ram&#243;n.&lt;/p&gt;</comment>
