Direct ssh
$ ssh <node name> 'reboot'
or, some nodes
$ rocks run host <node 1> <node 2> ... <node n> 'reboot'
or, all compute nodes,
$ rocks run host compute 'reboot'

--Rick

Hi,

No, you'll need to set the install action in the database, so that the frontend knows that it needs to be reinstalled.

$ rocks set host boot <node name> action='install'

$ ssh <node name> 'reboot'

--Rick

If I do $ sh <node name> 'reboot', will it reinstall the OS automatically
from the headnode while restarting?

Thanks.
