Provisioning¶
The system is installed as a loosely bundled set of applications. In order for the applications to be coupled, a process called ‘provision’ must take place.
Standalone systems are single-node (“cluster-of-one”) clusters and are provisioned automatically since there is only one node in the system. This can be performed manually afterward with cluster provision.
When the topology of the cluster changes, e.g. additional nodes or applications are added; or to reprovision the system to bypass a faulty node, the cluster must be reprovisioned using cluster provision.
Note that for multi-node clusters, the cluster provisioning needs to reconfigure and restart services across the cluster in a complex arrangement and the provisioning duration is dependent on the number of nodes - it can take a number of hours for large installations.
Provision the cluster from the primary node with cluster provision For backwards compatibility, this command is the same as for example cluster provision fast.
Use the cluster provision serial command if the VMware host is under load.
The provisioning step may take some time, because all applications must be cross-configured to work with one another and the database is also provisioned. If the system discovers that no primary database server exists (or multiple database servers exist), the cluster provision command prompts the user to select a primary server manually.
