Hi,
I'm preparing to rollout 2.4.28 with n-way multimaster (in this case, it's really 2-way multimaster but could become more), and I'm looking to clarify what the exact canonical way to force a full refresh. Here's what I've come up with:
By "full refresh" I mean, blow away whatever is on machine Y with whatever's on machine X.
olcServerID: 1 ldaps://animal.clarku.edu olcServerID: 2 ldaps://zoot.clarku.edu
olcSyncrepl: {0}rid=001 provider=ldaps://animal.clarku.edu binddn="DN OF REPLICATION USER" bindmethod=simple credentials=<PASSWORD> searchbase="dc=clarku,dc=edu" type=refreshAndPersist retry="5 5 300 5" timeout=1 olcSyncrepl: {1}rid=002 provider=ldaps://zoot.clarku.edu binddn="DN OF REPLICATION USER " bindmethod=simple credentials=<PASSWORD> searchbase="dc=clarku,dc=edu" type=refreshAndPersist retry="5 5 300 5" timeout=1
1. Stop slapd on zoot.
2. slapcat > ocrap-backup.ldif
3. rm -rf /var/lib/ldap/* on zoot
4. SLAPD_OPTIONS="-c "rid=001,sid=001"" /etc/init.d/slapd start
Then wait and it will refresh.
Is this correct? Is there some easier way? Is there a way to do it without the rm -rf ? After it's done, do I need to restart slapd again without the -c option?
Thanks, and if I'm doing something stupid, I'm happy to look stupid in exchange for knowledge. :)

First, I would *strongly* advise you to download 2.4.29 plus the following patches, as they fix issues with Syncrepl, since I'm guessing you are not using delta-syncrepl based MMR.
By "full refresh" I mean, blow away whatever is on machine Y with whatever's on machine X.
olcServerID: 1 ldaps://animal.clarku.edu
olcServerID: 2 ldaps://zoot.clarku.edu

Stop slapd on zoot.slapcat > ocrap-backup.ldifrm –rf /var/lib/ldap/* on zootSLAPD_OPTIONS="-c \"rid=001,sid=001\"" /etc/init.d/slapdstart

You definitely have to do the rm -rf to remove the old DB. I would suggest, however, that you just slapcat the other master and load the data in to your the one you are updating, that will significantly reduce the time to sync.
