The startsys Command

The --image_and_boot option images all the nodes that require imaging before booting them. You can also select a subset of nodes for imaging and booting. You can specify options to designate Flamethrower or the rsync utility for imaging the nodes.

Using both the --image_and_boot and the --force options, you can image a node that is already running.

The --image_retry_count specifies the number of times to retry the imaging operation on the target nodes.

The --max_at_once limits the number of nodes that are booted at one time, thus helping to eliminate a considerable drain on the site's power system.

The --test option returns a list of all the nodes that require imaging.
