True.  I assumed the original poster was asking about scalability issues.

Without having run cyrus in a cluster configuration, it is my belief
that common clustering technology could be used without a problem.
Note that in such a case you're commonly not actually using a distributed
filesystem, but rather shared disk for the mail spool, the mail store,
the extra cyrus database files, and related stuff.  Beware of cheap
cluster solutions that are susceptible to split-brain syndrom.

You could, of course, make your world even more complicated by
running a set of clustered mail stores behind a murder aggregator,
thus addressing both scalability and redundancy ...
