ansible-hacluster

Role to create a two node ha cluster using pcs, pacemaker and corosync.

Requirements

Code is partially tested in RHEL 7 and Debian specific code is under development. Tasks for creating fencing device is in virtfence.yml should be considered as a hint and please make necessary changes. It is under testing and unsafe code is commented out.

Role Variables

Follwing variables in defaults/main.yml should be set to your environment

hacluster_password: Change_Me
pcs_cluster1: set_an_ip1
pcs_cluster2: set_an_ip2
cluster_name: set_name
virt_fencing: false
ip_of_esxi: set_esxi_or_vcenter_ip
sxi_username: set_esxi_or_vcenter_username
sxi_password: set_esxi_or_vcenter_password

Tasks under virtfence.yml is disabled when virt_fencing is set to false.

Dependencies

As of now no dependency. However I have plans to fork fencing code to separate role.
