> Project: Ignite

> Labels: ignite-3
>
> If, during an Ignite node startup, it finds a ClusterResetMessage stored in
> its Vault, it does the following (before starting the networking):
> # Assign cluster ID from the message instead of the cluster ID stored in the
> local CMG data for the network handshake validation
> # Start the network
> # If the cluster ID stored in the local CMG data is different from the one
> from the message, then:
> ## Destroys the local CMG data and CMG Raft storages (meta, snapshots, log)
> ## Initializes a new CMG Raft node using the new CMG nodes (from the
> message) as voting set
> ## Submits a CmgInitCommand (having new CMG nodes, MG nodes from the
> message, new cluster name and ID, new cluster ID history) to the new CMG
> # Removes the message from the Vault
> # Proceeds with the normal startup
