            <title>[SERVER-54876] Upgrade mongodb 4.4.4 from 4.2.12 failed</title>
                <link>https://jira.mongodb.org/browse/SERVER-54876</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hi,&lt;/p&gt;

&lt;p&gt;we&apos;ve a replica set with 6 nodes mongodb e one arbiter.&lt;/p&gt;

&lt;p&gt;I&#160; tried upgrade from 4.2.12 to 4.4.4 (rolling upgrade) and i did the following steps:&#160;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Upgrade from 4.2.12 to 4.4.2 one secondary node and the node it works perfectly in secondary mode.&lt;/li&gt;
	&lt;li&gt;switch primary from node 4.2.12 to 4.4.4 and the node 4.4.4 crashed.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;This is the output log trace before the node crash :&lt;/p&gt;

If an arbiter gets a durable optime/wall time at any point (which can happen if it goes into REMOVED while it has an oplog entry; there may be other bugs which can cause this), that optime will be passed to the other members of the set.  Even if the arbiter is subsequently restarted or even resynced, that durable optime will be greater than the (correct) null durable optime the arbiter is sending in heartbeats, so it will remain in the state of the other nodes in the system, which will pass it around using replSetUpdatePosition.&lt;/p&gt;

I have been able to create a reproduction of this bug but it requires a somewhat unusual sequence of events and I would like to confirm if it was possible before going forward.&lt;/p&gt;

&lt;p&gt;What would be required is that the arbiter was at one point not an arbiter, and wrote some oplog entries with a walltime of 0 (which could have happened in some previous versions).  Then it became an arbiter; we would continue to send that last oplog time as the last durable optime of the arbiter, which would crash a 4.4 node.&lt;/p&gt;

&lt;p&gt;So to check this, I would like to see if we can get the last entry in the oplog collection (local.oplog.rs) on the arbiter.  There really shouldn&apos;t be such a collection; if there isn&apos;t, that isn&apos;t the problem.&lt;/p&gt;</comment>

&lt;p&gt;All nodes have this output : &lt;/p&gt;

&lt;p&gt; db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )&lt;br/&gt;
{&lt;br/&gt;
 &quot;featureCompatibilityVersion&quot; : &lt;/p&gt;
{
 &quot;version&quot; : &quot;4.2&quot;
 }
&lt;p&gt;,&lt;br/&gt;
 &quot;ok&quot; : 1,&lt;br/&gt;
 &quot;$clusterTime&quot; : {&lt;br/&gt;
 &quot;clusterTime&quot; : Timestamp(1615988483, 684),&lt;br/&gt;
 &quot;signature&quot; : &lt;/p&gt;
{
 &quot;hash&quot; : BinData(0,&quot;EFp6D8mRrtb88nUTJ2zWtnX/SO0=&quot;),
 &quot;keyId&quot; : NumberLong(&quot;6919393090692186131&quot;)
 }
&lt;p&gt; },&lt;br/&gt;
 &quot;operationTime&quot; : Timestamp(1615988483, 683)&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

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

I have another question, what is the current &lt;tt&gt;featureCompatibilityVersion&lt;/tt&gt; on all 7 members of this replica set? To view the &lt;tt&gt;featureCompatibilityVersion&lt;/tt&gt; for a mongod instance, run the following command on each mongod instance:&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;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;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
