Okay I will look into it,
So far as I saw, i cant find the "mirror core" one..what kind of mirror
cores are supported and what they will do? I googled for it but no docs for
this..
I want to build a mirrorset on my nforce3 250GB raid ..so far when i use
nosync the two disks get different when i copy something to the dm-mirror
set..any cloues..should I use sync?
Thanks again

Source ;)
Read about table spec in mirror_ctr() in drivers/md/dm-raid1.c.
Eg.:
0 160086522 mirror core 2 64 nosync 2 /dev/sdc 0 /dev/sdd 0
would set up a set with 2 mirrors using a core (transient) dirty-log if you
feed it into "dmsetup create".
