            <title>[SERVER-31599] Only allow rollbackViaRefetchNoUUID method when in FCV 3.4</title>
                <link>https://jira.mongodb.org/browse/SERVER-31599</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently we allow selection of the rollback algorithm to use by means of the &apos;rollbackMethod&apos; server parameter. We should only allow the &apos;rollbackViaRefetchNoUUID&apos; to be used when a node is in FCV=3.4, and only allow the rollbackViaRefetch&apos; algorithm when the node is in FCV=3.6. This may involve removing the &apos;rollbackMethod&apos; server parameter, since the algorithm will be bound to FCV, instead of being user selectable.&lt;/p&gt;</description>

&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;python buildscripts/resmoke.py --basePort=43210 --mongodSetParameter=&quot;{rollbackMethod: rollbackViaRefetchNoUUID}&quot; jstests/replsets/rollback_ddl_op_sequences.js&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;the rollback node will fail with the following message:&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;Rollback cannot complete at this time (retrying later): InvalidOptions: Attempt to assign UUID to replicated collection: foo.b appliedThrough= { ts: Timestamp 1509636890000|21, t: 2 } minvalid= { ts: Timestamp 1509636911000|4, t: 3}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
