Hi Zahid,
when setting up a database cluster with initdb, you determine the
directory path for the cluster.
So make sure the directory path resides on the disk you want it to be.
What is also possible is using a symbolic link to redirect to another
directory on the intended disk.
On the other hand, it's not possible to have some databases of a cluster
on one drive and some on another. A database cluster cannot be
distributed among disks.
Since you can have any number of database clusters on a machine, this
doesn't impose a problem.
Regards,
Holger
