No, you have to stick the multi-disk setup command format
$ sheep /meta-store,/disk1,/disk2...
So in your case with multiple disks node, you need
$ sheep /mnt/sheepdog,/mnt/sheepdog/obj,/mnt/sdb1
The first component is the path to the meta-store, which was created at
/mnt/sheepdog/ when you started it with a single store path.
Actually, for a single store setup, A and B both are equal
A $ sheep /mnt/sheepdog
B $ sheep /mnt/sheepdog,/mnt/sheepdog/obj
