To reinstall OS on compute node use:
rocks list host boot rocks set host boot <hostname> action=install ssh <hostname> "shutdown -r now"
This assumes that the boot order on compute node is properly set to boot from network.
By default there is /state/partition1 partition created on compute nodes. This partition is not affected during the reinstall process. Any data on this partition remains as it is after the reinstallation.
