Hello,
Microsoft shared with us the PowerShell way to customize the cluster resiliency settings in a Windows Server 2016 Hyper-V cluster.
| Setting
|
Description | Default | Values |
| ResiliencyLevel | Defines how unknown failures handled | 2 | 1 – Allow the node to be in Isolated state only if the node gave a notification and it went away for known reason, otherwise fail immediately. Known reasons include Cluster Service crash or Asymmetric Connectivity between nodes.2- Always let a node go to an Isolated state and give it time before taking over ownership of the VMs. PowerShell: (Get-Cluster).ResiliencyLevel = <value> |
| ResiliencyPeriod | Duration to allow VM to run isolated (in seconds) | 240 | 0 – Reverts to pre-Windows Server 2016 behavior
PowerShell: Cluster property: (Get-Cluster).ResiliencyDefaultPeriod = <value> Resource property for granular control: (Get-ClusterGroup “My VM”).ResiliencyPeriod= <value> A value of -1 for the resource property causes the cluster property to be used.
|
| QuarantineDuration | Duration to disallow cluster node join (in seconds) | 7200 | 0xFFFFFFFF – Never allow node to join (in seconds)
PowerShell: (Get-Cluster).QuarantineDuration = <value> |
You’ll find more details here, and here.
