Description
In a cluster with 4 NetScaler, after disabling two nodes, the other nodes become inactive.
Resolution
From NetScaler release 10.5, you can configure the cluster to be functional even when the majority criteria is not satisfied. This is configurable with below command.
set cluster instance <clId> -quorumType <NONE | MAJORITY>
For a cluster to be functional, a majority of the nodes (n/2 + 1) must be operationally active (operational state is ACTIVE).
set cluster instance <clId> -quorumType <NONE | MAJORITY>
- "Majority" (recommended) requires majority of nodes to be online for the cluster to be UP. "None" relaxes this requirement.
- Default value for Quorum Type is Majority.
Problem Cause
This is by design.For a cluster to be functional, a majority of the nodes (n/2 + 1) must be operationally active (operational state is ACTIVE).
