Hi there,
we are working on building a redundant cluster as
webserver. In other words we have 2 machines that will serve pages to the web
and if one crashes the other takes over. These machines also will be doing load
balancing so they'll both be responcible for 50% for the hits on the webpages,
mail etc. They both have a partition that is an exact copy of the other machine,
we do this by running intermezzo, a new tool that catches kernel calls and dupes
them to the other configured machines. We've called this partition
/bigdisk.
Anyways to get to the point, we also want to run
majordomo on both this machines, but I was wondering if this is gonna cause any
troubles with the mailing lists and/or digests. The mailinglists will be on the
/bigdisk partition so both copies of majordomo will access the same lists. Since
for the mailinglists the server that recieves mail starts majordomo and sends I
don't think this will cause any problems, but I'm wondering what will happen
with the digests? As I understand they will be send out at a particular time or
when the file is full or when there are enough messages in it... Since this will
be the same for both machines I am afraid both machines will send the digest and
people will get the mail twice then?
Any suggestions/ideas to solve this would be
greatly appreciated.
Kind regards,
Ferry van Steen
