Abstract
A method according to one embodiment includes defining a new encryption band with a length that is consistent with a redundant array of inexpensive disks (RAID) parity strip; freeing a working extent in a working stride on the RAID. In an iterative process until each stride in a source band is depleted of data: marking a source extent in a source stride from which to gather data to be re-encrypted; marking parity inconsistent in the working stride in the new encryption band; performing a second iterative process; and freeing the working extent. The second iterative process is performed until each extent in a source stride is depleted of data. Additional systems, methods and computer program products are also presented.
