More than one device on a host

One again my config:
one storage node.
dev1 is on /database/mogdata/dev1
dev2 is on /dev2/mogdata/dev1
in mogstored.conf:
docroot=/database/mogdata
I think mogstored is able to find dev 1 because it is the docroot but not able to find dev2. Should it be like
docroot=/database/mogdata; /dev2/mogdata/dev1 ??????
Permisions are set, but dev2 is not bound!
