&lt;p&gt;Thanks for confirming the repair was successful.  I&apos;m now closing this issue.&lt;/p&gt;

&lt;p&gt;Please close &lt;/p&gt;</comment>

&lt;p&gt;Do you have any update on this issue?  Were you able to successfully continue operations after repairing the shards?&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;
Stephen&lt;/p&gt;</comment>
                            <comment id="462513" author="eliot" created="Wed, 27 Nov 2013 05:03:05 +0000"  >&lt;p&gt;Its hard to check for all possible disk corruption without scanning the entire database, so not sure the best solution.&lt;/p&gt;

&lt;p&gt;Do you have backups from before the SAN problem?&lt;/p&gt;</comment>
                            <comment id="462506" author="ilasic" created="Wed, 27 Nov 2013 04:26:45 +0000"  >&lt;p&gt;Yes there is a definite possibility Mongo files were corrupted&lt;/p&gt;

&lt;p&gt;That being said db should have detected the corruption on load and not&lt;br/&gt;
leave me in a lurch&lt;/p&gt;

                            <comment id="462485" author="eliot" created="Wed, 27 Nov 2013 02:59:03 +0000"  >&lt;p&gt;What kind of SAN failure?&lt;br/&gt;
Is possible the SAN corrupted the mongo files?&lt;/p&gt;</comment>
                            <comment id="462473" author="ilasic" created="Wed, 27 Nov 2013 02:46:44 +0000"  >&lt;p&gt;I have a lot of query logging that is sensitive to share. If  I strip that&lt;br/&gt;
out will the log be useful?&lt;/p&gt;

&lt;p&gt;BTW this started after San failure.&lt;/p&gt;

&lt;p&gt;I did mongodb repair on my shards and am rerunning my processing to see if&lt;br/&gt;
crash happens again.&lt;/p&gt;

Also, can you check the system log for io errors?&lt;/p&gt;</comment>
