i'm working on a database which consists of datafiles in filesystems
(referred to as cooked in some technical documents). i want to look at
the performance difference with all the files raw i.e. using logical
volumes to store the data. i know its possible to backup raw files
using the dd command. what i'm interested in finding out/understanding
is how to perform the opposite process i.e. convert from a 'cooked' to
'raw' storage system for an existing instance containing data. can i
use a dd command to copy data from file to logical volume? is an
export/import the only option? i'm going to be performing a number of
tests myself and will post findings here. any other knowledge on
subject appreciated.
