Abstract:
The present invention provides a system and method for virtual block numbers (VBNs) to disk block number (DBN) mapping that may be utilized for both single and/or multiple parity based redundancy systems. Following parity redistribution, new VBNs are assigned to disk blocks in the newly added disk and disk blocks previously occupied by parity may be moved to the new disk.
