Hi list I wonder if MD RAID software is kind of self healing. That is, if a read operation gets an IO error, then the logical sector of the RAID can be recreated from the other sector(s) of the raid, and then written out on the block which gave a read error. His could work both for the mirrored RAID types, and for the parity orientet RAID types. Is that implemented in MD RAID? Similarily the self healing process could be part of the monitoring background processes.
