Hi all,
There are four different "checksumming algorithms" -- really, disk
layouts, in Linux. Is there anything "known" about the relative
performance of these? The default for mdadm and mkraid is currently
left-symmetric; is that a sensible default?
I'm asking because I'm trying to get my RAID-6 project going, and
these layouts get a lot more complex with two redundancy drives.
Thus, I'm considering just supporting one disk layout at this point,
and I'd like to pick one :)
