The implications include a complete loss of any pre-existing data, necessitating a comprehensive backup and restoration strategy if data preservation is required. The ISO file provides the necessary components to format the drives and install the operating system without relying on any previous system state.
-
Upgrade Installation
An upgrade installation maintains the existing data and system configuration while updating the operating system to a newer version. This method is appropriate for systems already running a previous version of TrueNAS SCALE or a related operating system. A typical scenario involves a home user upgrading their existing TrueNAS SCALE installation to the latest version to benefit from new features and security updates. The ISO file provides the necessary components to replace the existing system files without reformatting the storage devices. This method is less disruptive than a fresh installation, but carries the risk of compatibility issues or data corruption if the upgrade process is interrupted or encounters unforeseen errors.
-
Importing Existing Pools
Regardless of the installation type, the process of importing existing ZFS pools is relevant if the system previously utilized a ZFS-based storage solution. This process allows the newly installed TrueNAS SCALE instance to recognize and access existing data stored on the drives. For example, if a user migrates from a different ZFS-based operating system, they can import their existing storage pools into TrueNAS SCALE. The installation ISO enables this by providing the necessary ZFS tools and drivers to recognize and mount the existing file system. This step is critical for maintaining data accessibility and preventing data loss during the transition. Without proper pool import, the data remains inaccessible, requiring potentially complex recovery procedures.
In summary, the installation type chosen dictates how the acquired TrueNAS SCALE installation image interacts with the target system. A fresh installation offers a clean slate but requires data migration, while an upgrade preserves existing data but carries the risk of compatibility issues. The ability to import existing ZFS pools ensures data continuity regardless of the chosen installation type. These considerations are crucial for planning and executing a successful TrueNAS SCALE deployment, mitigating potential data loss or system instability. The selection should align with the specific needs and constraints of the environment, balancing the desire for a clean installation with the need to preserve existing data and configurations.
7. Storage space
The correlation between storage space and the TrueNAS SCALE installation image primarily manifests in two distinct phases: the initial download and subsequent installation.
