Hi Everyone:
I would like to setup active/passive clustered servers that are
connected to a data array. Has anyone done this? Does anyone have
instructions for doing so with qmail toaster?
Thanks,
There have been several users that have done some of this - I've build
clusters where several machines accept email and allow POP/webmail
clients (using a backend machine as a mysql/NFS server). A lot of
others have built machines using heartbeat as well, so if the machine
fails the backup will take over. Depends on your needs. If it's
redundancy, then heartbeat is the easiest. If you need raw power, the
cluster is good for 1M or more messages a day (this really only
benefits ISPs).
I'm not needing the 1M power just looking for redundancy and actually
had heartbeat in mind. Is there some place I can get instruction for
setting up qmail in this manner?
Thanks.
Ed,
I'm presently beginning a venture down this road too (for a client). The
documentation at the Linux-HA (heartbeat) web site (http://www.linux-ha.org)
is a bit sketchy. I'm hoping that the documentation that comes with the
package is a little better.
Don't forget the user list,
http://lists.linux-ha.org/mailman/listinfo/linux-ha
(I had a hard time finding it).
