I would be grateful.

Glusterfs is there to avoid SPOF - as the filesystem sits on two 
servers. So assuming I won't do rm -rf /gluster-filesystem, it should be 
quite safe. And it too needs twice the disk space, since it's replicated 
with glusterfs on both servers.

However, I'm of course open to better alternatives.

I'm running Debian Lenny, which ships with Cyrus 2.2.13 - not sure if 
Cyrus replication is possible there? I'd like to stick with distro 
packages, but if a newer Cyrus version provides features which let you 
do HA without too much hackarounds, I'll consider upgrading.
