[ClusterLabs] MySQL Cluster: Strange behaviour when forcing movement of resources

Hi all, We are currently setting up a MySQL cluster (Master-Slave) over this platform: - Two nodes, on RHEL 7.0 - pacemaker-1.1.10-29.el7.x86_64 - corosync-2.3.3-2.el7.x86_64 - pcs-0.9.115-32.el7.x86_64 There is a IP address resource to be used as a "virtual IP". This is configuration of

[ClusterLabs] Ansible modules for basic operation with pacemaker cluster with 'pcs'

Hi Everyone, I have developed several ansible modules for interacting with pacemaker cluster using 'pcs' utility. The modules cover enough to create cluster, authorize nodes and add/delete/update resource in it (idempotency included - for example resources are updated only if they differ).

[ClusterLabs] question about equal resource distribution

Suppose I have a N node cluster where N > 2 running m*N resources. Resources don’t have preferred nodes, but since resources take RAM and CPU it is important to distribute them equally among the nodes. Will pacemaker do the equal distribution, e.g. m resources per node? If a node fails, will
