description Garbage collection is performed for a virtualized storage system whose virtual address space is addressed in extents. Valid data in source extents is copied via a cache into destination extents. Once all valid data in a source extent is copied into one or more destination extents, the source extent may be reused. A source extent is released for reuse only after the one or more destination extents that received the valid data copied from the source extent are determined to be full, and the valid data copied from the source extent to the destination extent via the cache is flushed out of the cache.
