[ClusterLabs] Floating IP active in both nodes

Dear cluster labs team.

I previously configured a two nodes cluster with replicated maria Db.
To use one database as the active, and the other one as failover, I
configured a cluster using heartbeat:

root at logpmgid01v:~$ sudo crm configure show
node $id="59bbdb76-be67-4be0-aedb-9e27d65f371e" logpmgid01v
node $id="adbc5972-c491-4fc4-b87d-8170e1b2d4d0" logpmgid02v \
attributes standby="off"
primitive site_one_ip ocf:heartbeat:IPaddr \
params ip="" cidr_netmask="" nic="eth0" \
op monitor interval="40s" timeout="20s"
location site_one_ip_pref site_one_ip 100: logpmgid01v
property $id="cib-bootstrap-options" \
dc-version="1.1.10-42f2063" \
cluster-infrastructure="heartbeat" \

Now, I've done a similar setup using corosync:
root at 908soffid02:~# crm configure show
node 1: 908soffid01
node 2: 908soffid02
primitive site_one_ip IPaddr \
params ip= cidr_netmask= nic=ens160 lvs_support=true \
meta target-role=Started is-managed=true
location cli-prefer-site_one_ip site_one_ip role=Started inf: 908soffid01
location site_one_ip_pref site_one_ip 100: 908soffid01
property cib-bootstrap-options: \
have-watchdog=false \
dc-version=1.1.14-70404b0 \
cluster-infrastructure=corosync \
cluster-name=debian \
stonith-enabled=false \
no-quorum-policy=ignore \

Apparently, it works fine, and floating IP address is active in node1:
root at 908soffid02:~# crm_mon -1

2018 by root via cibadmin on 908soffid02
Stack: corosync
Current DC: 908soffid01 (version 1.1.14-70404b0) - partition with quorum
2 nodes and 1 resource configured

Online: [ 908soffid01 908soffid02 ]

 site_one_ip (ocf::heartbeat:IPaddr): Started 908soffid01

But when node2 tries to connect to the floating IP address, it gets
connected to itself, despite the IP address is bound to the first node:
root at 908soffid02:~# ssh root at hostname
root at soffiddb's password:

I'd want the second node connects to the actual floating IP address, but I
cannot see how to set it up. Any help is welcome.

I am using pacemaker 1.1.14-2ubuntu1.4 and corosync 2.3.5-3ubuntu2.1

Kind regards.
