Abstract
The described technology is generally directed towards data storage using a node cluster, and garbage collecting unused chunks (data storage units) in the cluster based on which node owns the particular unused chunks. A node determines which chunks are in use, and exchanges datasets identifying those chunks with other nodes such that the other nodes know which of the chunks that they own are in use. When a node obtains the dataset identifying the chunks in use, the node determines the chunks not in use by a difference of those owned and those in use. This difference dataset is used to garbage collect owned, unused chunks. Garbage collection via this technology is able to be performed in a single cycle.
