ok, thanks Lars for your valuable answers. I have just also read that i do not 
need heartbeat for drbd to work. I just need to know from the experienced 
folk on this list wether its advantageous to have drbd with heartbeat, or 
drbd alone.

about syncing the services, must i install the high-availability services (say 
if i want http, dnd,pop3, http ) on the shared medium or just their 
configuration files? 

thanks in advance,
