Boot-related commands
Reinstall a node
Nodes' BIOS should be set to boot from PXE (network) first and then the local hard drives. The PXE server changes the PXE configs depending on what bootaction
you've set for the node in the rocks database. To instruct a node to reinstall on the next boot:
# rocks set host boot compute-0-6 action="install" # rocks set host installaction compute-0-6 action="install ilri" # rocks run host compute-0-6 'reboot'
Run memtest
# rocks set host runaction compute-0-8 action="memtest" # rocks set host boot compute-0-8 action="os" # rocks run host compute-0-8 'reboot'
Monitor installation progress
You can monitor a node's progress during the installation using VNC. Make sure you're inside X on the head node, or logged in via SSH with X forwarding:
$ sudo rocks-console compute-0-8
