[Linux-cluster] Cluster design questions



I have two simple questions for the experts out there. My
configuration will be RHEL 4 and GFS6.1.

1. When setting up the cluster membership should I use a private
network address for the members even if it is 100mb or would the
public data interface which is gigabit provide beter performance? I
guess the question is really how much network traffic does the DLM
create?

2. If I have a GFS /export filesystem can I then mount other GFS
filesystems under that and on multiple nodes, i.e., can I have
/export/home1, /export/home2, /export/home3 all mounted under /export
and all being GFS filesystems and all mounted on multiple servers? Do
the mount points cause any confusion across the nodes.

Thanks.
