    Looks like you've enabled vSAN without actually having done any configuration or disk claiming--possibly because you don't have the necessary types of disks. Does this sound like what you've done?

    Hello inspirer​,

    It could be a number of things:

    - Check that the cluster is fully-formed - if nodes are isolated from one another then vsanDatastore will show as 0 size (check cluster membership via SSH with #esxcli vsan cluster get).

    - Check your VASA Providers for all hosts in this cluster are registered, active and functioning correctly (if they are not try resync, rescan and/or check certs).

    - Check that all hosts are communicating with vCenter okay - vSAN Health check in the Web Client helps here - if this doesn't display at all then you likely have a communication or clustering issue.

    - Check for anything weird in the vmkernel.log/dmesg of the current cluster Master (identifiable via SSH with #esxcli vsan cluster get) e.g. 'failed to map MPNs'.
