Dear List , I am testing on Openldap-2.4.7 multi-master replication , and I had been read Openldap Admin page for a while already ( URL : http://www.openldap.org/doc/admin24/replication.html#delta-syncrepl%20replication ) Now I get confuse on " N-Ray Multi-Master " & " Mirror Mode Multi-Master " Hope somebody else could help. Testing enviorment: I got 3 office. Office A / Office B & Office C. Each office I got 2 x LDAP Server ( Totally 6 Openldap 2.4.7 ) Office A Openldap Server 1 = Server A1 Office A Openldap Server 2 = Server A2 Office B Openldap Server 1 = Server B1 Office B Openldap Server 2 = Server B2 Office C Openldap Server 1 = Server C1 Office C Openldap Server 2 = Server C2 The things I want : Each node could " Read & Write " on it's own database and replication the other 5 left Openldap Server. Question : I suppose to be use N-Ray Multi-Master OR Mirror Mode Multi-master ? Question about N-Ray Multi-Master. ( Assume I have 6 physical Openldap 2.4.7 * Fresh Install * ) 1. If I am looking to setup N-Ray Multi-Master , is that I need to make all 6 node as Provide And Consumer on each openldap servers slapd.conf ? 2. For consumer config in slapd.conf * assume i do a simple concumer config in Server A1 ) , is that I need point all the providers servers infomration in ServerA1 slapd.conf ? 3. IF Office A / Office & Office C VPN network is down and get resume after 10 mins, what's the recover procedure that I could make sure that all server by using same version of " Database" and each node database is consistence ? Question about Mirror Mode mode Multi-Master. 1. Is that Multi-Master Mirror Mode only could support more than 2 x Openldap servers which's by usning Multi-Master Replication ? 2. Refer Question 1. Is that Multi-Master only allow to WRITE on 1 of 2 servers at the same time? 3. Is that possible make all 6 x Openldap Servers running as N-Ray + Mirror Mode Mode Multi-Master ( IF Mirror mode could support more than 2 x openldap-servers ) At last just want to understand that is there anyway make each node as multi-master and able to read / write it's own database & replication together. 4. IF Office A / Office & Office C VPN network is down and get resume after 10 mins, what's the recover procedure that I could make sure that all server by using same version of " Database" and each node database is consistence ?
