Quorum resources cannot participate in ordinary dependency chains
Resource dependencies control startup and failure relationships inside clustered roles. The quorum resource is cluster infrastructure, not an application provider resource, and Windows explicitly prevents attaching ordinary resource dependencies to it.
If an application appears to need the quorum resource as a dependency, the role design is wrong. Applications should depend on their actual service prerequisites such as storage, IP Address, Network Name, or another application-specific provider resource.
What to inspect
- Inspect the intended dependency graph and identify the real prerequisite the application resource is trying to represent.
- Keep quorum or witness configuration separate from clustered-role dependency design.
- Remove any automation assumption that the witness or quorum resource can be used as a generic availability gate.
