Abstract: One example method includes identifying a data block as being in a corrupted state, and calculating a value of a identifier corresponding to the data block, where the value of the identifier is based on contents of the data block. The value of the identifier is then compared with a value of another identifier that is part of a stored access record for the data block. Based on results of the comparison, the virtual machine is either identified as the cause of corruption of the data block, or the virtual machine is eliminated as being the cause of the corruption of the data block.

Abstract: A hierarchical multi-level heterogeneous cluster data system having processing nodes at each of a plurality of cluster levels configured for different data tiers having different availability, accessibility and protection requirements. Each cluster level comprises groups of processing nodes arranged into a plurality of failover domains of interconnected nodes that exchange heartbeat signals to indicate that the nodes are alive and functioning. A master node of each failover domain is connected to a master node of a parent failover domain for exchanging heartbeat signals to detect failures of nodes at lower cluster levels. Upon a network partition, the nodes of the failover domain may be merged into another failover domain at the same or a higher cluster level to continue providing data services. The cluster has a global namespace across all cluster levels, so that nodes that are moved to different failover domains can be accessed using the same pathname.
