When planning an upgrade to StorageGRID 11.4, you must consider when to upgrade, based on how long the upgrade might take. You must also be aware of which operations you can and cannot perform during each stage of the upgrade.
The time required to complete a StorageGRID upgrade depends on a variety of factors such as client load and hardware performance.
Upgrade stage | Description | Approximate time required | During this stage |
---|---|---|---|
Pre-upgrade validation | The grid’s condition is validated. | 3 minutes per grid node, unless validation errors are reported | The upgrade is not yet running. As required, you can perform this step before the scheduled upgrade maintenance window. |
Primary Admin Node upgrade | The primary Admin Node is stopped, upgraded, and restarted. | 30 minutes | You cannot access the primary Admin Node. |
Upgrade of all other grid nodes | The software on all other grid nodes is upgraded, in the order in which you approve the nodes. Every node in your system will be brought down one at a time for several minutes each. | 15 to 45 minutes per node, with appliance Storage Nodes requiring the most time |
|
Cassandra database update | Storage Nodes only. The upgrade process stops the Cassandra service, checks each node to verify that the Cassandra database does not need to be updated, and restarts the service. | 3 minutes for each Storage Node | |
Restart services | Some grid node services are restarted. Affected grid nodes might be shown as Administratively Down. |
15 minutes per node | |
Complete final steps | The upgrade to the new release completes. | 5 minutes | When the final upgrade steps complete, you can:
|
630 minutes (14 × 45 minutes/node) + 27 minutes (9 × 3 minutes/Storage Node) + 60 minutes (Admin Node and final steps) ----------------------------------------- 717 minutes (~12 hours)
