Host Error -- Unable to apply DRS resource settings on host (Reason: The operation is not allowed in the current state.).This can significantly reduce the effectiveness of DRS.

I have defined 3 root resource pools in my cluster. The total CPU resource is 60G and I set the Reservation for each root resource pool to 18G. The total memory resource is 80G and set the the momery reservation for each resource pool to 25G.

Recenty, some host often show error. I checked the events of the host and there are a lot items such as:

Unable to apply DRS resource settings on host (Reason: The operation is not allowed in the current state.).This can significantly reduce the effectiveness of DRS.

the details of the event doesn't have more information, so don't know what problem is.

I wonder if the configuration of the resource pools are incorrect. How should I do?

I tried decreasing CPU and memory reservation of the 3 resource pools to leave more resource for DRS's actions. The unreservation resource is almost 30% of total. then this error seldom happens, but sometime it still happen. what should I check next?
