i tested
DRBD with ocfs
which works nice, also did tests with linux ha

perhaps this helps

cant get GFS run on ubuntu ( maybe my fault )

didnt test dovecot and postfix setup implemented in the ha-lb-cluster
yet ( but ocfs was reported to work nice with dovecot deliver as far i
remember), i used only apache http service for testing, but that worked nice
in a vmware testing field with 4 servers ( 2 redundant loadbalancer and
2 Ha Servers )
