Abstract
A system, method, and machine-readable storage medium for recovering data in a distributed storage system are provided. In some embodiments, the method includes identifying a failing storage device of a first storage node having an inaccessible data segment. When it is determined that the inaccessible data segment cannot be recovered using a first data protection scheme, a first chunk of data associated with the inaccessible data segment is identified and a group associated with the first chunk of data is identified. A second chunk of data associated with the group is selectively retrieved from a second storage node such that data associated with an accessible data segment of the first storage node is not retrieved. The inaccessible data segment is recovered by recovering the first chunk of data using a second data protection scheme and the second chunk of data.
