Hi Stephane, Once I have tested my settings, I am planning to use it in production version. That's why I thought of using GA release( https://github.com/tanji/replication-manager/releases/tag/1.0.0).
But please send me for the below details, So I will test my settings: OS : CentOS 7 Maria DB : 10.1.17 Maxscale : 2:0 Hi Guillaume, Thank you for your input. In order to make MRM independent from Maxscale, I don't need to configure to execute as script via mysql Monitor section of maxscale for event=master_down? Also can you share me some documentation to understand this better, I am little bit new to this technology and facing little challenge to understand these below: Also I am planning to use pcs-corosync to make maxscale(Active-standby) HA.
