ERROR_ALL_NODES_NOT_AVAILABLE

A cluster-wide operation requires full node participation

Some cluster changes require a consistent view or action across all nodes rather than quorum alone. A cluster can continue serving workloads with a node down and still reject an administrative operation that explicitly requires every node to be available.

Do not confuse service availability with operation eligibility. Quorum can be healthy while a cluster-wide configuration task waits for a missing node. Identify the unavailable node and the operation being attempted before changing quorum or failing over roles.

What to inspect

List all nodes and find any Down, Paused, or otherwise unavailable members.
Determine whether the node is intentionally under maintenance; finish or reverse that workflow before retrying the cluster-wide change.
If a node is permanently lost, follow supported node removal or recovery procedures instead of repeatedly retrying an operation that requires it.
