Betreff: [lvs-users] Connecting to service from behind VIP
Hi all,
I am setting up a three node OpenStack cluster that I would like to make
highly available. One of the services OpenStack requires is a database,
so I installed Percona XtraDB Cluster on the three nodes.
At this point I thought "Hey, why not load balance the connections to the
cluster?" so I installed ldirectord on one of the nodes, and configured all
three nodes as the reals. What I noticed is this:
* I have no problem when connecting from the node running ldirectord (wrr
works fine and connecting to all the real servers works great)
* If I connect from one of the other database nodes the only real that
works correctly is the one running ldirectord. It does not work when
connecting to the node I am connecting from, or the other non-ldirectord
node.
Here is a little paste that kind of shows what I am doing:

Any idea on what might cause this? Also if you have ideas or suggestions
on something that might be cleaner or more elegant that would be wonderful.
I do not have resources to move ldirectord to dedicated node(s). I could
just use pacemaker and assign a VIP to one of the nodes running Percona and
forget about load balancing the cluster.
Thanks for any tips you might have!
Sam
