We are using Hyper-V on a S2D cluster of three nodes. Each node has two NVME SSD's and 8x SAS 1.2TB drives. The NVME SSD's are currently assigned in the performance Tier and the 8 drives are assigned in the capacity tier. On the VM's running in the cluster I am experiencing poor disk performance. I investigated the issue and noticed that the cache has been disabled for S2D.
I enabled the S2D cache with the 'Set-ClusterS2D -CacheState enabled'. The command is returning No disks found to be used for cache. The NVME drives are already part of the storage pool I created earlier. Is there are way to remove the NVME drives(without disruption) from the pool so I can use them as cache device?
