            <title>[SERVER-57612] Investigate whether we can perform a fake disk write in a dry-run election</title>
                <link>https://jira.mongodb.org/browse/SERVER-57612</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;During an election, if disk operations are failing on a voting node, the real election can never succeed because &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r4.4.6/src/mongo/db/repl/replication_coordinator_impl.cpp#L4941&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;we attempt&lt;/a&gt;&#160;to store the last vote document on disk. However, we don&apos;t perform a disk operation during dry-run elections, so they can still succeed. We can get into a state where a node is repeatedly voting &apos;yes&apos; in the dry-run election, but timing out (due to the disk operation) in the real election. This can cause the term to escalate quickly to a very high number.&#160;&lt;/p&gt;

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

&lt;p&gt;As suggested, we should try to investigate and see if we can perform a &apos;fake&apos; disk write in the dry-run election, to ensure that if disk operations are failing, we fail the dry-run election.&lt;/p&gt;</description>
