How your system is affected when you apply a hotfix

You must understand how your StorageGRID system will be affected when you apply a hotfix.

Client applications might experience short-term disruptions

The StorageGRID system can ingest and retrieve data from client applications throughout the hotfix process; however, client connections to individual Gateway Nodes or Storage Nodes might be disrupted temporarily if the hotfix needs to restart services on those nodes. Connectivity will be restored after the hotfix process completes and services resume on the individual nodes.

You might need to schedule downtime to apply a hotfix if loss of connectivity for a short period is not acceptable.

Alarms might be triggered

Alarms might be triggered when services start and stop and when the StorageGRID system is operating as a mixed-version environment (some grid nodes running an earlier version, while others have been upgraded to a later version). In general, these alarms will clear when the hotfix completes.

Many emails are generated

When you apply a hotfix to grid nodes, email notifications are generated when nodes are stopped and restarted. To avoid excessive emails, you can disable email notifications before the hotfix is applied to the first node and re-enable notifications after the hotfix has been applied to all nodes.

Configuration changes are restricted
