Abstract
A processing device obtains a write operation which comprises first data and second data to be stored in first and second strips of a given stripe. The processing device stores the first data in the first strip and determines that the second strip is unavailable. The processing device determines a parity based on the first data and the second data and stores the parity in a parity strip. The processing device updates metadata to indicate that the second data was not stored in the second strip. In some embodiments, the updated metadata is non-persistent and the processing device may be further configured to rebuild the given stripe, update persistent metadata corresponding to a sector of stripes including the given stripe and clear the non-persistent metadata based at least in part on a completion of the rebuild.
