Cannot create separate storage pool on Windows 2019 Failover cluster.

Copper Contributor



I am trying to get rid of S2D on our failover cluster and came across the inability to create separate storage pools (without using S2D) on Windows 2016/2019. Every time you set up a Failover Cluster, even without adding eligible disks to storage, it still sets up the Clustered Windows Storage subsystem and assigns all available disks to it. So, you have all the disks, but if you try to create a storage pool, it will fail.


Tried to create all storage pools before forming the cluster - to no avail, the pools were created, but any attempt to create a virtual disk instantly fails. I tried to use Set-ClusterS2DDisk to stop the storage subsystem from using those disks - to no avail. Tried to unregister the Clustered Windows Storage subsystem - it's not possible. I have absolutely no idea what to do now.


So, is there a way to set up a failover cluster without using S2D?

As a workaround, you can try evicting a node from the cluster for creating a local pool on it and then add this node back. Repeat for all nodes one by one.
