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.

wikipedia has some useful information, and definitely has a link to a
paper that described raid6 on linux.
