Thanks for advice. It seems that load balance is not an option and the failover is the only case. By the way does anyone tried, thought about implementing the case with Zookeeper functionality? As I said, I personally haven't met the situation when load balancing required or even failover required, but it might be for intensive API-centric deployments it's an option? 2017-07-18 22:32 GMT+07:00 Paul Angus : > Be careful with your load-balancing Ivan - Since CloudStack relies on > MySQL=E2=80=99s GET_LOCK and RELEASE LOCK, multi-master isn't supported. > > http://www.shapeblue.com/how-to-deploy-high-availability- > cloudstack-with-mariadb-galera-cluster/ > > > > Kind regards, > > Paul Angus > > paul.angus@shapeblue.com > www.shapeblue.com > 53 Chandos Place, Covent Garden, London WC2N 4HSUK > @shapeblue > > > > > -----Original Message----- > From: Ivan Kudryavtsev [mailto:kudryavtsev_ia@bw-sw.com] > Sent: 18 July 2017 16:08 > To: users@cloudstack.apache.org > Subject: ACS 4.9.2 Management Server and Galera Cluster in CentOS 7 > > Hello, community. > > A person asked me whether i have experience of deploying ACS 4.9 with > Galera HA cluster and after I answered - "I don't" I decided to try becau= se > I was unable to find relevant new article I wrote it as well.
