Hi List, I have cfg LDAP multimaster replication, one of the hosts will be offline for some days, do I need to disable the replication agreement completely at this point? (what will be the minimum cfg) What are the steps to resync the master after is been brought online ? Thank you Isabella

I think that removing the replication agreement is the best course of action.

Say you have A <-> B, and you plan to disable B.

You would disable the replication agreement of B -> A first, then A -> B

Then when you reactivate B, you would add the replication agreement for A -> B, with the attribute nsds5beginreplicarefresh: start

Then once complete, you would re-add B -> A.

you can avoid the reinitialization if you ensure that the changelog is not purged too much, if the server is down for "somedays" set nsds5replicapurgedelay: somedays+1, when the other server is coming online replication should catch up (disabling and reenabling should be enough)

Sincerely,
