Alright friend :-)
I just completed it successfully!
I first created identical partitions in each hard disk and marked them
as RAID Physical volumes. The I created the RAID devices and then
specified mount points and ReiserFS :-)
It worked al right and easy but when I installed the boot loader I
think it got installed only on the hd0 and not on hd1!!!
how do I verify this???
and how can testif the RAID is woring fine???
Thankyou so much
Kind Regards
Siju
