I.e., it's primary > DB remains empty. Ah, that wasn't mentioned, my assumption was that the source DB was actually empty. This is coming from ITS#8281 fix in cd8ff37629012c1676ef79de164a159da9b2ae89. There are two scenarios that need different treatment: 1. We start with no servers and no data and want to set up MMR from there 2. We start with a live server and want to move over to MMR The bootstrap scenario is the one I outlined in my response above, the consumers should be able to deal with it correctly if they do what I say. However the provider should make it possible for the client to know that's what's happening, so it should only send an empty cookie-less response in the case DB is empty. The conversion to MMR should be dealt with differently. AFAIK, the correct order of set up is: - prepare original master: - serverID == 0 - add syncprov - change serverID accordingly - connect other servers: - set serverIDs - add olcSyncrepl everywhere (including original master) - wait for things to settle, you're done I agree it is necessary we make sure not following the above still results either with a helpful error or that it also Just Works(tm).

(ITS#9016) cn=config should fail on EMIT if target directory not empty
by ondra＠openldap.org 24 Apr '19

24 Apr '19

Full_Name: Ondrej Kuznik Version: re24/master OS: URL: Submission from: (NULL) (82.10.24.68) Running slapd/slaptest to convert a slapd.conf to cn=config will happily reuse the target directory. However if there was some existing configuration present already, slaptest reports a successful conversion, even though the resulting directory most likely won't represent the slapd.conf used - existing .ldif files won't be replaced or removed. Depending on the differences between slapd.conf and slapd.d in place, the result might not even be a useable cn=config anymore. Since it's not feasible to clean up properly, it should just return an error instead?

The consumer did not replicate the database as a part of the initial=20 search, so I don't think it qualifies as "up to date". I.e., it's primary=20 DB remains empty. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Ok, I think this is consumer's fault and limited to refreshAndPersist deltasync (with or without MMR). Going by what I think I remember of the consumer code did: - on set up, it finds out there's no cookie to go by so it goes into refresh on the main DB - main DB responds with success but no/empty cookie - consumer starts over but again finds itself with no cookie, so it goes to step one But the consumer is actually up to date at that point as the search suggested, so it should just go ahead and do the refreshAndPersist on accesslog as it planned to originally. And as operations hit the main DB, they will replicate accordingly, even if that were to happen after the original search and before this one[0]. So in that case the behaviour would be as follows: - on set up, it finds out there's no cookie to go by so it goes into refresh on the main DB - main DB responds with success but no/empty cookie - consumer starts over, remembering that its cookie (albeit empty) is valid, so sends a refreshAndPersist search on accesslog DB - that yields no traffic, but will give it the right data once anything replication-worthy happens, job done - unless the connection is actually severed (restarts, ...) before anything needs replicating, we start from step one but no overhead was incurred, we're still fine [0]. Unless so much time has elapsed between the two searches (that happen on the same connection BTW) that some accesslog ops have already been expired. Expiration is usually configured in days, not seconds and an admin that doesn't notice a consumer going AWOL for that amount of time probably deserves that. -- Ondřej Kuzník Senior Software Engineer Symas Corporation http://www.symas.com Packaged, certified, and supported LDAP solutions powered by OpenLDAP

Since the consumer never disconnects, there is no reconnect. It connects a single time, and issues the same operation endlessly. Thus why when you look at the log file snippet I pasted, you see an OPERATION count in the MILLIONS. conn=1003 op=361869515 I.e., OPERATION 361,869,515 for connection 1003. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
