network question about harddrives
 

i've set up a cluster, and one of my machines has more hard drive space than the others. Is there a way to change the /home and /usr/src of all the nodes to read off of the one? How would I move those directories to a harddrive that was installed after the installation? just the mv command?

I don't know if you are using NFS. You can have /usr mounted on a network device (in the /etc/fstab). There is an option which makes sure that the share isn't mounted until the network daemons are finished running. You could do the same with the /home partition, you could could locate the home directories of the users on a network device. A users home directory is given in the /etc/passwd file.
