Abstract
A method includes determining a garbage collection list for a data storage structure of a node in a data storage system, the garbage collection list including one or more layout map identifiers (IDs) for garbage collection. A data fragment stored on the data storage structure is located at a first location and a layout map ID associated with the data fragment is determined. A determination is made whether the layout map ID associated with the data fragment matches a layout map ID for garbage collection in the garbage collection list. If the layout map ID associated with the data fragment matches a layout map ID for garbage collection in the garbage collection list, a determination is made whether the data fragment is present at a second location on the data storage system. If the data fragment is present at a second location on the data storage system, the data fragment at the first location is determined to be a garbage fragment and deleted from the data storage system.
