Abstract
Aspects of the present invention disclose a method for a two-node storage system. The method includes one or more processors creating a plurality of first logic unit groups in a first storage node of a storage system. The method further includes mapping each of the plurality of first logic unit groups to a number of storage slices from different storage devices in the first storage node. The method further creating a plurality of second logic unit groups in a second storage node of the storage system, by mirroring storage slices from a storage device in the first storage node to multiple storage devices in the second storage node. In response to identifying a failure of a first storage device in the first storage node, the method further includes recovering lost data based on data in the second storage node.
