clusterctl provision reinstall

Reinstall a node set from the network

Synopsis

Reinstall nodes: configure the network boot, set the machines to boot from the network once, remove their host keys, and reset them.

This destroys everything on the nodes. Before it asks, it resolves every node’s address, boot path, service processor and BMC credential, checks that each boot path exists on the PXE host, and asks Slurm whether the nodes run jobs, so that nothing is changed for a set that would stop half way. It refuses protected hosts, lists each boot path with its nodes, and above the configured host count asks for the count to be typed back.

A node that Slurm reports running a job, or cannot say about, is refused unless –lose-jobs is given; –force gets past a protected host, not this check. With –no-reset nothing is reset, so Slurm is not asked, and each node reinstalls at its next network boot.

The boot override is set over Redfish, so a node whose bmc.order does not start with redfish is refused.

When a step fails, the boot links and boot overrides of every node that was not reset are removed again. Whatever could not be removed is named, with the commands that remove it.
