=======================
I am adding a new disk to increase my (/) partition.
I have followed up the exact steps provided in link
http://thewiringcloset.wordpress.com...x-without-lvm/
and it screwed up my box and now i am getting kernel panic error.
only thing i did i had taken clone and did all my experiment.
so my prod box is alive. still i am struggling in re-sizing.
