Replacing a DS server
We are replacing one of our two 389 servers. I want to re-use the IP address of the old server on the new one. What’s the correct order of events for replication, shutdown and replacement?

Replacing a DS server
HiIts difficult to say wiithout knowing how you have configured your two servers...
In setups that I have had previosly I just rebuild the server (OS) and install 389.before I continue I remove the "old" server from the config database as that was multimastered as well. I then continue the 389 registration by running setup-ds.plI have lost my exact steps that I have followed but basically if you have a multimaster environment the new server will just be viewed as a very out of date master and for a while will be busy. You can populate it from the gui which will repopulate the database.* Regards On 8 March 2012 15:14, <mjames@guesswho.com> wrote: We are replacing one of our two 389 servers.

Replacing a DS server
@Gerhardus - Thanks for your help. I inherited the setup. 2 servers with multi-master replication on RH 5.6 / 5.7. The new replacement server will be CentOS 6.2. Version info follows.
* The “old” RH servers: [root@x-389-01 src]# ns-slapd -v 389 Project 389-Directory/1.2.2 B2009.237.2042 * [root@x-389-02 ~]# ns-slapd -v 389 Project 389-Directory/1.2.2 B2009.237.2042 * The CentOS server: [root@x-389-01_v ~]# ns-slapd -v 389 Project 389-Directory/1.2.10.3 B2012.065.2318 * Mike * * From: 389-users-bounces@lists.fedoraproject.org [mailto:389-users-bounces@lists.fedoraproject.org] On Behalf Of Gerhardus Geldenhuis Sent: Thursday, March 08, 2012 10:23 AM To: General discussion list for the 389 Directory server project.

Not sure I was much help. I am sure Rich will jump into the conversation. I am proper back at work next week and can then dig around and give you a more complete answer with regards to exact steps if you can wait that long.
