Hi John,

-----Original Message----- From: mailman-users-bounces+ifetch=du.edu@python.org [mailto:mailman-users-bounces+ifetch=du.edu@python.org] On Behalf Of John Wingenbach Sent: Tuesday, November 09, 2010 11:55 AM To: mailman-users@python.org Subject: [Mailman-Users] Redundant Mailman servers

Hi,

I am trying to set up redundant/parallel mailman servers. In order to accomplish this, I will have 3 servers which run mailman on them. One server at a time will be determined to be the "admin" point. However, all three will enable distributing email to the pertinent lists.
Obviously, archival of the mail to the lists is not enabled or supported.

ADMINSERVER -> points to one of SERVERA, SERVERB or SERVERC Email to the lists gets sent to any of SERVERA, SERVERB or SERVERC (MX distributes to all 3 servers). Configurations from ADMINSERVER are to be sync'd to the other 2 servers.

The problem I am running into is that when I duplicate the lists to the other servers, the lists which are "advertised" on the current admin server do not show up as advertised. However, config_list shows the lists as advertised. I am duplicating the following files across the servers:

/var/lib/mailman/data/aliases /var/lib/mailman/lists/*

What am I missing such that /mailman/admin will display the same set of advertised lists?

Thanks, John

I wonder if this could be the host_name option for the mailing lists, vs. DEFAULT_EMAIL_HOST and DEFAULT_URL_HOST on your two other Mailman servers? In other words, a difference between the Mailman configured email and web server hostnames, among your 3 servers.

See the FAQ at <http://wiki.list.org/x/lYA9>.

Because each of your servers has a different web host name, only one server's name will match the host name in the list's web_page_url attribute and only that server will display the lists.

The easiest fix is to set

VIRTUAL_HOST_OVERVIEW = Off

in mm_cfg.py. Then the host names don't need to match. The more elaborate fix is to make sure that each hosts DEFAULT_URL_HOST is set appropriately in it's mm_cfg.py and run fix_url after copying lists/*/config.pck.
