Claim Text:
1. A method of cluster management in a shared nothing cluster, wherein the shared nothing cluster comprises one or more data nodes each having an operating system and applications running thereon, wherein the data nodes in the shared nothing cluster do not share data storage devices, and wherein the method comprises: collecting, by a cluster manager, cluster configuration information associated with the data nodes in the shared nothing cluster, wherein the data nodes do not share access to data storage devices, wherein the cluster manager is configured to handle operating system and application faults in the data nodes according to configuration information about the data nodes in a shared nothing cluster, wherein the configuration information is collected by a master node in the shared nothing cluster, wherein the configuration information describes an operating system and applications running in the master node and multiple data nodes within the shared nothing cluster, and wherein the master node superintends the multiple data nodes; obtaining, by the cluster manager, a tabulation image based on the collected cluster configuration information; and in response to determining that operating system breakdowns occurred on one or more of the data nodes, sending, by the cluster manager, the obtained tabulation image to faulted data nodes to recover their operating systems.
