I have a linux server that currently running out of space in /home partition. I purchased a new HD, but don't know how to increase the size of /home partition, I.e. seamlessly add the new hd space to /home partition.

1. first
   Lets assume that your new HD is one partition mouned on /mnt/hdb1/
   You have many options:
   1)
   move some folders to the new HD and makelinks to them, like that
   mv /home/aVeryBigFolder /mnt/hdb1
   ln -s /mnt/hdb1/aVeryBigFolder/ /home/
   after doing that the folder aVeryBigFolder will appear in the /home dir, but it is actually stored on /mnt/hdb1/ (users will not feel any difference)

   2)
   use the new HD as your /home instead of your current home partition and move everything to it

   that's all options I know
