Re: [Openstack] HA with pacemaker on Folsom

Hi Jean-Daniel, they have the default UID that were given to them when they were created on the system - so it' s not the same on both. As for the user, the mysql dir belongs to the mysql user and the rabbitmq to the rabbitmq user MySQL : 700 (/var/lib/mysql) RabbitMQ : 755 (/var/lib/rabbitmq) Regards, Razique Mahroua - Nuage & Co razique.mahr...@gmail.com Tel : +33 9 72 37 94 15 Le 16 avr. 2013 à 06:38, Jean-Daniel BUSSY <silversurfer...@gmail.com> a écrit : A ​re your mysql users have same id?​ What are the permissions of in your drbd fs when mounted on the master node?

Should I set pacemaker to change the userid befre starting the service first? Is that possible? I couldn't get corosync fired up with the upstart script and have to fire it on the frontend. Is the service script working for you? cheers BUSSY Jean-Daniel _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to     : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help   : https://help.launchpad.net/ListHelp
