Hi,
Our system manages the database (one master and multiple slave). We use one VIP
for multiple Slave resources firstly.
Now I want to change the configuration that each slave resource has a separate
VIP. For example, I have 3 slave nodes and my VIP group has 2 vip; The 2 vips
binds to node1 and node2 now; When the node2 fails, the vip could move to the
node3.
[cid:image002.png@01D3ACB5.53E7BAF0]
I use the following command to add the VIP
pcs resource group add pgsql-slave-group pgsql-slave-ip1 pgsql-slave-ip2
pcs constraint colocation add pgsql-slave-group with slave pgsql-ha
INFINITY
But now the two VIPs are the same nodes:
Master/Slave Set: pgsql-ha [pgsqld]
Masters: [ node1 ]
Slaves: [ node2 node3 ]
pgsql-master-ip (ocf::heartbeat:IPaddr2): Started node1
Resource Group: pgsql-slave-group
pgsql-slave-ip1 (ocf::heartbeat:IPaddr2): Started node2
pgsql-slave-ip2 (ocf::heartbeat:IPaddr2): Started node2
Could anyone tell how to configure to make each slave node has a VIP?
Thanks
