Hi [NAME],   I've checked ME5 release notes, it's not a feature enablement in firmware, but the feature is already by designed in ME5. Hence, ME4 is unable to expand the base volume and ME5 is able to.
In the admin guide for the ME4 series it says "You cannot expand the base volume of a snapshot tree or any snapshots in the tree." From this statement it sounds like a volume that has snapshots cannot be expanded unless those snapshots are first deleted. Am I correct? In the admin guide for the ME5 series it says "You can expand the base volume of a snapshot tree, but you cannot expand any snapshots in the tree." Is expanding the base volume of a snapshot tree a new feature in the ME5 series, or is this a print error in the guide? Or is it a feature that is available with the latest firmware? Thanks.
