            <title>[SERVER-2010] --repair fails with: Assertion failure magic == 0x41424344 db/pdfile.h 239</title>
                <link>https://jira.mongodb.org/browse/SERVER-2010</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;My system crashed, and I saw the following error when I tried to repair my MongoDB database. I&apos;m going to try to keep a copy of the corrupted database around for a while in case you need it.&lt;/p&gt;

&lt;p&gt;Note that the database in question wasn&apos;t vital; I had used it months ago for benchmarking GridFS. And I have no idea why mongod thinks it needs to upgrade anything&#8212;I haven&apos;t touched my MongoDB installation in the last several reboots, and I&apos;ve been running it continuously.&lt;/p&gt;

&lt;p&gt;$ mongod --version&lt;br/&gt;
db version v1.6.0, pdfile version 4.5&lt;br/&gt;
Tue Oct 26 16:01:55 git version: nogitversion&lt;/p&gt;

Tue Oct 26 15:27:48 MongoDB starting : pid=729 port=27017 dbpath=/data/db/ 32-bit &lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;ul&gt;
		&lt;li&gt;NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data&lt;/li&gt;
		&lt;li&gt;see &lt;a href=&quot;http://blog.mongodb.org/post/137788967/32-bit-limitations&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://blog.mongodb.org/post/137788967/32-bit-limitations&lt;/a&gt;&lt;/li&gt;

12-19 was large and correct.&lt;br/&gt;
01-07 was blank.&lt;/p&gt;

&lt;p&gt;Blank wouldn&apos;t be caused by a crash, so not sure where that came from.&lt;/p&gt;</comment>

&lt;p&gt;Are you sure they were both small?&lt;/p&gt;

That&apos;s what you would get if you started with a clean database.&lt;/p&gt;

&lt;p&gt;The .ns file looks correct, but the .0 and .1 are from an empty db.&lt;/p&gt;

&lt;p&gt;If those were from a kill -9, we might expect some garbage data, but nothing would 0 the files out.&lt;/p&gt;</comment>

Any sort of crash can&apos;t zero out the entire file.&lt;/p&gt;

&lt;p&gt;Can you do&lt;/p&gt;

&lt;p&gt;hexdump imeveryone.0 &lt;br/&gt;
and send the output&lt;/p&gt;</comment>

Were those taken right after the crash?&lt;/p&gt;</comment>
                            <comment id="22200" author="mikemaccana" created="Sun, 9 Jan 2011 23:37:59 +0000"  >&lt;p&gt;Thanks Eliot,&lt;/p&gt;

&lt;p&gt;I&apos;ve reuploaded the files:&lt;br/&gt;
Corrupt DB is : corruptdb-2011-01-07.tgz&lt;br/&gt;
Working backup is : db-2010-12-19.tgz&lt;/p&gt;

&lt;p&gt;mongod on the server where the problem happened was 1.4.4 on Linux, per&lt;br/&gt;
mongo-users I&apos;ve tried repair tools all the way up to 1.7.4 on OS X.&lt;/p&gt;

&lt;p&gt;Mike&lt;/p&gt;

&lt;p&gt;I&apos;ve reuploaded the files:&lt;br/&gt;
Corrupt DB is : corruptdb-2011-01-07.tgz&lt;br/&gt;
Working backup is : db-2010-12-19.tgz&lt;/p&gt;

&lt;p&gt;mongod on the server where the problem happened was 1.4.4 on Linux, per mongo-users I&apos;ve tried repair tools all the way up to 1.7.4 on OS X.&lt;/p&gt;

                            <comment id="22196" author="eliot" created="Sun, 9 Jan 2011 21:23:35 +0000"  >&lt;p&gt;@mike, if you could upload an old backup and absolutely any logs would help a lot.&lt;/p&gt;

&lt;p&gt;also, can you tell us exactly what the files upload were.&lt;br/&gt;
something seems off of about them that I wouldn&apos;t expect.&lt;/p&gt;</comment>

&lt;p&gt;I have SCPd a tarball to www.10gen.com:corruptdb.tgz . Any help would be sorely appreciated!&lt;/p&gt;</comment>

How big is the raw data?&lt;br/&gt;
Can you try --repair on a 64-bit machine?&lt;/p&gt;

&lt;p&gt;To send us privately you can:&lt;/p&gt;

&lt;p&gt;scp -P 722 &amp;lt;file&amp;gt; &amp;lt;any username&amp;gt;@www.10gen.com:&lt;/p&gt;

&lt;p&gt;&amp;lt;any password&amp;gt;&lt;/p&gt;

&lt;p&gt;then comment with the username you used&lt;/p&gt;</comment>
