So bottom line is to use a filesystem such as XFS, distribute and

Then you should also balance incoming mail and local deliveries and this
part is tricky. Also, there should
be a hearthbeat/pacemaker for filesystem/IP/services failover.
Every choice is a compromise. So you should balance a lot of factors:
complexity, administrative overhead, FS limits, performance, stability etc.
