I am so sorry for the confusion. I was using heartbeat and could not
get it to work so I switch over to corosync. <br>
Yes, I do have two NIC and two network cables. One crossover cable
connected to eth0 on both nodes for DRBD replication. Other cable
connect to the LAN for heartbeat. thank you very much for your
help. <br>
<br>
Node1(192.168.1.140-eth1) --> connect to LAN
<---Node2(192.168.1.150-eth1)<br>
Node1 (10.0.0.10-eth0-DRBD)<--cross over
cable---->Node2(10.0.0.20-eth0-DRBD)<br>

<pre wrap="">Hello everyone,
My goal is to build a HA DRBD and MYSQL on two nodes(active/passive). I
followed the " cluster from scratch" article to build this environment.
If I do standby failover host, it works fine but when I pull the
heartbeat cable from the active node, the resources do not fail over to
the secondary. Please advise. Thank you very much. Joe

<pre wrap="">
* "the" heartbeat cable == one heartbeat cable? Not supported setup --
use at least two heartbeat channels, add at least the DRBD replication
network.
* you produced a split brain situation. I'd expect you see errors in
your cluster status and see DRBD log entries with a wording similar to
"not allowed to become primary because allow-two-primaries is not set"
... if you had also pulled DRBD link you would have all resources
running twice
* use stonith to recover from a split-brain situation (or block if its
unsuccessful)
* read more manuals ;-)

These ids are from Heartbeat CCM ... but you attached a Corosync
configuration? Decide for one ... either Heartbeat or Corosync.
