<div>Ok, lemme try to summarize. <br>
You do have a DRBD setup for MySQL bound to a VIP 10.21.1.1
thanks to Pacemaker. <br>
This setup is relying on two hosts, test1 (10.21.0.1) and test2
(10.21.0.2).<br>
Your nova.conf is pointing to mysql://<a href="http://10.21.1.1" target="_blank">10.21.1.1</a> which is the
VIP.<br>
<br>
Are you sure your my.cnf is actually the same in between both
DRBD nodes ? (I would recommend to symlink it to a physical file
hosted on the DRBD device).<br>
<br>
One thing is hurting me : you told me that nova is also
pacemake'd. If so, why can I still see my_ip=10.21.0.2 (test2) ?
It should be pointing to nova-ha (assuming 10.21.2.4 as per
/etc/hosts).<br>
<br>
Also, as per my understanding of Pacemaker, DRBD partition is
setup by default on test2, correct ?<br>
<br>
<br>
Sorry, as per my first reading, I can't see anything obvious.
That said, I'm not sure this is a Nova bug, as the tcpdump trace
is seeing a correct MySQL connection attempt. But maybe I'm
wrong ?<br>
<br>
Anyway, are you sure you only have *one* MySQL engine running
(either on test1 or test2) and nova-manage trying to access this
right one ?<br>
<br>
Perms look good to me. As it a test setup, you could try to
unleash the grants by deleting them and allowing nova@'%' to see
if it's a basic dns mapping issue.<br>
