            <title>[SERVER-73383] Defragmentation may start over right after finishing</title>
                <link>https://jira.mongodb.org/browse/SERVER-73383</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;It may happen that defragmentation start over right after finishing.&lt;/p&gt;

&lt;p&gt;This is the flow that leads to a defragmentation undesired restart on collA:&lt;/p&gt;

&lt;p&gt;1. The &lt;tt&gt;Balancer&lt;/tt&gt; thread &lt;a href=&quot;https://github.com/10gen/mongo/blob/a90fbff8489b1ecd9872f63136ea1bd938ca1361/src/mongo/db/s/balancer/balancer.cpp#L775&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;reads all the collection entries&lt;/a&gt; when &lt;tt&gt;collA&lt;/tt&gt; defragmentation didn&apos;t finish yet.&lt;/p&gt;

&lt;p&gt;2. Defragmentation on &lt;tt&gt;collA&lt;/tt&gt; finishes and the &lt;tt&gt;BalancerSecondary&lt;/tt&gt; thread &lt;a href=&quot;https://github.com/10gen/mongo/blob/512897c5d6f9047b340d3b1305477811d3ac3c59/src/mongo/db/s/balancer/balancer_defragmentation_policy_impl.cpp#L1360&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;removes the _defragmentationStates collection entry&lt;/a&gt; and &lt;a href=&quot;https://github.com/10gen/mongo/blob/daa6fb3e8fdae969996e211a2e83e1b35ef80992/src/mongo/db/s/balancer/balancer_defragmentation_policy_impl.cpp#L1754-L1784&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;clears the defragmentation flags&lt;/a&gt; on &lt;tt&gt;collA&lt;/tt&gt; config.collections entry&lt;/p&gt;

&lt;p&gt;3. The &lt;tt&gt;Balancer&lt;/tt&gt; calls &lt;a href=&quot;https://github.com/10gen/mongo/blob/a90fbff8489b1ecd9872f63136ea1bd938ca1361/src/mongo/db/s/balancer/balancer.cpp#L777&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;startCollectionDefragmentation&lt;/a&gt; using a stale &lt;tt&gt;config.collections&lt;/tt&gt; entry for &lt;tt&gt;collA&lt;/tt&gt; and an updated &lt;tt&gt;_defragmentationStates&lt;/tt&gt; map&lt;/p&gt;

&lt;p&gt;4. Due to point 3, on &lt;tt&gt;startCollectionDefragmentation&lt;/tt&gt; function, we don&apos;t return on &lt;a href=&quot;https://github.com/10gen/mongo/blob/daa6fb3e8fdae969996e211a2e83e1b35ef80992/src/mongo/db/s/balancer/balancer_defragmentation_policy_impl.cpp#L1440-L1442&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this&lt;/a&gt; condition and we &lt;a href=&quot;https://github.com/10gen/mongo/blob/daa6fb3e8fdae969996e211a2e83e1b35ef80992/src/mongo/db/s/balancer/balancer_defragmentation_policy_impl.cpp#L1443&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;init the collection defragmentation&lt;/a&gt; again.&#160;&lt;/p&gt;

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

&lt;p&gt;Note that when defragmentation starts over unexpectedly, the &lt;tt&gt;defragmentCollection&lt;/tt&gt; field for &lt;tt&gt;collA&lt;/tt&gt; remains unset, while the &lt;tt&gt;defragmentationPhase&lt;/tt&gt; field has a valid defragmentation phase other than &lt;tt&gt;null&lt;/tt&gt;.&lt;/p&gt;</description>
