Support for Windows failover clustering

It worked even if I enabled S2D while keeping it as SATA and IDE, and then changed it to a SCSI HDD.
However, I don't know if it will work if I switch HDDs.

That sounds good so far. I am not sure how you configured your servers to use the same disk? Can you provide an example of a working config for two servers sharing a virtio disk using S2D? Thanks.

1. Create a VM with IDE and SATA disks as shown below.

2. Start the VM and install Windows Server, create a Hyper-V cluster, and create S2D.

3. After creation, stop the cluster and shut down both VMs.

4. Change the settings as follows.

5. Start the VM and check the Hyper-V cluster status.

Hi aslopez_irontec,

We have used a very similar config for the two vms but the cluster verification test fails. It also fails with sata disks.

What kind of storage is your "pool-vms"?

Can you show the config of your second windows vm too please?

Here is our config:
