Abstract: Example implementation relates to a method for managing movement of set of entities associated with sampled data units in a cluster of nodes of a distributed storage system. A database is maintained for sampled data units received from the cluster of nodes. The method includes maintaining lineage information for the set of entities associated with the sampled data units received from each node. Based on the lineage information of a source node, a data set for migration is determined.

Abstract: Example implementation relates to generating a database for a set of entities associated with sampled data units of a storage system. A first data structure in the database maps, in a bit vector, each entity with a sampled signature of a set of sampled signatures. The set of sampled signatures are associated with the sampled data units. The set of entities associated with the set of sampled signatures are managed using the first data structure.

Abstract: For storing data in a storage device, a storage allocation request may be received. The storage allocation request may include a logical offset of data to be stored. Further, a chunk size of the storage device and a device offset for a free region on the storage device may be received. An offset value may be computed based on the chunk size, file system block size, the device offset, and the logical offset. A device start address, for storing the data in response to the storage allocation request, can be determined by offsetting the device offset with the offset value.
