#Vertica Installs Vertica either standalone or part of a cluster.

Tested with Vertica 7.x

##Requirements

• vertica_ssh_key_location - location of where to create and place ssh keys for dbadmin
• vertica_dbadmin_password - password to be used for dbadmin on the database mon

##Optional parameters

• run_mode: One of Deploy, Stop, Install, Start, Logging, or Recover. The default is Deploy which will do Install, Configure, then Enable. 'Start' and 'Logging' can only be run after the database is created via Monasca-schema. Recover can be used to bring the vertica cluster back up from a failed state.
• vertica_database_name: Database name for the vertica database. Must be the same as in set in Monasca-schema. Defaults to mon.
• vertica_license - Production license key to use when creating the database. By default the role will use the community license.
• vertica_use_apt: If True, vertica will be install from the apt repository. If False, it will be installed from the given local package. Default is False
• vertica_version: If set and vertica_use_apt is True, then the given version will be installed

If the variables vertica_cluster and vertica_group are both defined the nodes will be setup to be in a cluster.

vertica_cluster is a common separated list of the group of nodes that you want to be apart of your cluster and vertica_group is set to that group from the ansible inventory file.

See the example playbook below.

Other notes

Vertica recommends setting the kernel disk scheduling algorithm to deadline. This can be done by adding the kernel bootparam "elevator=deadline" then restarting. This optimization is not done by the role.

This role does not create the database. That creation is in the role Monasca-schema

##Example Playbook

hosts: vertica
sudo: yes
roles:
  - {role: vertica,
     vertica_group="{{groups['vertica']}}",
     vertica_cluster="10.10.10.1,10.10.10.2,10.10.10.3",
     tags: [vertica]}
