Remediation Plan B:

  1. Shutdown all nodes but keep only one node active

  2. Restart that active node while other nodes are shutdown

  3. Start clustering with /fq.

    1. net.exe stop clussvc

    2. net.exe start clussvc /forcequorum

  4. Verify that disks are accessible in disk management in the active node, and start other cluster nodes
