[PVE-User] Restoring files - /etc/pve not mounted after cluster create fail

[Gregor Burck]

Is there a way to repair the host after the cluster creation fail? Maybee it is faster than copy all the data,...

How I get information what goes wrong. Is there a log file of the creation 
process?

Additional boot error:
