Forget to mention, After launching ESXi Installer, before hitting ALT+F1 to get into console, process forward to get list of Storage Objects and Datastores go get all Datastores mounted.
Also if some mod could edit first post, it's obviously "nfs4client" not "ntfs4client".
We are having this exact issue. We can't find any of the swap files. Our boot drive is on a USB drive. Where exactly would the system datastore be?
