I have always suspected that this is due to the specific setting of:
syncprov-checkpoint <ops> <minutes> After a write operation has succeeded, write the contextCSNto the underlying database if <ops> write operations or more than <minutes> time have passed since the
last checkpoint. Checkpointing is disabled by default.
Not sure though.
Hi,
do you "query" by slapcat or by an LDAP search? For the former it's documented that contextCSN is updated lazily. For the latter I'm not sure.
I have had the same use case Michael is getting at in the back of me head for some time. I would also like to verify replication status by checking the contextCSN on all servers via an ldapsearch from a monitoring script.
I would expect an ldapsearch of the contextCSN to deliver a current and valid value that should be identical over all servers.
It seems this is not the case. I will run a couple of tests to verify this myself in my testbed of 2 mmr masters and 2 slaves.
Greetings Christian
