Abstract: Embodiments include estimating a workload of a re-synchronization task for a data component in a logical storage system. Embodiments include detecting a connection from the data component, wherein the data component was previously disconnected. Embodiments further include determining a layout of the logical storage system. Embodiments further include estimating the workload of the re-synchronization task based on the layout. One or more actions may be performed based on the estimate.

Abstract: Embodiments include estimating a workload of a resynchronization task for a data component in a logical storage system. Embodiments include detecting a connection from the data component, wherein the data component was previously disconnected. Embodiments further include determining a layout of the data storage system. Embodiments further include estimating the workload of the resynchronization task based on the layout. If the layout indicates that the data component has an active mirror component, embodiments include estimating the workload to be a used capacity of the active mirror component. If the layout indicates that the data component does not have an active mirror component and that the data component has a stale mirror component, embodiments include estimating the workload to be a sum of a used capacity of the stale mirror component and an estimated size of missed input/output operations. One or more actions may be performed based on the estimate.
