Hi all,
Hi
I'm trying to setup a Mirror Mode configuration using 2 machines running OpenLDAP v2.4.11 on both. To make things easy both machines are on the same (private) network.
[snip] mirrormode on
I'm using Ubuntu 8.10 inside a VMWare image, but both images are running on independent machines and the network on both is Bridge Mode.
From previous experiment, especially with OpenLDAP 2.4.11, I have very hard
time with making OpenLDAP N-way replication working on VM, especially VMWare-based ones.
The main problem was with the management of the system clock, where VMWare was making the clock slower and then make a "jump" to compensate the slowiness. So, I got a lot of line "new modification with older timer value" (can't remember the precise log line, though).
I had to switch to plain physical server (which was my target by then).
All seems well according to OpenLDAP manual, but maybe I'm missing something. I start both servers using "slapd -d sync" in order to filter only the sync part.
I created a script to insert 200 employees in my directory, to force the servers to sync up. When I start both servers and insert the employees in machine 1, I get this too much lines with this sample: slap_queue_csn: queing 0xb6851b4a
20090623082909.571025Z#000000#000#000000
slap_graduate_commit_csn: removing 0xb82165c8 20090623082909.571025Z#000000#000#000000
So the CSN is being created (I think), but there's no sync to machine 2, which makes me frustated. . .
I'd appreciate any comments you can have, especially if you already have this kind of setup running.
Best regards, Fernando
Hope it can help. Sincerely yours, Mathieu MILLET.
