I've been running a postgresql database on a drbd partition for about three 
years without a problem. Haven't lost any data. I installed postgresql to its 
default location on both nodes:

Then I created the data directory on my drbd partion which I called /mirror:

Then created a link to the data directory:

/usr/local/pgsql/data -> /mirror/usr/local/pgsql/data

I don't know how others have set it up, but this configuration has worked well 
for me.

Good luck,
