            <title>[SERVER-83433] Add back the test coverage for running db hash check on replica set that is fsync locked and has replica set endpoint enabled </title>
                <link>https://jira.mongodb.org/browse/SERVER-83433</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The db hash check for a ReplSetTest involves running &lt;a href=&quot;https://github.com/10gen/mongo/blob/9f49101645a5d21784a89df563f81ae83e9017ed/src/mongo/shell/data_consistency_checker.js#L593-L595&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;collStats commands&lt;/a&gt; against each mongod while it is fsync locked. On a mongod with replica set endpoint enabled, those collStats commands are handled using the router code paths which may &lt;a href=&quot;https://github.com/10gen/mongo/blob/d1e66593694206bbf4d12ddae309e99d0feb9010/src/mongo/s/commands/cluster_coll_stats_cmd.cpp#L245-L246&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;trigger a catatlog cache refresh&lt;/a&gt;. The router service on mongod currently uses the ShardServerCatalogCacheLoader (&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-82588&quot; title=&quot;Move CatalogCacheLoader to be a decoration on Service&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-82588&quot;&gt;&lt;del&gt;SERVER-82588&lt;/del&gt;&lt;/a&gt;). So when a refresh occurs, it requires doing a &lt;a href=&quot;https://github.com/10gen/mongo/blob/3f75c7bc452cb0b63923c5521e1c7666edd406cf/src/mongo/db/s/shard_server_catalog_cache_loader.cpp#L1030-L1032&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;noop write&lt;/a&gt; which will then deadlock since the mongod is fsync locked. This deadlock should go away after &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-82588&quot; title=&quot;Move CatalogCacheLoader to be a decoration on Service&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-82588&quot;&gt;&lt;del&gt;SERVER-82588&lt;/del&gt;&lt;/a&gt;. For now, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-81968&quot; title=&quot;Make mongod dispatch commands through router code paths if applicable&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-81968&quot;&gt;&lt;del&gt;SERVER-81968&lt;/del&gt;&lt;/a&gt; has temporarily changed the number of nodes in the replica sets in the rs_endpoint/ tests with user collections to 1 to avoid the db hash check.&#160;&lt;/p&gt;</description>
