ERROR_CLUSTER_INVALID_NODE_WEIGHT
NodeWeight changes are constrained by the active quorum model
ERROR_CLUSTER_INVALID_NODE_WEIGHT means the requested vote assignment is not safe or supported in the current configuration. The error specifically covers disk-only quorum and changes that would violate minimum quorum requirements. NodeWeight is an assigned vote setting, while dynamic quorum can separately change a node’s current vote as membership changes.
Inspect NodeWeight, DynamicWeight, witness state, and current membership before editing votes. Model the failure scenario the change is intended to support, including site loss and maintenance. Do not remove votes from enough active members to make the current partition unable to maintain majority. In most clusters, configure an appropriate witness instead of manually micromanaging votes.
Quorum values to calculate
- Assigned NodeWeight and current DynamicWeight for every node.
- Witness type, availability, and current vote.
- Current cluster membership and planned maintenance failures.
- Quorum mode, especially any legacy disk-only configuration.
