Dell provides the OneFS installation bundle for:
Each bundle contains the OneFS image and the most recent RUPs that have been verified by Dell. We support any types of the RUP except the node firmware package (NFP) and drive support package (DSP). The specific supported types of RUP are:
With the most recent RUP, OneFS can provide the most enhanced reliability and stability. You can download these bundles for multiple OneFS releases including:
The installation process is the same as the one that does not include RUPs. It supports rolling upgrade, simultaneous upgrade, and parallel upgrade. It also supports rollback operations.
In OneFS 9.1.0.0, this feature provides the following improvements:
These new features are explained in the following sections.
Starting from OneFS 8.2, installing patches during a OneFS upgrade is supported by using the newly introduced parameter ‘--patch-paths’.
OneFS 9.1.0.0 supports using the ‘--patch-paths’ parameter along with the pre-package OneFS image with RUPs.
In this case, the embedded RUP and the user input patches using ‘--patch-paths’ may have conflicts. To deal with these conflicts, internally we have some complicated rules defined. However, in order to simplify these rules, see the following typical cases:
Scenarios | Upgrade From | Upgrade image | --patch- paths | Compatibility | Outcome |
Scenario I | OneFS 8.2.2 | Pre-package image: OneFS 9.1.0.0 + RUP v1 + KRUP v1 | RUP v2 and KRUP v2 | Yes | OneFS 9.1.0.0 + RUP v2 + KRUP v2 |
Scenario II | OneFS 8.2.2 | Pre-package image: OneFS 9.1.0.0 + RUP v2 + KRUP v1 | RUP v1 and KRUP v2 | No | OneFS 9.1.0.0 + RUP v2 + KRUP v2 A CELOG event raised |
Scenario III | OneFS 8.2.0 | Pre-package image: OneFS 9.1.0.0 + RUP v2 | RUP v1 | No | OneFS 9.1.0.0 + RUP v2 A CELOG event raised |
Dell Technologies recommends using precheck operation to run the preliminary check between embedded RUP and user input patches to ensure that there is no conflict before starting an upgrade.
Group change happens during the OneFS upgrade and this process can impact the protocol latency in the upgrade process. In OneFS 9.1.0.0, this period of time has been highly improved to only one second to help better data availability.
