            <title>[SERVER-18430] SECONDARY can not catch up oplog in upgrade progess</title>
                <link>https://jira.mongodb.org/browse/SERVER-18430</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hi, I tried to upgrade my 2.4.11/12 mixed sharded cluster to 2.6.9, but failed as SECONDARY( hidden, priority=0 ) can not catch up oplog.&lt;/p&gt;

&lt;p&gt;CLUSTER STRUCTURE: &lt;br/&gt;
3 SHARDS, each mongodb instances listened on port 27018&lt;br/&gt;
3 configservers, each config server listened on port 27019&lt;br/&gt;
lots mongos deployed on app servers and listened on port 27020&lt;/p&gt;


&lt;p&gt;PREPAREDNESS:&lt;br/&gt;
As guide &lt;a href=&quot;http://docs.mongodb.org/manual/release-notes/2.6-upgrade/#preparedness&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/release-notes/2.6-upgrade/#preparedness&lt;/a&gt; said, we did some checks and found some problems descirbed on &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-17746&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-17746&lt;/a&gt; .&lt;br/&gt;
And we added args --setParameter failIndexKeyTooLong=false to avoid write failure , and ignored other errors .&lt;/p&gt;


&lt;p&gt;UPGRADE PROGESS:&lt;br/&gt;
As guide &lt;a href=&quot;http://docs.mongodb.org/manual/release-notes/2.6-upgrade/#upgrade-a-sharded-cluster-to-2-6&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/release-notes/2.6-upgrade/#upgrade-a-sharded-cluster-to-2-6&lt;/a&gt; said.&lt;br/&gt;
1, disabled write operations to metadata, done with no errors&lt;br/&gt;
2, disabled balancer, done with no errors&lt;br/&gt;
3, upgrade metad data, done with no errors&lt;br/&gt;
4, upgrade all mongos instanced to 2.6.9, done with no errors&lt;br/&gt;
5, stopped all 3 ARBITER role of each SHARD ( 3 in total ), as ARIBITER and mongoconfig running on the same box and intall mongodb-org-server(2.6.9) will remove package mongodb-10gen(2.4.x).&lt;br/&gt;
6, upgrade all 3 mongoconfig servers in &lt;font color=&quot;red&quot;&gt;reverse sequence&lt;/font&gt; of &lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;leaving the first system in the mongos --configdb argument to upgrade last.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt; done with no errors. &lt;br/&gt;
7, picked a  HIDDEN MEMBER of a SHARD, tried to upgrade  and failed as SECONARY can not catch up oplog.&lt;br/&gt;
!https://dn-snitch.qbox.me/FniYFGNRRbaKW_g9eW4UV9W5YMIn?&amp;amp;e=1431423576&amp;amp;token=bbdM74CLuWzsgblM-J_FvC6N06iZVRNR7StZcXKG:An8_3bLbPdbM7JekiNTl-IBkktw=) !&lt;br/&gt;

&lt;p&gt;I&apos;ve attached the full log and filter log of this member,  and mgcfg3.avoscloud.com(10.10.17.10) in the log is ARBITER.&lt;/p&gt;

&lt;p&gt;and mongodb-org-server:&lt;br/&gt;
db version v2.6.9&lt;br/&gt;
git version: df313bc75aa94d192330cb92756fc486ea604e64&lt;/p&gt;

&lt;p&gt;I don&apos;t know why this happen. May be it is a bug of 2.6.9?&lt;/p&gt;</description>

                            <comment id="939326" author="samk" created="Fri, 12 Jun 2015 19:16:20 +0000"  >&lt;p&gt;Thanks for this information. In 2.6, on startup &lt;tt&gt;mongod&lt;/tt&gt; must open each database while starting up to clean up aborted index builds. Just to be clear, the string &quot;IndexRebuilder&quot; refers to the name of the thread doing this work and not to the action its performing. I&apos;m going to go ahead and close this ticket, as the SERVER project is for bugs with MongoDB itself, and questions about performance and operations are probably better addressed to one of our &lt;a href=&quot;http://www.mongodb.org/about/support&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;support channels&lt;/a&gt;. &lt;/p&gt;

&lt;p&gt;Regards, &lt;br/&gt;

1. start up to listen on port,  2.4: 22 minutes, 2.6.10: 20 minutes. &lt;br/&gt;
 IndexRebuilder time,  2.4: none, 2.6.10: 13 minutes&lt;br/&gt;
become into SECONDARY, 2.4: 0 second, 2.6.10: 34 minutes&lt;br/&gt;
and in total, 2.4 is 22 minutes and 2.6.10 is 67 minutes&lt;br/&gt;
2, Yes&lt;br/&gt;
3, Yes&lt;br/&gt;
4, There are 10930 databases( and approximately more than 70,000 collections with indexes, and nearly 90% collections may not have store any records ).&lt;br/&gt;
 There are 33053 files in dbPath.&lt;br/&gt;
5, SSD and 15k SAS disk,  and start up time of SSD is half of 15k SAS disks.&lt;/p&gt;

&lt;p&gt;IndexRebuild progress cost much time, even we have set --noIndexBuildRetry, and the count number of keyword &lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;[IndexRebuilder] opening db: ...&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;in start up log  is almost equal to database counts. I can not tell is it rebuilding index or just checking index from log.&lt;/p&gt;

&lt;p&gt;Thank you. &lt;/p&gt;</comment>
                            <comment id="935547" author="samk" created="Tue, 9 Jun 2015 19:30:47 +0000"  >&lt;p&gt;I&apos;m glad to hear that you&apos;ve successfully upgraded now. I just want to ask a few questions about your deployment to better understand the difference in start up time?&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;In absolute time how long does it take for a &lt;tt&gt;mongod&lt;/tt&gt; to start up with 2.6.10 versus 2.4?&lt;/li&gt;
	&lt;li&gt;Is the start up time consistent across all members of the set?&lt;/li&gt;
	&lt;li&gt;Are start up times consistent between restarts?&lt;/li&gt;
	&lt;li&gt;Exactly how many databases does your data set have? How many files are in your &lt;tt&gt;dbPath&lt;/tt&gt;?&lt;/li&gt;
	&lt;li&gt;What kind of underlying storage system are you using (SSD? local storage, network storage?)&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Thanks, &lt;br/&gt;

&lt;ul&gt;
	&lt;li&gt;Networking is good. Lots of connections to arbiter role(10.10.17.10) refused as arbiter was stopped at that time.&lt;/li&gt;
	&lt;li&gt;Yes, the ARBITER role was stopped at that time.&lt;/li&gt;
	&lt;li&gt;Maybe, I&apos;m not sure if there have any index build in progress before the upgrade. And Yes, My instance&apos;s workload include a large number of database and collection creation options( include indexes) . But at that period of upgrade, applications had not create any databases or collections, I&apos;m sure of that as we deployed applications without the ability to change metadata before upgrade. Or maybe there are mistake/problem with indexes?&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;We upgraded our production mongo cluster to 2.6.10 a few days ago. Everything looks ok, except the startup time of mongod instance is about triple than 2.4. &lt;/p&gt;</comment>

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;The logs contain a large number of interprocess &lt;tt&gt;mongod&lt;/tt&gt; connection errors.  Have any networking connections changed?&lt;/li&gt;
	&lt;li&gt;From your notes it doesn&apos;t look like you restarted the arbiter after upgrading the instance. Is this correct? Was the arbiter available and a member of the set when you were attempting to upgrade the shard? If the arbiters are not running when you attempt to upgrade the hidden member, could to attempt the upgrade with them running?&lt;/li&gt;
	&lt;li&gt;It appears as if the members of the replica set are attempting to build indexes based on the log? Was an index build in progress before the upgrade? Does your instance&apos;s workload include a large number of database and collection creation options,&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;If you could provide answers to these questions it will help us understand what&apos;s going on here.&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;

   We have copied one SHARD&apos;s data and tested the upgrade procedure, and succeed. Upgrade process take too much ( 3x ) time than just running up.&lt;br/&gt;
   We will upgrade our production cluster later.&lt;br/&gt;
   Thank you, guys.&lt;/p&gt;</comment>

&lt;p&gt;finally, the upgrade process was canceled. And mgsh43 downgrade to 2.4.14, this member can catch up with other members.&lt;/p&gt;
