2017-05-03IPv6 VIP addresses need to be /128Michele Baldessari1-6/+14
We currently hardcode /64 as our VIP addresses when using IPv6. The problem with this is that some server code might bind to that IP as a source address when doing inter-cluster communication (rabbitmq/galera for example). So when the VIP moves there will be effectively a network outage between the nodes, which should not happen. Likely this was hardcoded to /64 because the RA IPaddr2 needs a nic parameter when /128 is specified. This is due to: https://bugzilla.redhat.com/show_bug.cgi?id=1445628 We also make sure we use the ipv6_addrlabel option set to 99 so that they will never be used as source ip addresses.

2017-01-25Composable HAMichele Baldessari1-12/+40
This commit implements composable HA for the pacemaker profiles. - Everytime a pacemaker resource gets included on a node, that node will add a node cluster property with the name of the resource (e.g. galera-role=true) - Add a location rule constraint to force running the resource only on the nodes that have that property - We also make sure that any pacemaker resource/property creation has a predefined number of tries (20 by default). The reason for this is that within composable HA, it might be possible to get "older CIB" errors when another node changed the CIB while we were doing an operation on it. Simply retrying fixes this. - Also make sure that we use the newly introduced pacemaker::constraint::order class instead of the older pacemaker::constraint::base class. The former uses the push_cib() function and hence behaves correctly in case multiple nodes try to modify the CIB at the same time.

2016-04-13Refactor HAproxy and VIP creation.Sofer Athlan-Guyot1-0/+64
In tripleo heat template, overcloud_controller_pacemaker.pp has a lot of duplicate code to define haproxy and vip creation. This is an attempt to refactor this. Change-Id: I4cc6711911c1bfa1bc6063979e2b2a7ab5b8d37b
