Abstract
A resynchronization operation (300) adapts according to activity histories (148) within a storage platform (100). An owner node (A) and a backup storage node (B) may track activity such as the IO operations begun and use recent activity to determine respective amounts of data the owner (A) and backup (B) can expect to process without unacceptably degrading storage services. The owner (A) transfer resynchronization data in chunks, each having a size limited by the current amounts the owner (A) and backup (B) determined from current activity. When activity is low or idle, large chunks may be sent to quickly complete resynchronization, while a busy system uses smaller chunks such that the system performance is not adversely affected.
