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@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="192.168.2.200" cidr_netmask="255.255.252.0" 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" \ stonith-enabled="false" Now, I've done a similar setup using corosync: root@908soffid02:~# crm configure show node 1: 908soffid01 node 2: 908soffid02 primitive site_one_ip IPaddr \ params ip=10.6.12.118 cidr_netmask=255.255.0.0 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 \ maintenance-mode=false Apparently, it works fine, and floating IP address is active in node1: root@908soffid02:~# crm_mon -1 Last updated: Fri Oct 26 10:06:12 2018 Last change: Fri Oct 26 10:02:53 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@908soffid02:~# ssh root@10.6.12.118 hostname root@soffiddb's password: 908soffid02 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. Gabriel Buades
