5.8 HP Insight CMU diskless environments
5.8.1 Overview
HP Insight CMU provides two methods of provisioning a diskless OS with NFS:
•
The legacy method in HP Insight CMU, called system-config-netboot.
•
A new method based on the open-source oneSIS software package.
Both methods configure a central read-only root file system on an NFS server.
The system-config-netboot method also configures per-node read-write file systems on the
NFS server. Each diskless client mounts the read-only root file system, and then mounts their unique
per-node read-write files and directories over the read-only root file system. The result is that all
diskless clients share the read-only root file system, but write to their own per-node file system on
the NFS server.
