Force VSAN to use unaccessible objcect that are local to the host

Hi all,

I'm interested in one information that I cannot find anywhere.

Consider a simple 2 Nodes + Witness solution (Small Business/ROBO)

Consider this timeline:

1- Witness Fail : I have still 2 copies of data, so full data redundancy (and no witness), but ok with quorum

2- Secondary host fail: primary host have all the data uncorrupted, but have no quorum. All objects unaccesible

In this situation, is there a way, with or without opening a case to the support, to force VSAN to run with only 1 node and no quorum (like the first setup of VCenter on top of the same VSAN cluster, where you have only one node of VSAN and VCenter works)?

If yes, is it also possible with the secondary server up and the primary down?

Does the deployment of a NEW witness recover all my unaccessible objects?

Thanks

Manuel
