                            <comment id="4379694" author="louis.williams" created="Mon, 28 Feb 2022 09:14:54 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=milkie&quot; class=&quot;user-hover&quot; rel=&quot;milkie&quot;&gt;milkie&lt;/a&gt;, I think even if we set the mode to RECOVERING, the node will stop replicating and have the same observed availability problems unless we also eliminate the PBWM lock.&lt;/p&gt;

&lt;p&gt;I also think that separately, serverStatus should opt-out of the PBWM lock, since this is important to observability.&lt;/p&gt;</comment>
                            <comment id="4376700" author="milkie" created="Fri, 25 Feb 2022 13:35:09 +0000"  >&lt;p&gt;I wonder if we should revert back to setting RECOVERING state automatically during compact, so that users don&apos;t need to worry about one secondary being not entirely usable.  The easiest way for a user to avoid sending read requests to a not entirely usable node is indeed to simply set maintenance mode.&lt;/p&gt;</comment>
                            <comment id="4376512" author="louis.williams" created="Fri, 25 Feb 2022 10:58:58 +0000"  >&lt;p&gt;If compact doesn&apos;t take the PBWM lock, which I don&apos;t believe it should, then we don&apos;t need to make it yield. We just need to make it clear in our documentation that the node in question is &quot;available&quot;, but will be under extra load that may not make it entirely usable.&lt;/p&gt;</comment>
                            <comment id="4376339" author="josef.ahmad" created="Fri, 25 Feb 2022 08:11:48 +0000"  >&lt;p&gt;It would be also useful to determine if we can make compact yield periodically, to avoid the contention with other acquirers with stronger mode.&lt;/p&gt;</comment>
