Hi Team,

I am working on project where i need to configure MS Failover Cluster on top of OpenStack Cloud.
my question is simple, as MS guy, what kind of Disk i should ask?
as per my understanding shared Disk should work here but still need to know what type of storage i ask from Openstack team.
As per openstack team, they are providing RAW Disk .

NOTE: FC can create but storage its says"its not applicable"

<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='/dev/disk/by-path/pci-0000:33:00.0-fc-0x5006016d48a00cdf-lun-240' index='4'/>
<target dev='vdb' bus='virtio'/>
<alias name='virtio-disk1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>


Please help !!

    Storage should be available for every node in the cluster. I don't have much experience, but if I understand OpenStack shared disk correctly, yes it should work. Check the requirements.

    It should be something similar to VMware shared VMDK, which are used to deploy Failover Clusters on VMware vSphere nodes.

    In case, you won't be able to use shared disks, you can utilize local storage and use StarWind VSAN to create replicated shared storage pool for Failover Cluster. The following guide covers the configuration process: https://www.starwindsoftware.com/resource-library/starwind-virtual-san-for-hyper-v-2-node-hyperconverged-scenario-with-windows-server-2016/
