Hi, The root cause was recently fixed here: https://github.com/apache/cloudstack/pull/757/files
As a workaround you can either alter the query (as mentioned below) or downgrade mariadb: systemctl stop mariadb yum -y remove mariadb-libs yum -y install mariadb-1:5.5.41-2.el7_0.x86_64 mariadb-server-1:5.5.41-2.el7_0.x86_64 systemctl start mariadb Regards, Remi Sent from my iPhone On 12 Sep 2015, at 00:59, giraffeg forestg <giraffefore...@gmail.com<mailto:giraffefore...@gmail.com>> wrote: Hi CLOUDSTACK-8212 might become your help. https://issues.apache.org/jira/browse/CLOUDSTACK-8212 1.
