I followed these steps correctly, everything worked well before I have revived heartbeat on node01 "at the last steps of the tutorial"
when I hit /etc/init.d/heartbeat start it started correctly but the webpage wouldn't open, in other words httpd service haven't been started by heartbeat (which I guess the reason is that the node02 still the primary node it hasn't returned to secondary yet)
so I searched for the STONITH but i didn't find anything that helps.
this is the ha.cf file:
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
initdead 120
bcast eth0
