PowerScale OneFS Upgrade Planning and Process Guide
Consider upgrade limitations
If the upgrade cannot be completed for any reason—for example, if there is insufficient space on the cluster or if the upgrade process detects a stalled drive—the system will revert to the current version and the upgrade will be cancelled. Preparing your cluster as recommended in this guide will help you to avoid situations that might result in a cancelled upgrade.
NOTE:In OneFS 8.2.0 and newer, you have the ability to pause and resume the upgrade process in order to resolve blocking issues.
