Good afternoon.
There is a situation: mail and DNS servers running on a Debian machine.
I would like to somehow increase the fault tolerance of the server, so the idea arose to create a cluster from this machine, and one more.
Tell me, what are the options for creating a cluster of debian servers?

I almost never worked with Debian, but in this case I would look towards Heartbeat for a detailed article on setting up www.opennet.ru/base/sys/ha_cluster_setup.txt.html , it is possible to use peacemaker, but heartbeat is easier to configure and is quite sufficient for this task . There were several articles on peacemaker on Habré.

if you already want a cluster, then somewhere in the direction of systemimager, for example. according to past works, this tool in thick scripting was used together with svn

Mail and DNS are "clustered" by protocol specs. It makes no sense to bother with OS clustering in this place.

Well, why such difficulties ... It's time to virtualize and provide a cluster at the hypervisor level.

Put Xen and your servers on top of it
. A simple accessibility script is enough to drag the service to another host in the domain.
