Glossary
Definitions for commonly used terms in MapR Converged Data Platform environments.

Disk Capacity and Preflight

The disk capacity and preflight checks performed during the creation and updation of an air-gapped repository.

Ensure that the host running airgap repo container has sufficient disk space to accommodate current available repository data , preflight downloads, inactive publications. The airgap-repository update operation does not take care of ensuring that the disk space availability constraints are satisfied.

NOTE

An update temporarily requires storage for all of the following:

The stable archive cache, including any newly downloaded archives.
The current active publication.
The candidate publication, including additional package branches.
Configured minimum free-space headroom. Any retained inactive publication directories, legacy caches, or failed staging content already on the filesystem.

Every create and update runs a disk capacity and preflight check, by default.
