NODE DISCOVERY AND CLUSTER FORMATION FOR A SECONDARY STORAGE APPLIANCE

摘要

Techniques are disclosed for identifying “free” compute nodes that have not been configured as a member of a secondary storage system. As disclosed, a node may automatically detect that it is a free node (i.e., one available to join a distributed computing cluster which provides the secondary storage system or to form a new cluster). When a node detects that it is not part of a cluster, the node may build an initial network configuration and begin advertising itself as a free node. Once the initial network state is available, the node may broadcast advertisements observed by a management tool and joined to the secondary storage system.

1. A method for indicating a presence of a node in a distributed computing cluster, the method comprising:
determining, by operation of one or more computer processors on the node, that the node has not been configured as a member of a distributed computing cluster; and in response:
configuring a first network state on the node,determining a node identifier (ID) for the node, andbroadcasting one or more messages advertising the node ID and a network address of a configuration interface hosted by the node.
