The goal: a resilient and geographically distributed mailstore. A mail server is a very dynamic thing, with files being written, moved and deleted all the time. You can put the mailstore on a SAN and access it from multiple SMTP and IMAP servers, but if the SAN goes down, everything is down. What I am trying to do is to distribute the mailstore over several locations and internet connections that function completely independently of each-other.
Hi, I don't think Gluster is the correct tool for the job: sync replication and file lookups will suffer tremendously due to the high latency WAN links, grinding all to an halt. Geo-replication should be out of question, because it is a read-only copy from source to dest (unless things changed recently).
For such a project, I would simply configure the SMTP server do to protocol-specific replication and use a low-TTL DNS name to publish the IMAP/Web frontends.
