Hyper-v cluster instant failover

Question

Hello,

I installed hyper-v cluster on hyperconverged storage (datacore) and When I power off 1 server, HA occurs arround 2 min and 40 sec after with the following modifications :

(Get-Cluster).ResiliencyLevel = 1
(Get-Cluster).ResiliencyDefaultPeriod = 0

If I don't change it, I need to wait 4 min before isolated state is over and then it occurs.

Is there any solution for it to be instant when failure occurs ?

Thanks

My server is up to date and I think you did a mistake because the update you link is for 2020 and not 2021.

Does someone can say me if this is the normal behavior ?
