Dear Stephen, Thanks a lot. I really appreciate your support. So According to your mail I will try to setup high availability setup (with drbd); I am following these steps; * Install ricci and luci (luci only on master system) * Install cman ( On both systems) *Install rgmanager(on both systems) * install drbd( on both systems) * Create cluster ( Without shared storage option as mirroring will be done by drbd) * configure FTP on both systems Please correct me if I am wrong.
