I want to access the web site if master server is down.

My /etc/maxscale.cnf is:

[Read-Write Service]
router_options=master_failure_mode=error_on_write

I have two servers:

server1 | 127.0.0.1 | 3311 | 0 | Slave, Running
server2 | 127.0.0.1 | 23307 | 0 | Master, Slave of External Server, Running

I can access the web site at this time.
Then I stopped the server2.

server1 | 127.0.0.1 | 3311 | 0 | Slave, Running
server2 | 127.0.0.1 | 23307 | 0 | Down

I can still access the web site because of having option error_on_write.
Then I restarted maxscale daemon.

server1 | 127.0.0.1 | 3311 | 0 | Running
server2 | 127.0.0.1 | 23307 | 0 | Down

I can't access the web site because of database error.
I want to access the web site if master server is down.
