            <title>[SERVER-9818] Problems when starting MongoDB with &gt; 1023 FDs</title>
                <link>https://jira.mongodb.org/browse/SERVER-9818</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When running a 3 node replSet with lots of data and currently and have more than 1500 datafiles, you got the following error messages at restart.&lt;br/&gt;
It looks like it has something to do with a FD_SETSIZE limitation to 1024. But ulimit -n is set correctly (ulimit -n 550000).&lt;/p&gt;

&lt;p&gt;This bug might correspond to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-8515&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-8515&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Even in standalone mode I believe that mongod will still try to open all these local database files.  If that procedure does work for you, let us know, and if doesn&apos;t, also let us know and we can walk you through the process of using mongodump and mongorestore.&lt;/p&gt;

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

&lt;p&gt;First of all, thanks for your support! We&apos;re currently decreasing the oplogSize and try to start over with a fresh local-db as described in &lt;a href=&quot;http://docs.mongodb.org/manual/tutorial/change-oplog-size/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/tutorial/change-oplog-size/&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This should fix our problem for now, i think. &lt;/p&gt;

&lt;p&gt;Thanks again and cheers,&lt;br/&gt;
Oliver   &lt;/p&gt;</comment>

&lt;p&gt;By default, MongoDB preallocates the oplog as a function of disk size.  You can change this using the --oplogSize option to mongod.  See &lt;a href=&quot;http://docs.mongodb.org/manual/reference/configuration-options/#oplogSize&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/reference/configuration-options/#oplogSize&lt;/a&gt; for more details on this.  This unreasonable default for the oplog size will be fixed as &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-9876&quot; title=&quot;cap the default initial oplog size&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-9876&quot;&gt;&lt;del&gt;SERVER-9876&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Have you inserted any data yet?  Can you just wipe the data directories and start over?  If not, let us know and we can walk you through the dump restore process.&lt;/p&gt;

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

&lt;p&gt;thank you very much for your detailed answer.&lt;br/&gt;
We do not store any big information in the local database. When starting MongoDB on the 50TB HDD, the local database files were created / allocated automatically.&lt;/p&gt;

&lt;p&gt;Is it possible to circumvent this behaviour?&lt;/p&gt;

&lt;p&gt;Thanks and kind regards,&lt;/p&gt;

&lt;p&gt;Tim&lt;/p&gt;</comment>
                            <comment id="355307" author="sverch" created="Fri, 7 Jun 2013 14:37:13 +0000"  >&lt;p&gt;Hi Oliver,&lt;/p&gt;

&lt;p&gt;It appears that the database that has many data files for your system is the local database.  While you can store information here, mongodb also uses the local database for metadata and handles it differently from other databases.  What are you storing in the local database?&lt;/p&gt;

&lt;p&gt;One thing you can do to get around this issue is to run mongodump in &quot;direct client&quot; mode.  This will interact with the data files directly without actually starting up the server:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongodump --dbpath &amp;lt;path to your data files&amp;gt; -c &amp;lt;collection name&amp;gt; -d local &amp;lt;name of dump destination&amp;gt;&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Then, you can restore all your data into a different database using the mongorestore command.&lt;/p&gt;

&lt;p&gt;With a mongod instance running:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongorestore --host &amp;lt;hostname&amp;gt; --port &amp;lt;port&amp;gt; -c &amp;lt;collection name&amp;gt; -d &amp;lt;db name&amp;gt; &amp;lt;name of collection file&amp;gt;&lt;/span&gt;&lt;/pre&gt;

		&lt;/tr&gt;

&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Without a mongod instance running:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongorestore --dbpath &amp;lt;path to your data files&amp;gt; -c &amp;lt;collection name&amp;gt; -d &amp;lt;db name&amp;gt; &amp;lt;name of collection file&amp;gt;&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Quick example:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongodump --dbpath /data/db/ -c coll -d local dump/&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongorestore --dbpath /data/newdb/ -c coll -d newdb dump/local/coll.bson&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;You can also adapt this to dump/restore the entire local database.&lt;/p&gt;

&lt;p&gt;The deeper issue here will be solved when our call to select is replaced as part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-2114&quot; title=&quot;Don&amp;#39;t use select timeouts for fast coarse timing&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-2114&quot;&gt;&lt;del&gt;SERVER-2114&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;We are having some issues reproducing the problem in this ticket.  Could you try running mongod with the -vvvvv option and post the output?  That would give us more information about what files the database is opening on startup.&lt;/p&gt;

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

&lt;p&gt;We are working on a reproduction of the issue.  We&apos;ll post updates as we have them.&lt;/p&gt;

&lt;p&gt;In the meantime, it would be helpful if you also posted some details about your environment.&lt;/p&gt;

&lt;p&gt;In particular:&lt;/p&gt;

&lt;p&gt;1. Number of data files you have&lt;br/&gt;
2. Log output from when you attempted to start up&lt;/p&gt;

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

&lt;p&gt;could you please give an update on the current ticket status. We are also experiencing the same issue in our production environments.&lt;/p&gt;

&lt;p&gt;Thank you very much and kind regards,&lt;/p&gt;
