            <title>[DOCS-15737] [Server] Investigate changes in SERVER-68852: Investigate handling of incorrect values for balancer settings</title>
                <link>https://jira.mongodb.org/browse/DOCS-15737</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    Added json validator to config.settings collection. Now, updates/inserts on config.settings with _id: &quot;chunksize&quot; will be rejected if the value is invalid. And any updates/inserts where the _id is an unexpected value will be rejected.&lt;br/&gt;
All existing incorrect values will be left as is.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    While investigating uses of NaN in the balancer, it came up that if the user updates the maxChunkSize to a value not accepted by the balancer (NaN, -10, etc.), the balancer and all other operations that rely on the balancer configuration setting will fail until the setting is changed. These operations are:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;all balancer operations&lt;/li&gt;
	&lt;li&gt;add shard&lt;/li&gt;
	&lt;li&gt;chunk autosplitting and initial chunk splitting&lt;/li&gt;
	&lt;li&gt;manual migrations&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;This ticket is to investigate whether this is a problem and if there is a way to reject the write of an invalid value rather than checking it at runtime.&lt;/p&gt;
