Hi Karthick,

(disclaimer: I am one of the authors of Replication Manager for MariaDB)

you seem to be using outdated instructions. Please grab the 1.0.2 release for your distribution there: 

https://github.com/tanji/replication-manager/releases

Replication Manager works best when used independently from MaxScale. Please read our documentation at https://github.com/tanji/replication-manager/blob/develop/README.md and let me know if you have any questions.

Best

Guillaume

Hi Experts,

I have a 2 db server with one as master and another one as slave. 

Maxscale implemented with below monitor config:

[MySQL Monitor]

type=monitor

module=mysqlmon

servers=master1,slave1

monitor_interval=500

script=/usr/bin/replication-manager --user root:password --rpluser replusr:password 

--hosts $INITIATOR,$NODELIST --failover=force --interactive=false

events=master_down

When I shutdown master, failover is not automated. MRM (Replication Manager) is not promoting the slave to master automatically. 

In maxscale log, I noticed below:

2017-03-02 03:33:36   notice : Executed monitor script '/usr/bin/replication-manager --user root:password --rpluser replusr:password --hosts $INITIATOR,$NODELIST --failover=force --interactive=false' on event 'master_down'.

2017-03-02 03:33:36   error  : No Master can be determined.

Is this because I didn't have the quorum (no slave) since its one master and one slave set-up. Is there any workaround. 

Regards,

Kart
