Storage Volumes and Scope

We have seen that a Storage Class can restrict the Storage Volume scope within its definition. This scope governs the creation (but not the usage) of volumes, here’s the implications:

  • group: Owners of a group can create Storage Volumes for their groups. This excludes the user’s personal group.
  • user: Single users can create Storage Volumes for themselves.
  • all: There is no scope restriction.

Why do these settings fail to control the usage scope?

Because Storage Volumes created within a user group are usable from any groups a user is member of, this allows by example a user of the group Apple to use their home directory while running workflows from the group Apple.
