Abstract
A computer-implemented method, according to one embodiment, includes: determining that a data storage drive in a first array has failed, determining a location to rebuild the failed data storage drive, instructing performance of a rebuild operation at the determined location, determining one or more data storage drives in one or more arrays having a combined amount of available space that is sufficient to mirror data and/or parity information of the first array, instructing mirroring of the data and/or parity information of the first array in parallel with performing the rebuild operation, instructing deletion of the mirrored data and/or parity information of the first array from the one or more data storage drives in response to the rebuild operation being completed, and instructing reallocation of the space in the one or more data storage drives used to mirror the data and/or parity information of the first array as available space.
