Hi all, I am using openldap 2.4.11, and configure as 4-way Master, config files for server A,B,C,D are shown below : Server A : syncrepl rid=A provider=ldap://serverA:389/ retry="1 +" ...... syncrepl rid=B provider=ldap://serverB:389/ retry="1 +" ...... syncrepl rid=C provider=ldap://serverC:389/ retry="1 +" ...... syncrepl rid=D provider=ldap://serverD:389/ retry="1 +" ...... serverID 001 Server B : syncrepl rid=A provider=ldap://serverA:389/ retry="1 +" ...... syncrepl rid=B provider=ldap://serverB:389/ retry="1 +" ...... syncrepl rid=C provider=ldap://serverC:389/ retry="1 +" ...... syncrepl rid=D provider=ldap://serverD:389/ retry="1 +" ...... serverID 002 Server C : syncrepl rid=A provider=ldap://serverA:389/ retry="1 +" ...... syncrepl rid=B provider=ldap://serverB:389/ retry="1 +" ...... syncrepl rid=C provider=ldap://serverC:389/ retry="1 +" ...... syncrepl rid=D provider=ldap://serverD:389/ retry="1 +" ...... serverID 003 Server D : syncrepl rid=A provider=ldap://serverA:389/ retry="1 +" ...... syncrepl rid=B provider=ldap://serverB:389/ retry="1 +" ...... syncrepl rid=C provider=ldap://serverC:389/ retry="1 +" ...... syncrepl rid=D provider=ldap://serverD:389/ retry="1 +" ...... serverID 004 I find a strange behaviour, data can be synced within all 4 servers, however, after some time, I find that when I add/update data in server A, it can sync to server B immediately, server C and server D can't receive the updated data., I check the log in server C and server D, there is no data push to C and D. (I set the log level 16384 to log the sync) When I add record in server C, data can be sync to server D immediately, server A and server B can't receive the updated data. But after some time (may be 1-2 hours), the data between the 4 servers are synced finally. Another information is that server A and B are in same segment, server C and server D are in same segment, but server A and C/D are in different segment. The ping test between servers are fast. I also use telnet server A/B/C/D 389, the response is fast. Any idea ? Thanks 5 GB 超大容量 、創新便捷、安全防護垃圾郵件和病毒 — 立即升級 Windows Live Hotmail? |
