Rich,

I was thinking about the "Replica has a different generation ID than the local 
data." error, because I have seen this before. If possible, I want to avoid 
that I have to go though each box and re-initialize.

So, you suggest I take let's say D (or A) and re-initialize B with D's data. 
Then, I would have to re-initialize F from B, right?

Let's go a bit further: If I had an agreement from A to F (and vice versa), I 
would not even have to re-initialize F from B. Is this correct?

-Reinhard

How do I do this manually on server A?

The other question is, what kind of impact does it have when I re-iitialize 
server B? To be more precise, my replication environment is more complex than 
just server A and server B. In fact, I have a setup like the following:

srv C <--> srv A <--> srv B <--> srv D <--> srv C
                 /\             /\
                 |               |
                \/              \/
              srv E          srv F

I don't want to end up to re-initialize all boxes in my environment.
Assuming C and D are up to date and don't have any problems, reinitializing B 
should affect only B and F.

Thanks,
-Reinhard

Hi,

I encountered the following logs in the errors:

[06/Oct/2011:10:11:57 +0000] NSMMReplicationPlugin - changelog program - 
agmt="cn=srvAtosrvB" (srvB:389): CSN 4e8d804a0000000c0000 not found, we aren't

(srvB:389): Data required to update replica has been purged. The replica must 
be reinitialized.


[06/Oct/2011:10:11:57 +0000] NSMMReplicationPlugin - agmt="cn=srvAtosrvB" 
(srvB:389): Incremental update failed and requires administrator action



Does anyone have an idea, what could have caused this and more importantly, how 
to fix this?



Thanks

On server A, read a changelog to manually run the changes on server B.
May be tune up nsds5ReplicaPurgeDelay if such errors somehow appears regularly.
Otherwise, like the errors log says, the change was purged/removed, and replica 
need a re-init.
