Chapter 6. CloudForms 4.2
The following section covers high availability options when using CloudForms 4.2 to include both native PostgreSQL HA and more traditional HA using pacemaker.
6.1. Built-in High Availability
With the release of CloudForms 4.2, there is a built-in database high availability option that simplifies the HA deployment and configuration for those interested in a basic configuration.
Refer to CloudForms 4.2: Configuring High Availability.[9] for configuration and setup.
6.2. pacemaker High *Availability
The process to configure CloudForms 4.2 with high availability using pacemaker is no different verses CloudForms 4.1.
CloudForms 4.2 does include an updated version of the PostgreSQL database, 9.4 to 9.5. This changes the path for the database:
Cloudforms 4.1:
/var/opt/rh/rh-postgresql94/lib/pgsql/
CloudForms 4.2:
/var/opt/rh/rh-postgresql95/lib/pgsql/
Bear this in mind when configuring CloudForms 4.2 high availability with pacemaker if following this reference architecture.
