In this tutorial I will describe how to set up postfix and maildir which can automatically replicate email when email is delivered. We will not touch the postfix configuration at all. we will manipulate maildir directory behavior using ChironFS, instead.
This the Chiron Filesystem. It is a Fuse based filesystem. It’s main purpose is to guarantee filesystem availability using replication. But it isn’t a RAID implementation. RAID replicates DEVICES not FILESYSTEMS.
Things we need before installing chironfs
- ChironFS source/binary from here
Compile ChironFS source
$ rpmbuild --rebuild chironfs-1.0.0-1.fc8.src.rpm $ rpm -ivh /path/to/chironfs-1.0.0-1.fc12.rpm
