Collection of Ansible playbooks for setting up Open CAS accelerated devices.
Default playbook configuration tries to configure Open CAS on opencas_nodes
host group from inventory.
Example configuration is shown in group_vars/opencas_nodes.yml.sample.
For default, out-of-the-box configuration you can only change the name to opencas_nodes.yml,
configure appropriate host groups and adjust the device names.
Default configuration is already present at roles/opencas-deploy/files/default.csv.
Any additional ioclass config files present in this directory will be copied over to
configured hosts and may be used in cache devices configuration in group variables.
