Re: Replication error after initializing consumer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Once the init is done, the following is repeated on the consumer (when logging is turned up).  Note that the ADD was done while the init was happening and after the init is done, the entry does exist on the consumer but, from what I can tell, the supplier wants to still send it to the consumer and the consumer is rejecting it.

Also, the other issue that I'm noticing is that a couple of my consumers seem to be crashing (about once a day).  Right now, they are not getting any traffic at all other than updates from replication.  I'm debugging that at the moment and will report what I find.

Subject: Re: Replication error after initializing consumer

Hello,

This logs are coming from the supplier. It confirms what you said. The supplier retrieves a starting point for sending updates (53f5e4b5000000050000) then sends the next update 53f5e647000000050000 (uid=shilen3,ou=people,ou=test,dc=duke,dc=edu). For some reason the consumerhost:636 is unwilling to apply the update (is the backend readonly ?).
Have you got the error logs from consumerhost (with replication logging enabled) ?.

thanks
theirry

Hi Mark,

So with this issue, I'm not adding a password at all to the entry.  See the LDIF in (2) below.
No, I was referring to your first email, not this issue.  Sorry I should of responded separately. 
 I'll open a ticket.
For what issue?  For the initialization issue I want you to grab the logging first.  For the first issue(userpassword not being replicated), if you can reproduce it when only adding already hashed passwords, then please file a ticket with a reproducible testcase. 

I hope that clears things up.

Regards,
Mark

Shilen,

A few things, you should not be adding a prehashed password (e.g.  {SSHA}DMK4S6PK6+rKSLNOL1Hl01mVJmgGi5jH) - but that should not break replication.  Can you confirm that only prehashed passwords are causing the issue?  If so, please files a ticket with a reproducible testcase:  https://fedorahosted.org/389/newticket

As for this replication issue, enabling replication logging might provide more information:

https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Configuration_Command_and_File_Reference/error-logs.html#error-logs-levels

Then post the logging output back on this list.  You should also undo this logging level once you're done - as this logging level can impact performance.

Thanks,
Mark

Hi,

I'm not sure if this is related to my previous email, but I'm also seeing issues when adding an entry while a suffix on a consumer is being initialized.  Again, I'm running 1.2.11.30.  Here are the details:

1.  Using the console, I started to initialize a suffix.

[19/Aug/2014:17:46:35 +0100] NSMMReplicationPlugin - Beginning total update of replica "agmt="cn=test5toSing1" (consumerhost:636)".

2.  While that was happening, I added an entry to the suffix on the master.

dn: uid=shilen3,ou=people,ou=test,dc=duke,dc=edu
changetype: add
objectclass: top
objectclass: person
objectclass: inetorgperson
objectclass: organizationalperson
cn: test
sn: test
uid: shilen3

3.  The init later finished.

[19/Aug/2014:17:48:55 +0100] NSMMReplicationPlugin - Finished total update of replica "agmt="cn=test5toSing1" (consumerhost:636)". Sent 270 entries.

At this point, the entry does exist on the consumer.  Presumably it was added as part of the init.


4.  However, the master still wants to send the ADD to the consumer.  On the consumer, I have the following repeated every few seconds:

[19/Aug/2014:17:48:54 +0100] conn=2002 op=56 ADD dn="uid=shilen3,ou=people,ou=test,dc=duke,dc=edu"

And on the master, I have this:

[19/Aug/2014:17:48:58 +0100] NSMMReplicationPlugin - agmt="cn=test5toSing1" (consumerhost:636): Consumer failed to replay change (uniqueid 5d458a02-27c011e4-a066d327-58be45f0, CSN 53f37f89000000050000): Server is unwilling to perform (53). Will retry later.
