Good day. I am looking for some information, and hope the readers of this list might be able to point me in the right direction: Here is the scenario: In RAID5 ( or RAID6) when a file is written, some parity data is created, (by some form of XOR process, I assume), then that parity data is written to disk. I am looking to find the algorithm that is used to create that parity data and to decides where to place it on the disks. Any help on this is deeply appreciated. -- With our best regards, Maurice W.
