I ran into a similar problem with the Grizzly-3 Keystone release. I had to specify keystone.conf as the config-file with keystone-manage/ db_sync command otherwise it would not use the mysql statement in the keystone.conf file.

Someone on the IRC channel got me closer, but we have no idea why this would happen: this works: "root@test1:~# nova-manage --config-file=/etc/nova/nova.conf service list" Why would I have to specify the config file though? It is in the standard place.

No change. #3 - I changed the SQL connection string over to IP instead of hostname. No change. I didn't restart nova-api because it isn't running. If I understand correctly nova-manage communicated directly with the db, bypassing nova-api. This would appear true seeing "nova-manage service list" works correctly on test2. :( Thanks for the help!

'mysqladmin flush-hosts' 2. replace DNS entries in mysql.user table by IP addresses instead 3. modify /etc/nova/nova.conf with IP address of HA Mysql instead (and restart nova-api !) I wouldn't bet on it, but I would say this is due to some name resolution which is incorrect. -Sylvain Le 11/03/2013 17:00, Sylvain Bauza a écrit : Ok, lemme try to summarize. You do have a DRBD setup for MySQL bound to a VIP 10.21.1.1 thanks to Pacemaker. This setup is relying on two hosts, test1 (10.21.0.1) and test2 (10.21.0.2). Your nova.conf is pointing to mysql://10.21.1.1<http://10.21.1.1> which is the VIP. 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). 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). Also, as per my understanding of Pacemaker, DRBD partition is setup by default on test2, correct ? 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 ? 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 ? 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. -Sylvain Le 11/03/2013 16:09, Samuel Winchenbach a écrit : I enabled general_log in /etc/mysql/my.cnf Here are the results of connecting from "test1", "test2" and using the client: http://paste2.org/p/3115525 I purposefully used the real password in case there is a problem with it.
