This posting is related to topic 1 : deleting a node from the farm. I found some more information but not the entire solution.
1) The edit real IP server configuration with column Server is not generated with the curl command but is visible in the GUI 2)The cgi script that generates the ' Real Server Table' is located in /usr/local/zenloadbalancer/www/content1-25.cgi If I can run the cgi script directly from curl that can generate the Real Server Table, I can extract the Server id.

I observed that adding a node to the farm is straight forward but when you want to delete a node from the farm, besides the ip address of the node you also need ?server id? . Is there a way in curl to get the server id by giving its ip address? For example node1 in the farm farm1 has the server id 0 since it was added first. node2 in the farm1 has server id 1 as it was added next. I can use curl to automate addition of nodes to the farm but to delete the nodes, in the url, i see the server id has to be mentioned. Is there a way through command line ( curl) i can extract the server id using the ip address of the node ? Your feed back is greatly appreciated.

HTML is intermittently not rending correctly on load-balanced web sites. The HTML renders correctly if I point a browser directly to each web server, but not if the HTML is served through the ZenLB. I have two test farms set up: iistest and Intranet. iistest is just the default website IIS website on port 80 on each server. Intranet is a vanilla, out of the box ASP.NET 4.0 website (generated by Visual Studio 2010), running on port 80 on a separate IP address on each server (10.0.2.161, 10.0.2.181,10.0.8.161). Intranet is an HTTP farm with a VIP of 10.0.2.201, with no persistence. Each web server has a copy of the same website, with the exception of adding text in the HTML of the server's name (so I could tell which web server is serving the data). Specifically, there seems to be an issue with widths and placement of divs, almost as though the CSS isn't being processed correctly. Again, pointing a browser directly to each web server works, and about 25% of the time, the HTML renders correctly through the LB. Any ideas? -Matthew D -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 3 Date: Mon, 4 Jun 2012 19:46:05 +0200 From: Emilio Campos <[email protected]> Subject: Re: [Zenloadbalancer-support] Problem rendering HTML on load balanced web servers To: [email protected] Message-ID: <cakwgn_punapqly8og+y6s+vve7mi8a4ip+gkwaugl5f22bu...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 One of your backends is not equal in web content that the others.

In fact, I had this problem when all three web servers pointed to the same files on our SAN. And if I put any two of the servers in the farm into maintenance mode, the page loads fine. If there is more than one active server in the farm, the HTML renders strangely about 75% of the time. Often, one of the servers will render incorrectly, but when I reload the page, it renders correctly. Which server it is doesn't seem to matter. IT also doesn't matter which server is active by itself. It always works if there is only one server. Similarly, it doesn't matter which combination of servers I have active simultaneously; if I have more than one server active in the farm, the HTML renders incorrectly about 75% of the time. Oh, and the farm is an HTTP farm. This really has me scratching my head...

I am guessing that somewhere there is a hard coded "eth0" .. Has anyone else tried this? I am using ZLB v2 and ifenslave-2.6 ..
