I highly recommend getting more disk space for your /home directory - that might be easier to administer in the long run.
Actually our /home is off another NFS file server entirely (not from Oscar) - this is because the /home directory is also mounted on all other regular workstation computers running linux.
I guess it is sort of wasteful to have a 40g HD using only 600megs, but the key to the Oscar cluster is having centralized storage - this means the user only has to put a file in one location and they will appear on all the other nodes.
Cheers,

Hi Reuben:
I'm not entirely sure, but I believe SystemImager actually image your entire disk. So I don't think what you want to do is achievable (someone correct me if I'm wrong).
For our cluster, we simply have a NFS shared out /home directory and have found out that OSCAR is quite tolerant with that (i.e. it doesn't blow the NFS files to bits ;-) ).
What you might also consider is putting another HD into that computer so that OSCAR can install the image onto it and then mount the /home directory accordingly.
OK. We do that with /home (NFS exports to nodes from master), but it's getting full. Since the nodes of the cluster all have space , 40GB only used ~600MB for installation, I was thinking of resizing their / partition and add another partition so we can have like /home2 /home3, etc.
If we ever need to rebuild the cluster or the image, then I don't have to worry about the imager destroying user data and find a place to back them up. But if that's not possible, I won't worry about repartition the disk, and just create the /home directory in / partition.

Hello, Suppose I have the hard drive of the client node already partition in such a way, and it has 3 partitions, eg:
/boot = /dev/hda2 / = /dev/hda3 /home = /dev/hda5
I want the node to download the image from the master, but how do I set up so that the imagre only installs stuff in the /boot and / partition, but without creating its own partition and messing up with my /home? This is necessary for example if I already have data in /home and just want to recreate the image.
Thanks. RDB
