Abstract:
1. A method of data processing in a cluster system, the method comprising: in a cluster configuration database residing on a trusted shared data storage device of a host node of a cluster, defining multiple nodes as members of the cluster; with reference to the cluster configuration database, centrally assigning a respective one of a plurality of unique device names to each of a plurality of shared storage devices in the cluster without querying the plurality of shared storage devices for device names, wherein the assigning includes: a particular node among the nodes defined as members of the cluster by the cluster configuration database searching the cluster configuration database on the trusted shared storage device for a device identifier matching a device identifier of a shared storage device hosted by the particular node, wherein the particular node is a different node than the host node; in response to finding a matching device identifier in the cluster configuration database, the particular node renaming, in a local configuration maintained at the particular node, a storage device associated with the matching device identifier with a unique device name assigned to that storage device in the cluster configuration database; and in response to a stimulus indicating configuration of an added node into the cluster:
