I explain the catastrophe. I had a cluster with 3 hosts. Everything working perfectly, until I changed the MTU of the vmk and totally lost communication. I rebooted all 3 hosts and no virtual machines booted. No more vcenter vsphere (just failed to power on allways). All vm's show up with pathnames like /vmfs/volumes/vsan:xxxxx... nothing works.
So I installed another vcenter from scratch, and added the hosts to that cluster, configured everything again (this time with default MTU). But it turns out that all virtual machine objects seem to reference an old uuid from the previous vsan cluster. Disks are automatically claimed but with errors, ie inaccessible state.
Please i need to recover those virtual machines, at least the vmdk files that seem to have disappeared into nothing.
Don't ask me why I did such a thing in production. Nobody here knows anything and I have to guess and learn as I go.
