i have understand that.

now i have shutdown on my both servers the venus and have made the new 
venus-setup. the scm can start venus, but the non scm not. he brings often 
the failure, that he cannot find the rootvolume? 

scm ->	(venus-setup 1000000)
non-scm ->	(venus-setup 1000000) 

whats happend here?

the files under /vice/db are the same on both machines.
